Dominup is a game for 2 to 4 players that can be played with a Double-seven binary-coding dominoes set (36 tiles) or a standard Dominoes set. There are two types of placements in Dominup. In both cases the tile must be aligned with an imaginary orthogonal grid: ‘Climb’ placement: The tile is placed atop two adjacent tiles of the same level, so that the numbers (symbols) of the placed tile match the symbols underneath (one of each supporting tile). ‘Expand’ placement: The tile is placed on the table and orthogonally adjacent to at least one tile already placed. Randomly distribute the tiles face-down among the players (as in dominoes). The player with the double-7 starts by placing it in the middle of the playing surface. Starting with the second player, players take turns in anticlockwise order doing all of the following steps in order until the game end condition is reached: 1. If you can make a climb placement with at least one of your tiles, then you must do so. You can choose which tile to place, as long as the placement is legal. Repeat this action until you can’t make any more climb placements. 2. If you have at least one tile left, then make one expand placement. If, at the end of your turn, you have no tiles left, then you’ve won and the game ends. However, the other players can continue playing to determine 2nd, 3rd, and 4th place if they wish. Variant: Misere Dominup In this variant, the player who runs out of tiles first loses.
