Tic Tac Toe

Tic Tac Toe — a logic game between two opponents on a square field 3x3 cells. Each player has a "tic", the second — "tac". Players take turns putting on free squares 3x3 field marks (one always tics, another always toes). First, rank your 3 pieces vertically, horizontally or diagonally — wins. The first move is made by the player tic.
