3 logic games. Each game has 4 levels of difficulty. Tic-tac-toe is played on a 4x4 game board. One player uses X's and the other uses O's. Players move in turn, each placing their tokens on the board. If a row of four identical tokens (either X's or O's) appears somewhere on the board - horizontally, vertically or on the upper-left to lower-right diagonal - the player who started the game wins. Otherwise the second player wins.
Cram will remind you of the game Tic-tac-toe but is played on a 8x8 game field. The players move in turn, putting designated stones on any vacant space. The object of the game is to create a line of three stones horizontally, vertically, or diagonally. With that, your stones and your opponent's stones are counted.
In the game Super Nim there are randomly placed pieces on the board when the game begins. The players in turn remove all of the pieces from one selected column or row. If you are the player to remove the very last piece, you win!
