It is a fine app, but it is annoying that there is no time control and some players would stop playing the game if they find themselves in a bad game! Some time limit would be appreciated!
If you accidentally hit pass, you are doomed. And it is right next to “OK” and the corner of the board. If you hit it, you don’t get any more turns, even if you have moves available.
The iPad implementation for the famous board game Blokus. Supports 2 players and 4 players. Originally programmed in 2017. Rules: Touch a block to select it, then drag to place it on board. Each block should share a corner (but cannot share an edge) with an existing block of the same color, except for the first block, which should cover the dot of the same color. A block may not overlap with any other blocks. When you cannot place any more blocks, tap "PASS". Google "Blokus" for a more detailed introduction.
