Tic-tac-toe by Silverman
This version of tic-tac-toe is played on a 4x4 game board. This reminds people of a cross between roulette and Connect 4. One player uses X's and the other uses O's. Players move in turn, each placing their tokens on the board with his/her turn. 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. If four identical tokens appear on the upper-right to lower-left diagonal, this is not a winning position and the play continues. (This is the change we made to the original rules.)
Cram reminds of the paper game Tic-Tac-Toe. This game was named "Cram" - which means to jam or crush - because as the game progresses, there are less and less places for the stones on the board. At the beginning of the game the board is empty. 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.
To clarify, we will mark (using gray stones) the most disadvantageous places on the board. These spots are located next to the stone, and two places away from the stone in all eight directions.
There are some 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! Does betting favor the person who goes first or second? That depends on the way you play.
