I've just released a fresh new game in the spirit of Tetris, Cirix 2. It is available for free at: https://www.hugi.scene.org/adok/miscellaneous/cirix2.zip Both Cirix and Cirix 2 are similar to Tetris, but not quite the same. While the first Cirix game was for three players, Cirix 2 is for a solo player and thus more accessible. In the first game each player threw a block at one time into the game and they had to see to it that four or more blocks get placed adjacently to each other so that they would be cleared. By contrast, the second game works with three blocks at once, and each block has a number on it that signifies the number of blocks that have to be adjacent to each other so that they will be cleared. I think it's a fine recreational game, just like the original Tetris.
