Players share a pool of identical dice, each face of which shows a component of a Celtic knot work design. Each player starts with one die placed in their design. On each turn a player rolls one dice for each player, and adds one of those dice to each player's design. Designs are constrained to fit inside a 5x5 grid. When no more dice can be placed the game ends, and the player who has the single longest path with the most crossings wins.
