Officers' Skat choose trumps once both players have four cards, face up, before them. If both players pass, the game is played as "Ramsch", i.e. the is to get the lowest score. The feature of Harlequin Skat is the fact that a player only sees half his own cards, but also half of his opponent's. His opponent cannot see any of those cards, but can see all the others. The advantages of harlequin skat are that you need less space to play it, and a greater tactical depth because you know your opponent's cards before they are seen. The same rules apply
Games played with Go equipment It's also possible to use Go equipment as a low-tech interface to Conway's Game of Life; use black stones in the board's squares as 'pixels', and for each generation use white stones to indicate where new cells will be born. Then remove 'dead' black stones, replace the white stones with black ones to complete the new generation, and repeat the process. Games played with Go equipment Many games can be played with Go equipment: a supply of white and black "stones" and a board with 19×19 intersections, other than Go and many more can be played with minor modification.
