Choose Two players, then take turns tapping an empty square on the same device, each player with their own mark. The first to get three marks in a row, across, down or corner to corner, wins. If all nine squares fill with no row, it is a draw. Nothing needs signing up for and nothing is saved.
No. If both players make the best move every turn, tic-tac-toe always ends in a draw. The player who goes first can win only when the other player makes a mistake. That is why the Clever setting here never loses and often draws: it plays perfectly.
Going first is a small advantage, because the first player can start in the center or a corner. In this game you go first against Mathumo, and the starter switches each time you play again so both sides get a turn.
A corner or the center. Both keep the most winning rows open. Starting on an edge square gives the other player an easier time. A good rule for beginners: take the center if you can, then a corner.
Many children can play from about age 4 or 5, once they can take turns and spot three marks in a line. The one-move puzzles, “Can you win next?” and “Can you stop a win?”, help children learn to look at the whole board before choosing a square.
