How to Play
One random piece at a time (70% pentomino, 20% tetromino, 10% tromino). Your next 3 pieces are shown ahead.
Enclose a pocket of 4 or fewer empty squares to clear it and free the space.
Clear the whole board to finish. Fastest times make the leaderboard.
No legal placement for your current piece ends the run early.
10×10 board, one random piece at a time, no preview.
Pieces never disappear. Any fully enclosed pocket counts as captured territory, no matter the size.
Goal is the opposite of a real match: keep captured territory as low as possible.
Run ends when your piece has no legal spot. Lowest captured wins.
Same rules as Eogonim, but placed pieces vanish from view instantly.
They still occupy their squares. Remember where you put them.
You'll never get the same shape twice in a row.
Clicking an occupied square ends your run immediately.
The board reveals fully once your run ends.
10×10 board, played in rounds. Pick 1 of 3 shapes to start, with unlimited supply.
Capturing works like Eogonim: no removal, any pocket size counts.
Each round has a rising target (10, then 15, then 18, +2 after that).
Clear it to unlock a new shape and reset the board. Miss it and the run ends. Score is rounds cleared.
10×10 board, one random piece at a time, no preview. Starts with 5 dead squares already on the board.
One more square dies (at random, never inside territory you've already captured) after every piece you place.
Dead squares can't be placed on, and they poison capturing - a pocket bordering one never counts, even if your own pieces surround the rest of it.
Run ends when your piece has no legal spot. Highest captured wins.
12×12 board, a real hand (7 pentominoes, 2 tetrominoes, 1 tromino) - place them one at a time like a real match.
The bot can place any piece at all, unlimited supply, and territory is scored the same way a real match's is.
Every bot turn, after its own move, it gets exactly one bonus action: goes again, deletes one of your pieces, blights one of your territories, or rerolls your hand.
Run ends once you have no legal placement left. Score is your territory minus the bot's - negative is common.
10×10 board, one random piece at a time, no preview, nothing ever disappears - Eogonim's own engine.
Every piece is dealt one random curse: locked orientation, can't touch the border, invisible while placing, or a blight spot spreads after you place it.
A curse that would leave the piece completely unplaceable is never dealt.
Clicking an occupied square ends your run immediately. Score is however many squares are still empty or blighted when you get stuck - lower is better.
10×10 board, one random piece at a time, no preview, nothing ever disappears.
Every 4th piece you place, the border shrinks in by one ring on every side. Voided cells can never be placed on again.
Only a placed piece is ever safe - any still-open square caught by the shrink is swallowed along with it.
Run ends when your piece has no legal spot. Score is squares never filled by a piece (open or voided, out of 100) - lower is better. A perfect 0 is impossible.
12×12 board, one random piece at a time, no preview, nothing ever disappears.
Pieces range from a 3-block tromino up to a full 7-block heptomino (no monominoes or dominoes) - bigger sizes are drawn far more often than small ones (weighted by size, so a heptomino is more than 2x as likely as a tromino), then a random shape of that size is drawn.
Run ends when your piece has no legal spot, or the board fills completely. Score is squares never filled by a piece (out of 144) - lower is better. Unlike Shrink, a perfect 0 is possible.
12×12 board, a real hand (7 pentominoes, 2 tetrominoes, 1 tromino) dealt all at once, same as GodBot's.
Instead of a plain empty board, a custom shape is generated that exactly fits your hand - every non-void square can be filled, with nothing left over. The shape can be one connected blob or several separate pockets.
Placements aren't final - click a piece you've already placed to send it back to your hand and try a different spot or orientation.
Clear 3 boards in a row (a fresh hand and shape each time) as fast as you can - your total time across all 3 is what gets saved to the leaderboard. Lower is better.
