Four Pebbels

Four Pebbles provides players with an alternative option to the traditional Tic tac toe and offers a good amount of complexity, but it still retains the simplicity.

Rules:

The game involves 2 players placing their respective symbols in a 6x6 grid. The player who manages to place 4 of their symbols in a horizontal/vertical/diagonal row wins the game. If either player fails to do so, the game ends in a draw.

The players are allowed to switch their symbols after a certain amount of moves.

If a player chooses to swap his symbols with his opponent, they lose their current turn and the opponent gets to play again.
