The board is alive
A lone cell dies whoever painted it; a 2×2 block lives forever. What survives is not what you painted — it is what your pattern grew into. Anyone may advance the world.

This round
Paint a few cells
Press start, pick a colour, drag across the grid. Five charges at a time, one back every three minutes. A handful of cells costs a few cents in gas — nothing else.
Fight over it
Anyone can paint over anyone. Overwriting costs less gas than filling an empty cell, so holding ground is cheaper than taking it. Nobody takes the board in one move — five cells, then you wait.
Watch the clock
The board locks for the final ten minutes, then the picture is fixed for good. The contract renders it for anyone who asks, long after this page is gone.
Why it costs almost nothing
Cells are packed 32 to a storage slot, so painting a contiguous patch is barely more expensive than painting one cell. Submitting five at once works out around a cent each; clicking them one at a time costs six times more. Select a patch, then submit.
What the contract can and cannot do
It is not payable — it cannot receive ETH. It has no transfers and no approvals, and its bytecode contains no CALL, DELEGATECALL or SELFDESTRUCT. It is not upgradeable and no admin can alter the canvas, the clock, or any parameter.
Connecting a wallet only ever asks you to sign a paint transaction. Read it yourself — the whole thing is about a hundred lines.
Where the picture lives
Every cell, every colour and every stroke is stored on Robinhood Chain, not on a server. Anyone can replay how the picture was made, block by block, long after this page is gone.
Every board
Boards deployed through the factory land in an on-chain registry. Nothing here is served from a database — the list, the clocks and the pictures all come out of contract state.
Run a board for your community
Your size, your clock, your charge rules. You become its curator; the factory keeps no power over what it creates and takes no fee. You pay the deploy gas — about a dollar — and painters pay their own cents.
