Mr. Estrada's Cell Repair

Grow your cell team, collect nutrients, and get ready to repair an injury. Every new cell must come from a cell you already have.

Set up a match

Choose 2–4 cell teams

Choose how many teams will play, then start.

Set up your teams

Choose 2–4 teams. Give each a name and choose Human or Computer. Computer teams follow the same rules and cannot see hidden squares.

How to play

Choose one of your cells, then an empty square directly beside it. The cell divides.
Your turn changes automatically after a division. Each team normally gets one division per generation. A new cell waits until the next generation to divide.
Yellow nutrients or a hidden boost may earn an extra division. A used boost square turns green and keeps its cell. If no cell is ready, you keep that bonus for your next turn.
Four hidden infection squares are mixed into the board. Landing on one removes only that new cell. Once revealed, the square stays blocked. Blue low-resource squares make a new cell wait one extra generation.
At the start of Generation 8, an injury clears the pink area. Grow into those squares afterward to repair it. A filled injury square turns green.
The match lasts up to 20 generations. Score 1 per surviving cell and 2 extra per repaired square.

Nutrients: extra division Revealed boost: extra division Low resources: longer wait Barrier: blocked Open injury Repaired square Hidden boost or infection

This is a simplified model. Real tissues do not compete in teams, and different kinds of cells divide at different rates. Infection is a chance event in this game, not a prediction of where a real virus would be.

Keyboard: focus the board, use arrow keys to move, and press Enter to select.

For the science discussion

What was the parent of your newest cell? Did getting to a nutrient square help? Why might it be useful for cells near an injury to divide? Which game rule is a simplification of real biology?
