Amoeba

Board & Pieces
Each player has ten standard pieces and one Kernel piece on a hex board.

Movements
Players take turns to move a piece of their own color. No pass is allowed.
Pieces move as a single piece or stacked multiple pieces (=stacks). Stacks are controlled by the player who plays the color on the top of them.
Stacks move all together or split into single pieces as they move. Moves are restricted to directly straight, no change of directions in the same move allowed.
Kernels move exactly as other pieces. Kernels do not have to be on the top of stacks.

Goal
The game is won by the player who first controls the stack with the enemy Kernel or who takes all the legitimate moves away from the other player.
