UnTile
UnTile is a relaxing ant colony puzzle in the family of Colony Flow: crews of tiny worker ants take a pixel art picture apart tile by tile. You decide which crew marches when — and with only five stands to work from, order is everything.
In 2026 ant colony puzzles marched straight up the mobile charts — Colony Flow! alone picked up half a million downloads and a 4.5-star crowd within weeks of launch. The recipe is instantly charming: a pixel art picture built from colored cubes, queues of busy worker ants, and a simple tap that sends a crew off to do its job. UnTile brings that recipe to the browser — free, no download, no sign-up, one click and the colony gets to work.
Every box in the queue holds a crew of ants of one color. Tap the front box of a column and it takes one of five stands; its ants run to the picture, trot around the edge and dive straight in. Here is the puzzle: an ant can only carry off a tile with a clear straight line to the picture's edge, so the picture peels from the outside in, and the order you send the crews decides everything. Send a color that is still buried and the box just stands there waiting, holding a stand hostage — when all five stands are stuck waiting, the colony grinds to a halt and the level is lost. There is no timer and nothing to dodge; the only pressure is the order of your own taps.
Behind the ants there is a lot to uncover: over 260 hand-picked pixel art pictures — animals, food, characters, little scenes and kaleidoscope patterns — each level carrying its own palette. Later levels add linked boxes that only march as a pair, and hidden colors that stay invisible until you clear the tiles around them. Lives refill on their own — one every half hour — and coins earned from wins can buy an instant retry, so a lost level never costs more than a short break.
How to play UnTile
Send the right ants at the right time:
- Tap the front box of any queue — it moves to a free stand and its ants start marching.
- Ants carry off tiles of their own color, but only tiles with a clear straight line to the picture's edge.
- Peel the picture from the outside in: clearing outer tiles opens the ones hiding behind them.
- A crew whose color is buried waits on its stand — don't let all five stands jam up with waiting boxes, that is the one way to lose.
- Carry off every tile to clear the picture and move on to the next one.
Tips for UnTile
- Before every tap, check which tiles of that color are actually reachable — a clear straight ray to the edge is the whole game.
- Keep at least one stand free: a spare slot is the difference between a jam and a comeback.
- Peel evenly. Stripping one side down to the core buries the colors your next queues will need.
- Linked boxes march as a pair and hold their stands until both are empty — make sure there is work for both colors before you commit.
- A hidden color hides under its neighbours: clear the tiles around it and it will show itself.

Frequently asked questions
Is UnTile free to play?
Yes. UnTile is free on crokocat with no download and no sign-up — it runs entirely in your browser, on desktop, phone or tablet.
Which tiles can the ants take?
Only tiles with a clear straight line to the picture's edge — if anything stands between a tile and open air, the ants can't reach it yet. Clear the outer tiles first and the inner ones open up.
Why is my box just sitting on its stand?
Its color is still buried, so the crew waits until you uncover it. Waiting boxes hold their stands — if all five stands fill up with waiting crews, the level is lost, so watch what you send.
How do lives and coins work?
You have five lives and a lost level costs one; lives refill on their own, one every half hour. Wins pay out coins, and coins can buy an instant retry of a lost level — everything is saved on your device.
