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 601–660.
The Trial
Lay five cushions in a row on a carpeted floor with small gaps between them. Crawl from the first to the last, moving one hand or knee at a time, so three limbs are always pressed onto a cushion.
Why it helps
A slow, surprisingly demanding coordination challenge.
5 minDifficulty 2
The Trial
Drape blankets over a table, closing the sides with boxes or cushions, to make one low hollow with a single entrance, big enough for three. Sit quietly nearby with two willing housemates, family members or friends and set a random-interval timer as the owl; when it sounds, all three crawl calmly into the hollow and rest there together, quiet and settled, for ten minutes.
Why it helps
Ten cosy minutes with people you like.
15 minDifficulty 1
The Trial
Ask a helper to hide eight small toys under cushions, blankets and laundry heaps around one room. With a partner or child behind you, crawl single file, low and nose-down, probing each heap with your hands until all eight are found.
Why it helps
A giggly, cooperative search that works for any age.
12 minDifficulty 2
The Trial
Make the transformation obvious without explaining it.
Why it helps
Practises presentation and self-expression while producing a clear, entertaining transformation.
10 minDifficulty 2
The Trial
Add one bold gold, yellow or bright element to your outfit and make a deliberately overconfident entrance into a room. Hold the energy for thirty seconds.
Why it helps
Practises presence and playful confidence while producing instantly readable social proof.
10 minDifficulty 2
The Trial
Take something you have been blaming for a recurring problem and check the evidence today: look at when it actually happens, test without it, ask someone who would know.
Why it helps
Blaming the wrong cause means you keep treating something that was never the problem while the real one continues. One test usually settles it in an afternoon.
2 minDifficulty 1
The Trial
Pick one thing you usually attempt from too far away, a request or a difficult conversation. Spend the time to close the distance properly first, then make the attempt exactly once and stop regardless of the outcome.
Why it helps
Attempting things from too far out means you get refused and then try again from a worse position. Closing the distance first turns one attempt into the only one you need.
2 minDifficulty 1
The Trial
Tape a one-metre square on a clear, soft floor, set a bowl in its centre and scatter ten clothes pegs inside the square, some close to the edges. Get on your hands and knees inside the square and slowly creep around it, picking up one peg at a time and dropping it in the bowl, keeping at least one knee and one hand on the floor the whole time.
Why it helps
A few minutes of slow, low, mindful movement with a clear finish.
8 minDifficulty 1
The Trial
Put a paper shrimp on a table about three metres away and a tape line one metre in front of the table. Roll a newspaper into a tube with a loop of tape, sticky side out, on its tip; walk slowly to the line, taking at least twenty seconds, then with one quick thrust pick the shrimp up on the tip.
Why it helps
A playful test of patience followed by speed.
10 minDifficulty 2
The Trial
While you wear a blindfold and headphones, a helper lays a warm (not hot) wheat bag and two same-sized room-temperature decoys, such as folded tea towels, under different spots of a single unfolded bath towel or flat sheet on the floor, then waits three minutes so the warmth comes through. Creep up slowly on hands and knees, sweep the back of your hand once over the surface without pressing, and place one coin where you feel warmth; the helper then lifts the towel to reveal the warm bag.
Why it helps
A calm, curious test of a sense you rarely notice you have.
10 minDifficulty 2
The Trial
Put a small handful of cooked, cooled peas on a plate on a table. With your hands clasped behind your back, gather every pea into your mouth using only your lips, then show the empty plate.
Why it helps
A daft, surprisingly tricky snack that makes you laugh at yourself.
10 minDifficulty 2
The Trial
Gather something quickly in the exposed place today, then withdraw somewhere sheltered to do the slow processing, and do none of it where you gathered.
Why it helps
Doing the slow thoughtful part where you are interrupted means it takes three times as long and still comes out badly. Taking it somewhere sheltered fixes both.
2 minDifficulty 1
The Trial
Return to something you already made and improve it instead of starting something new: the old note, the existing page, the dish you cook often, the route you walk. Work the same plot and leave it visibly better.
Why it helps
Starting fresh feels like progress and leaves you with a field of unfinished things. Going back over the same plot is what actually makes one of them good, and good is the only version anyone uses.
2 minDifficulty 1
The Trial
Mark two 'water' zones with paper and move between them using only the dry spaces while carrying a small object.
Why it helps
Practises route adaptation when the obvious environment becomes unusable, while preserving the useful payload.
6 minDifficulty 2
The Trial
Cross a room while keeping a small mirror or glossy card angled so it never flashes a lamp or window toward the camera.
Why it helps
You turn wing transparency into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Cross one ordinary room from wall to wall as quietly as possible, keeping every heel strike silent.
Why it helps
You turn branch secrecy into one concrete experience with a visible finish.
10 minDifficulty 1
The Trial
Create a short route across a smooth surface using removable paper markers, then move an object along it without lifting it.
Why it helps
Develops controlled movement through continuous contact, useful for handling awkward objects without losing grip.
6 minDifficulty 2
The Trial
Create a harmless sticky-zone analogue with six paper squares on the floor. Cross it touching only three marked squares, without stepping anywhere else.
Why it helps
You cross using three contact points instead of six, which is a real change in how you move.
5 minDifficulty 2
The Trial
Lay six non-slip sheets of paper or mats on a clear floor and cross them in six quick steps, landing once on each without touching the floor between.
Why it helps
You turn impossible timing into one concrete experience with a visible finish.
5 minDifficulty 3
The Trial
Walk ten slow steps across a clear flat space with your arms spread wide, stopping completely after steps three, six and ten.
Why it helps
You turn highland agility into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Take a request that has been refused individually and bring it today as a group, with at least two other people making the same ask at the same time.
Why it helps
A request made alone is easy to refuse and you take it personally. The same request from three people at once is usually not refused at all.
2 minDifficulty 2
The Trial
Choose a space people usually skirt round the edges of, such as the middle of a park lawn, a school field or an empty hall. Walk straight across the middle at a slow, steady pace, counting five seconds for every step, without stopping, hurrying or drifting to the edge.
Why it helps
Hurrying across open space tells everyone, including you, that you do not belong there. Moving through it slowly and steadily teaches you that being seen in the middle of a room costs far less than you feared.
2 minDifficulty 1
The Trial
Redesign one filter or intake today so material passes across it rather than into it, so it does not need clearing.
Why it helps
A filter that material passes into needs clearing constantly and blocks when you are busy. Running the flow across it means it never stops.
2 minDifficulty 1
The Trial
Take one thing you normally do at the busiest, most visible time. Do it today at the quietest hour instead and at the smallest scale that still counts, and spend the busy hours out of view.
Why it helps
Doing your work in the busiest window means you compete for every bit of attention and get interrupted through all of it. The quiet hour costs you visibility and gives you the whole thing done.
2 minDifficulty 1
The Trial
Toss one small bowl of plain popcorn or crackers in chilli powder or paprika-and-chilli seasoning until it turns visibly red-orange and genuinely hot, then stand a crest of whole dried chillies upright on top. Leave a second bowl of the same snack completely plain and uncoloured, with no labels or food colouring on either.
Why it helps
A snack for sharing where the heat announces itself, so nobody gets an unwelcome surprise.
10 minDifficulty 2
The Trial
Keep today's baseline genuinely cheap and confine your intensity to one short burst, without blending the two at any point.
Why it helps
Blending your cruise and your burst means a baseline that tires you and a burst with nothing behind it. Keeping them separate gets you both.
1 minDifficulty 4
The Trial
Pick the toughest, most defended item on your list. Spend today applying blunt sustained force to that one thing instead of the easy items, and do not switch to anything softer.
Why it helps
Leaving the armoured item for later means it accumulates and starts blocking everything behind it. Spending one day applying blunt force to it is how it finally stops being on your list.
2 minDifficulty 3
The Trial
Collect about six rinsed, dried eggshells. Pick each one up with kitchen tongs and drop it into a sturdy mug or mortar, then crush them all with the flat end of a rolling pin or pestle until the grit is fine enough to sprinkle round plants.
Why it helps
A quiet, useful job that gives your garden plants a mineral top-up.
15 minDifficulty 1
The Trial
Choose one stubborn practical problem and break it into three smaller pieces you can handle separately. Finish the easiest piece first.
Why it helps
A hard problem becomes penetrable instead of intimidating.
8 minDifficulty 1
The Trial
Place a soft fruit or sealed sponge inside a reusable bag and mash its interior thoroughly without opening or tearing the outer bag.
Why it helps
You turn ambush grip into one concrete, visible experience instead of an abstract idea.
5 minDifficulty 3
The Trial
Configure one thing today explicitly for working alone, cautious and inconspicuous, rather than running a reduced version of the group setup.
Why it helps
Running a stripped-down version of the group setup alone means it fits badly and you feel diminished. A purpose-built solitary configuration works properly.
2 minDifficulty 2
The Trial
Warm one cup of whole milk in a microwave-safe jug in short bursts, or in a pan on an electric hob, until steaming but not boiling, then stir in a tablespoon of lemon juice or vinegar and leave it five minutes until curds form. Strain through a clean cloth or sieve over a bowl, keeping the whey.
Why it helps
Fresh cheese in fifteen minutes from one cup of milk.
15 minDifficulty 2
The Trial
Take one store you keep that has gone bad on you before - food at the back of a cupboard, saved files, clothes in a bag, leftovers. Before putting anything away today, do the preparation step that makes it keep: dry it, label it, portion it, cool it fully. Nothing goes into storage until that step is done.
Why it helps
Most of what you save is lost because you stored it wet, unlabelled or unportioned, and you pay for that in the lean week. The curing step costs minutes and saves the whole store.
2 minDifficulty 1
The Trial
Twist five pipe cleaners, or five rolled strips of kitchen foil, together at their middles into a ten-armed star, give at least five arms a fork by twisting on a short extra piece, and lay it open beside a mug to show it is wider than the rim. Curl every arm and fork tightly in toward the centre, without cutting, snapping or untwisting anything, until the whole star sits inside the mug below the rim.
Why it helps
A quiet, fiddly few minutes that ends in a satisfyingly tiny bundle.
12 minDifficulty 1
The Trial
Shape one tool or method today to the exact geometry of a specific obstacle rather than to a general class of them.
Why it helps
A general-purpose tool works adequately everywhere and reaches nothing sheltered for you. Shaping it to one exact geometry opens a layer nobody else can enter.
2 minDifficulty 2
The Trial
Instead of reusing your old setup for a new piece of work, make a fresh one today and deliberately leave the old one intact and available for someone else to use.
Why it helps
Overwriting your old setup saves you an hour and destroys the version someone else could have used. Leaving it intact costs almost nothing and quietly builds a stock of usable things.
2 minDifficulty 1
The Trial
Find a process you go through only because it is the designed route, and get the actual thing you need directly instead, legitimately: ask the person, request the extract, use the direct link. Skip the funnel once today.
Why it helps
Going through the designed route costs you the whole process to get one thing out of it. Asking directly is legitimate, takes a message, and usually gets you the thing the same day.
2 minDifficulty 2
The Trial
Identify the one inherited requirement that decides where or how you can work, and remove or replace it today rather than planning around it again.
Why it helps
One inherited requirement quietly decides everything about where and how you work, and you plan around it forever. Removing it once reopens options you stopped considering years ago.
2 minDifficulty 1
The Trial
Identify the two distinct operations hidden inside one task you keep failing at, and today use a different approach for each in sequence rather than one approach for both.
Why it helps
Using one approach for a task that is secretly two jobs is why it half-works on you every time. Naming the two and handling each properly usually fixes it first attempt.
2 minDifficulty 2
The Trial
Repair one visible break today before anything else, on the basis that the damage itself is advertising for more.
Why it helps
A visible break advertises itself and attracts more of the same to you. Repairing the first one before anything else stops the whole cascade.
2 minDifficulty 1
The Trial
Play one full song and perform it at maximum commitment as if you just walked onto a stage. Do not stop or restart once the song begins.
Why it helps
Pushes performance confidence, physical energy and willingness to look ridiculous for something memorable.
15 minDifficulty 4
The Trial
During a normal friendly moment, dance intensely for ten seconds with no announcement, then stop and continue exactly where you left off.
Why it helps
Ten seconds that a room does not see coming, and an immediate return to normal.
3 minDifficulty 3
The Trial
Reduce one search to no more than three unmistakable cues today, write them down, and search only on those rather than on judgement.
Why it helps
Searching on overall judgement means you miss things and cannot say why. Three written cues make the search fast and give you the same answer twice.
1 minDifficulty 4
The Trial
Give at least three consenting players a pale card each. Play ten quick rounds of rock-paper-scissors in rotating pairs, and after every win the winner shades one more square of their card with a dark marker; at the end, lay the cards side by side from palest to darkest.
Why it helps
A fast, fair little tournament with a scoreboard anyone can read.
15 minDifficulty 2
The Trial
Stand shoulder to shoulder with one or more partners, and lay each player's own colour of clothes pegs in their own sector on the floor straight ahead of their place in line. A random-interval timer app gives each signal: everyone darts straight out, grabs one of their own pegs and gets back into the same line; do five rounds within one minute.
Why it helps
A fast, cheerful group burst that gets everyone moving together.
3 minDifficulty 3
The Trial
Mark five cone, sock, or chair points in a tight indoor or yard course and run the path with a sharp cut at every point without stopping.
Why it helps
You train burst navigation that corrects course instead of relying on one perfect line.
6 minDifficulty 4
The Trial
Choose a cover spot you can step or crouch behind without going under anything, such as behind the sofa or round a doorframe, a few steps across a cleared floor from a start mark. Have a helper or a random-interval timer app sound three alarms at unpredictable moments within two minutes; each time, drop what you are doing and get behind cover.
Why it helps
A jolt of reaction speed and a cover spot you will remember.
4 minDifficulty 3
The Trial
Take something you have been repeating with no effect and say it once today at the hour when it will actually be heard: the quiet part of the day, the uncrowded channel.
Why it helps
Repeating something into a noisy hour is why nobody has registered it, and the repetition makes you look difficult. Saying it once when it is quiet usually lands.
2 minDifficulty 2
The Trial
Plan the vulnerable period after one change today, arrange to be somewhere protected for the whole of it, and state its expected length.
Why it helps
Treating a change as finished the moment you make it ignores the weeks afterwards when you cannot defend it. Planning that window is what stops the change being undone.
2 minDifficulty 2
The Trial
Take on one thing today large enough that the rest of your week is spent working it rather than looking for the next one.
Why it helps
Chasing many small things means your whole week is searching rather than working. One large enough thing turns searching into a rare event.
2 minDifficulty 1
The Trial
Make one commitment today that you know will take days to reverse, choosing it carefully, and then hold it without revisiting the decision.
Why it helps
Revisiting a slow-to-reverse decision daily means you pay the switching cost without ever getting the benefit. Choosing once and holding is the only way it pays.
2 minDifficulty 1
The Trial
Pick one escalation you will hold in reserve today, name what would trigger it, and then stay completely quiet unless that trigger happens.
Why it helps
Escalating early spends the move on something small and leaves you nothing later. Naming the trigger first means you stay quiet cheaply and the loud move still works when you need it.
2 minDifficulty 2
The Trial
Choose one bed edge, window box or row of potted plants in your own garden or pots, or with the owner's permission. Work along it from one end, stepping forward, picking off the faded flowers nearby and dropping them in a bowl, then moving on until you reach the other end.
Why it helps
A tidier border that keeps flowering for longer.
15 minDifficulty 2
The Trial
Set one thing today to a slow rate you could sustain for years, protect it passively, and remove the active effort you were putting into defending or accelerating it.
Why it helps
Running something at a rate you cannot sustain means stopping and losing the accumulated position. A rate you could hold for years gets further than any sprint you can manage.
2 minDifficulty 1
The Trial
Dedicate a small permanent part of your attention today purely to predicting where one thing will be, and act on the prediction.
Why it helps
Attention spread across everything leaves nothing predicting, so you always arrive late. A small dedicated slice is enough to put you ahead of it.
1 minDifficulty 4
The Trial
Separate today where you work from where you rest and commute between them on a schedule, rather than doing both in the same place.
Why it helps
Working and resting in the same place means neither ever happens properly and you feel on duty constantly. Two places and a schedule separates them without extra effort.
2 minDifficulty 2
The Trial
Replace one behavioural defence today with a coating or arrangement that needs no attention, and redirect the attention into output.
Why it helps
A defence that needs your attention takes it from your output every day. A coating that needs none means all of it goes into what you produce.
2 minDifficulty 1
The Trial
When something is challenged today, identify whether the structure or the contents is at stake and defend only the structure, conceding the contents if needed.
Why it helps
Fighting for this season's contents while the structure is taken means you win the argument and lose every year after. Defending the structure is the only version that lasts.
1 minDifficulty 3
The Trial
Do the one step today that only you can do, and make sure you cannot be displaced while doing it before you start.
Why it helps
Doing the step only you can do without securing your position means being displaced the moment it is open. Checking first is what keeps the value.
1 minDifficulty 4
The Trial
Instead of deepening what you are already best at today, make yourself adequate at one thing you currently cannot do at all, far enough to complete one real task with it.
Why it helps
Deepening what you are already good at has diminishing returns and leaves you fragile if that thing stops being wanted. Becoming adequate at one new thing changes what you can survive.
2 minDifficulty 2
