EinStein würfelt nicht!

(Einstein/"OneStone" does not play dice) is a board game, designed by Ingo Althöfer, a professor of applied mathematics in Jena, Germany.

During setup, players arrange the cubes within the triangular area of their own color.

The players take turns rolling a six-sided die and then moving the matching cube.

The player starting in the top-left may move that cube one square to the right, down, or on the diagonal down and to the right; the player starting in the bottom-right may move that cube one square to the left, up, or on the diagonal up and to the left.

The game can also be played on a 6 × 6 board with ten pieces on each side, labeled 2, 3, 4, 5, 6, 8, 9, 10, 11, and 12.
