I took a nap and dreamed I was playing a game. When I woke up, I remembered all of the rules. So I wrote them down:
Components:
a chess/checker board
six "Pip" d6 (player one)
six "Number" d6 (player two)
Goal:
accumulate points by capturing your opponent's dice
Setup:
Player one puts a die in one corner of the board, showing 1.
Player two puts a die in the opposite board corner, showing 1.
Players alternate placing dice until all the dice are placed.
Dice must be placed orthogonally adjacent to another die owned by the same player.
At the end of the setup, each player must have one die on each face.
Play:
One move per turn.
A player may:
-move a die any number of spaces in a straight orthogonal line, dice may not move through or share space with another die
-capture an opponent's die by moving a die of an equal or greater value into that die's space, after capturing an opponent, the die is rotated to the next highest value, a "six" is rotated to a "one"
-rotate a die to the next higher value, six may not rotate higher
-rotate a die to the next lower value, one may not rotate lower
Scoring:
When a die is captured, score points equal to the showing value.
Endgame:
The game ends when one player has lost all of their dice or when each player only has one die left.
Tally the score!
There is every possibility that I'm remembering another game, so if this rings a bell with someone, speak up!
