Each player is assigned a color of blobs. The winner is the player with the most blobs at the end of the game. The game ends when every player can no longer play.

Each turn the player can move a blob to an near empty square. If the blob is moved to an adjacent square, the blob is duplicated.

The blob can also be moved one square away in all direction. In this case, the blob just teleports to its new position. To prevent foul play, if after 20 consecutive moves no blob is duplicated, the game ends and the player with the most blobs win.

When a blob is duplicated or teleports itself, the blobs of the opponent adjacent to the new blob position become the player blobs.
