Move and jump to make a 4 in-a-row or stalemate the adversary in this 2-player abstract game.
Equipment:
* a 5x5 board
* About 10 stones in 2 different colors, or 10 reversible pieces (like in Reversi/Othello)
Each player starts with 5 pieces of his color (or 5 Revesri/Othello pieces). The game begins with each player dropping one of his stones per turn on an empty cell. After that, on each turn, each player must do one of the following actions: 1) Use a friendly stone to jump (orthogonally or diagonally) over an enemy stone landing on the immediate empty cell and flipping the color of the jumped stone (black turns white, and vice versa). Jumps are multiple (the player may choose between choices) and mandatory -- or 2) Move a friendly stone to an (orthogonal or diagonal) adjacent empty cell.
The player that either makes an (orthogonal or diagonal) 5 in-a-row or stalemates his opponent wins.
