Each Trial is a strategy a real species uses, turned into something you can run yourself in about ten minutes. Each card says what to do and why it helps.
What each Trial asks you to do, and what it does for you. Reading a Trial needs no account. 3,017 Trials across 2,325 species. Showing 181–240.
The Trial
Change the permanent shape of one thing today so the protection is structural, and remove whatever step you currently have to remember to do.
Why it helps
Protection that depends on you remembering a step fails on the day you are tired. Building it into the shape means it holds whether you are paying attention or not.
2 minDifficulty 2
The Trial
Offer a genuine replacement today for something you want someone to stop doing, rather than asking them to stop.
Why it helps
Asking someone to stop something they depend on means they agree with you and continue anyway. Replacing it is what actually changes what they do.
2 minDifficulty 1
The Trial
Work only inside the window your main unsolved limitation allows today, and seal up rather than pushing through the rest.
Why it helps
Pushing through hours your unsolved limitation makes impossible produces nothing and costs you the next window. Sealing up keeps you able to use it.
2 minDifficulty 1
The Trial
Build one dedicated detector today for the specific unwanted attention your own visibility attracts, tuned to that and nothing else.
Why it helps
Being visible attracts specific unwanted attention, and a general alertness will not catch it. A detector tuned to that one thing gives you the warning.
2 minDifficulty 2
The Trial
Change the shape of one thing today so that the knock you cannot prevent no longer loses it: the saved draft, the fixed position, the contained spill.
Why it helps
Trying to prevent every knock on a bare ledge is impossible and you will lose it once. Shaping the thing so a knock does nothing is permanent.
1 minDifficulty 3
The Trial
Set up one arrangement today where a daily external cycle does the circulating, then wait rather than driving it yourself.
Why it helps
Driving circulation yourself means it stops the moment you do, every evening. An external daily cycle keeps it going while you are not there.
2 minDifficulty 2
The Trial
Fold one long requirement inward today so it fits inside your existing footprint, rather than expanding to accommodate it.
Why it helps
Expanding to accommodate a long requirement means losing the small size that let you work where you do. Folding it inward keeps both.
1 minDifficulty 4
The Trial
Work out today what one odd feature of yours actually reports to other people, and either lean on it or correct the impression.
Why it helps
An odd feature is reporting something about you whether you intend it or not. Finding out what means you either use it or stop it misleading people.
2 minDifficulty 2
The Trial
Pick one evening hour today and spend it entirely still in one place, acting on nothing, until one thing clearly deserves action, then act on that one thing only and stop.
Why it helps
Acting on everything that crosses your evening leaves you spent and nothing settled. Holding still until one thing clearly deserves it means the one action you take actually lands.
2 minDifficulty 1
The Trial
Pick one hour today when everyone around you will be busy and do nothing productive in it, deliberately. No tasks, no catching up, no tidying. Stay available instead: in the room, reachable, unhurried. When someone needs something in that hour, you are the one with capacity to give it.
Why it helps
Filling every hour with work means you have nothing left when something actually urgent lands, and you resent it. A deliberately empty hour is the capacity you never budget for and always need.
2 minDifficulty 1
The Trial
Hold total stillness on one thing today for a defined period, and state honestly what you are giving up during it.
Why it helps
Holding still without pricing what it costs means doing it too long and losing more than you saved. Stating the cost tells you how long to hold.
2 minDifficulty 1
The Trial
Pick something of yours that looks healthy from outside, the system, the group, the routine, and check what is actually inside it today: count the active members, the real usage, the remaining stock. Say the number out loud.
Why it helps
Things that look fine from outside are where the worst surprises come from, because nobody checks what is inside. One honest count takes ten minutes and tells you whether you have a problem now or in a year.
2 minDifficulty 2
The Trial
Extend the reach of one thing today well beyond its visible footprint without making the thing itself bigger, then hold position rather than moving.
Why it helps
Growing the visible part of something to reach further makes it costly and obvious. Extending the reach without the footprint gets you the same coverage unnoticed.
2 minDifficulty 1
The Trial
Add a seal rather than more bulk against one persistent condition today, and push straight through one obstacle instead of going around it.
Why it helps
Adding bulk against constant wet means carrying wet bulk. A seal keeps you dry for a fraction of the weight and the thicket stops mattering.
2 minDifficulty 1
The Trial
Take whatever about one thing cannot be made unobtrusive today and concentrate it into a single small area rather than leaving it spread out.
Why it helps
Unavoidable visible parts spread across something make all of it noticeable to anyone looking. Concentrating them in one small area means the rest disappears for you.
2 minDifficulty 2
The Trial
Make one thing of yours larger without making it heavier today, by hollowing it out rather than adding material.
Why it helps
Making something bigger by adding material means carrying the weight everywhere. Hollowing it out gets you the size and an extra function for nothing.
2 minDifficulty 2
The Trial
Take something just beyond safe reach, physically or otherwise, and secure your footing first: brace against the solid thing, get the agreement, fix the base. Only then reach out for it with both hands free.
Why it helps
Walking out to where the prize is puts your weight on the part most likely to give. Anchoring on solid ground first means you can reach further and stop worrying about the thing under you.
2 minDifficulty 2
The Trial
In a sink or shallow basin, use one removable suction cup or weight to keep a lightweight floating object fixed while water moves around it.
Why it helps
You turn rock anchoring into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 1
The Trial
Roll a sheet of paper into a thin tube, fringe the top half into a feathery plume, and push its base into a deep bowl of dry rice, packing the grains gently around it. Set a fan on its lowest setting and let the plume sway in the airflow for sixty seconds; if it falls, bury the base deeper and start again.
Why it helps
A calm little build that shows how depth and flexibility beat stiffness.
12 minDifficulty 1
The Trial
Stand a small baking tray inside a larger washing-up bowl or roasting dish (not in the sink), prop one end so it slopes gently, spread a layer of sand or fine gravel over it, and push a mesh tea strainer upright into the sand until it is half-buried, marking its spot with a pen line on the tray rim. Stir a spoonful of loose tea leaves into a jug of water and, without touching the strainer again, pour it slowly across the top of the tray over about two minutes so the flow runs down past and through the strainer into the bowl; do not drink the water, and afterwards tip the sand and leaves onto soil or into the bin, never down the drain.
Why it helps
A calm, hands-off experiment that shows how much an anchored filter can catch when the flow does the work.
15 minDifficulty 1
The Trial
Before extending into something ambitious today, set the anchor further back than feels necessary: the extra backup, the earlier checkpoint, the deeper agreement. Then extend.
Why it helps
Anchoring just enough means your reach is limited by the nearest point of failure. Setting it deeper than seems necessary is what lets you extend much further safely.
2 minDifficulty 1
The Trial
Anchor one task today with something other than your hands so both are free for the work, and do none of the holding with them.
Why it helps
Using one hand to hold and one to work means every job takes twice as long and is done worse. Anchoring with something else gives you both hands back.
2 minDifficulty 2
The Trial
Anchor yourself today with something other than the capacity you need for the work, so that capacity becomes free.
Why it helps
Using your working capacity to hold yourself in place means it is never available for the work. Anchoring with something else frees all of it.
2 minDifficulty 2
The Trial
Stay anchored at one point today while reaching for something with the other end of yourself, and release nothing in order to take it.
Why it helps
Letting go of your position to reach something means that if you miss you have lost both. Staying anchored while you reach means a failed attempt costs you nothing.
1 minDifficulty 3
The Trial
Anchor one position permanently today and extend into the flow from it, taking items individually without travelling at all.
Why it helps
Travelling to the supply means most of your effort is transit and you arrive after others. A fixed anchor in the flow brings it all past you.
2 minDifficulty 2
The Trial
Stand a baking tray in the sink tilted a few degrees under a gently running tap and lay a textured bed along it, such as a strip of rubber non-slip mat or a line of small pebbles, so water flows over it. First adjust the tilt and the flow until one coin wrapped in flat, unshaped foil is clearly swept down the bed, then keep that exact tilt and flow and reshape the same foil and coin into a low diver with folded foil feet that grip the texture, adjusting its front, wings and feet until it holds position against the flow for ten seconds.
Why it helps
A hands-on fluid-dynamics puzzle that makes you think like an engineer.
15 minDifficulty 3
The Trial
Build or arrange one way today to reverse out of a confined position without needing room to turn, and test it.
Why it helps
Entering confined positions without a way to reverse means getting stuck and having to force your way out. One tested reversal makes them all usable.
2 minDifficulty 2
The Trial
Name today which of your tools actually decides outcomes and which only creates position, and stop confusing the two in how you prepare.
Why it helps
Investing in the tool that only creates position means you arrive well-placed with nothing to finish it. Separating the two tells you where your effort belongs.
2 minDifficulty 1
The Trial
Take a bearing before leaving one crowded situation today and hold a straight line away from it rather than moving fast.
Why it helps
Leaving a crowded place quickly without a bearing curves you back into it with what you took. One bearing first is the whole difference.
1 minDifficulty 4
The Trial
Set yourself up today so you can move in any direction without repositioning first: no single orientation, no committed facing, exits on every side.
Why it helps
Being committed to one direction means every change costs you a turn, and in a fast situation you do not get one. Omnidirectional setup removes that.
1 minDifficulty 3
The Trial
Visit every one of your open options today, briefly, rather than relying on the one you use most, so none of them closes.
Why it helps
Options you never use quietly close and you find out when your main one fails. One brief visit each keeps all of them available.
2 minDifficulty 1
The Trial
Take a messy or nearly failed small setup and identify the single smallest change with the highest leverage. Apply only that change, then capture the before-and-after state.
Why it helps
A nearly-dead setup works again, and you know exactly which change did it.
8 minDifficulty 1
The Trial
Do something today openly that you would normally do quietly: state the intention first, in front of the people it affects, before you begin.
Why it helps
Doing things quietly to avoid objection is what makes them look like something to object to. Stating it first usually gets you agreement instead of a fight.
2 minDifficulty 1
The Trial
Approach at least five possibilities today with no intention of committing, read how each responds, and walk away from the ones that hold firm.
Why it helps
Committing to the first thing you approach means you never learn what the alternatives would have said. Five approaches and four walkaways costs you one day.
1 minDifficulty 3
The Trial
Choose a task you would normally start in one movement and approach it in three deliberate stages, pausing fully at each before going further. Only the third stage touches the work.
Why it helps
A task you usually botch the start of begins cleanly, because you arrived at it rather than at it.
8 minDifficulty 2
The Trial
Defend one old method of yours today by establishing that it still fits current conditions, rather than replacing it because it is old.
Why it helps
Replacing something because it looks dated means losing a fit you cannot easily rebuild. Checking whether it still works takes an hour.
2 minDifficulty 1
The Trial
Before the next thing you know will go badly in some predictable way, put the specific protection in place first: the written agreement, the backup, the gloves, the second opinion. Then do the thing.
Why it helps
You know exactly how this one usually goes wrong and you go in anyway hoping it will not. One specific protection put in beforehand costs ten minutes and removes the outcome you keep repeating.
2 minDifficulty 1
The Trial
Strengthen your baseline durability on something today before taking on any confrontation, and take on none until that is done.
Why it helps
Confronting something before you are hard to disable means one exchange takes you out. Doing the durability first makes the same confrontation cheap.
2 minDifficulty 1
The Trial
Identify what is making you rush one particular thing, the deadline, the watcher, the lack of a buffer, and put one protection in place that removes it: the extension asked for, the buffer built, the expectation reset. Then do the thing at a deliberately slow pace.
Why it helps
Rushing produces work you have to redo, and you rush because something is exposed. Securing the protection first costs one conversation and lets you work at the pace that gets it right.
2 minDifficulty 1
The Trial
Protect the side of something you normally leave exposed today, the underside, the edge case, the quiet assumption, and then go somewhere you had ruled out.
Why it helps
Your exposed side is the one that decides where you can go, and you have stopped seeing it. Covering it opens places you had written off.
1 minDifficulty 3
The Trial
Set yourself up today so that staying ready for something costs you nothing to maintain: the open calendar slot, the prepared answer, the kit left out.
Why it helps
Readiness that costs you effort every day gets dropped exactly before it is needed. Setting it up so it costs nothing means it is still there months later.
2 minDifficulty 1
The Trial
Arrange a small catching or collecting area so its usable surface is larger than when you started. Take a before-and-after photo.
Why it helps
The catching area holds more than it did, so things stop landing on the floor.
8 minDifficulty 1
The Trial
Build or improve one structure today that makes things come to you, then wait rather than pursuing anything.
Why it helps
Waiting without having built anything is just waiting, and nothing arrives for you. Building the structure first is what makes the same waiting pay.
1 minDifficulty 4
The Trial
Set the position, background and light for one reveal today before revealing anything, and make the reveal itself the shortest part.
Why it helps
Revealing something before the conditions are set means the best version of your work is never what anyone sees. Setting the angle first makes the same reveal land properly.
1 minDifficulty 3
The Trial
For the next thing you are about to attend or join, do the first step before you get there rather than after: the question written, the file open, the form half-filled, the first line drafted. Turn up with it already underway and continue from there.
Why it helps
Arriving ready to begin means the first ten minutes go on warming up while someone else takes the opening. Turning up already moving puts you ahead before anyone has settled.
1 minDifficulty 3
The Trial
Get a group to do one thing at the same time today rather than each in their own time: the simultaneous ten minutes, the shared push, everyone filing it at once. Agree the moment and all move together.
Why it helps
Letting everyone do it in their own time means it trickles out over a fortnight and never feels done to you. One agreed moment where the group moves together finishes it in an afternoon.
2 minDifficulty 2
The Trial
Approach one thing from underneath today, where the value sits and the protection does not, rather than through its armoured surface.
Why it helps
Attacking the armoured surface wears you down and the value is not there anyway. Coming from underneath reaches it with none of the resistance.
2 minDifficulty 1
The Trial
Pick something new that has just opened up in your world, a tool, a group, a project, a format, and get in during its first week rather than waiting to see if it lasts. Join, set up, or contribute something today.
Why it helps
Waiting to see whether something lasts means you join when all the good positions are taken. Getting in during the first week costs almost nothing and is usually the only time it is cheap.
2 minDifficulty 2
The Trial
Name one problem you have been solving by searching - reading, scrolling, trial and error. Find the person who has already lived it, ideally the oldest one available to you, and ask them today in person or on a call. Ask for the route, not the opinion: what they did, in order, and what they would skip.
Why it helps
Searching your way through a problem someone else already solved costs you weeks and usually lands you somewhere worse. One conversation with a person who has the route saves most of that time.
2 minDifficulty 2
The Trial
Ask the oldest person available today how something was handled the last time conditions were this bad, and write down what they say before acting on anything yourself.
Why it helps
Working out a rare situation from scratch means you repeat a mistake somebody already paid for. One question to someone who was there saves you the whole cycle.
2 minDifficulty 4
The Trial
Reach past the front row to the back or bottom shelf of your cupboards and take out three sealed items that have sat untouched for weeks, such as crackers, a tin of beans or dried fruit. Check each date and skip anything past its use-by, then assemble one snack from them with no cooking.
Why it helps
Three forgotten items get eaten instead of expiring at the back of the cupboard.
10 minDifficulty 1
The Trial
Inside a crowded space you work in today, assemble one distinguishable thing of your own from borrowed pieces, and put it out where the crowd is.
Why it helps
Being one more indistinguishable voice in a crowded space means your work is credited to the space. One assembled distinctive thing fixes that.
2 minDifficulty 3
The Trial
Find out today what one thing you have assumed about actually does, before continuing to act on the assumption.
Why it helps
Acting on a reputation that turns out to be exactly wrong wastes everything you built on it. One check costs you an afternoon.
2 minDifficulty 1
The Trial
Deliberately receive the same information through two differently-positioned channels today, and use the difference between them to locate something.
Why it helps
Two identical channels give you the same information twice. Two differently positioned ones let you locate something neither could find alone.
2 minDifficulty 1
The Trial
Work out today what minimum frequency your situation actually requires, and hold that frequency rather than treating it as a preference.
Why it helps
Treating a required frequency as a preference means you fall behind without noticing. Calculating the minimum tells you what is actually non-negotiable.
1 minDifficulty 3
The Trial
Attend only to your immediate neighbours today rather than to the whole group or any leader, and match their changes.
Why it helps
Trying to track the whole group or wait for a leader means you turn last. Watching only your neighbours means you turn with everyone at once.
2 minDifficulty 2
The Trial
Choose one limit you keep stating but not keeping, such as no phone after ten at night or no snacks at your desk. Put a real barrier in place right now: move the charger out of the bedroom, take the snacks to another room, block the app on a schedule. Show the limit and the barrier together.
Why it helps
A limit you only announce gets tested and broken, mostly by you. Putting one real barrier behind it means the rule holds on the nights your willpower is low, so you stop renegotiating it.
2 minDifficulty 1
The Trial
Wrap a small sturdy object in a bold spotted warning pattern and demonstrate one harmless property that genuinely makes it hard to crush, bend, or open. Photograph the warning and demonstration.
Why it helps
Practises credible signalling by pairing a memorable visual warning with a defence that is actually present rather than bluffing.
7 minDifficulty 1
The Trial
Add one one-way feature today to something you keep losing hold of, so what enters cannot slide back out.
Why it helps
Things you take hold of slide back out because nothing stops them, and you blame your grip. One one-way feature means they never do.
2 minDifficulty 2
The Trial
In a bath, shower tray or outdoors, have a helper stir one level tablespoon of dried lentils into a bucket filled with about ten litres of water. Before every jugful, stir the bucket hard with the jug and scoop at once, while the lentils are still swirling, then pour the jugful through a sieve into a second bucket, never lifting the full bucket; keep going until the first bucket is empty, then tip everything the sieve caught into the tablespoon.
Why it helps
A splashy, satisfying job that makes it obvious why a jellyfish-eater has to be enormous.
15 minDifficulty 2
