Cephalopod is a game played with dice on a 5x5 board. Each turn, a player places a die on an empty cell. If there are two or more dice in horizontally or vertically adjacent cells whose pips add up to 6 or less, the player must capture two or more of those dice. When dice are captured, they are removed from the board, and a new die is added whose pips are the sum of the captured dice. To make a capturing move, first click on the empty cell you want to place your die, then click on the (2 or more) adjacent dice to capture; finally click on the empty cell again. Both your and your opponents dice can be captured. If the cell where you're placing your die has no captures possible (because there are zero or one adjacent dice, or they add up to more than 6), the die is placed on the board with 1 pip. The game is over when the board is full, and the player with the most dice on the board wins. (Note that the pips on the dice don't matter for determining the winner, just the total number of dice).

Cephalopod was created by Mark Steere, and more detailed instructions are available here.


By placing a die on the highlighted empty cell, player 1 can capture the blue 1 and 5 dice, resulting in a red 6 that can't be captured.
