Infinite TicTacToe: Gomoku

Five in a row. One board. No second chances.

Infinite Tic-Tac-Toe takes the game you already know and blows it up: a 10x10 grid where you need five in a row, played as a best-of match against an AI that adapts to how well you are doing.

THE BOARD NEVER RESETS Every mark you place stays where it is. Round two starts on the mess round one left behind, and by the final round you are fighting over the last open lines on a crowded grid. Win a round and you score the length of the line you made, so a double line scores twice.

YOU ARE X OR O Your symbol is drawn at the start of every match. X is magenta and always moves first. O is cyan and answers. Your colour, your side of the screen and who opens all change from match to match.

MINES AND BOMBS Turn the mode on and each player gets one hidden mine and one visible bomb per round. Your mine is invisible to the AI until it steps on it, and then a 3x3 blast clears everything in the area. Bombs sit in the open counting down five turns where both of you can see them. Blasts chain off each other, so one bad tap can cascade across half the board.

SUDDEN DEATH In the final round each player gets 24 moves. Run out with no line on the board and the match ends in a draw.

AN AI THAT MOVES WITH YOU Adaptive difficulty steps the opponent up when you are winning and eases off when you are being beaten. Prefer a fixed fight? Lock it to Easy, Medium, Hard or Expert.

PICK YOUR LENGTH Quick is a single round, Sprint is three, Classic is five. One match runs one to five minutes.

COMPLETELY OFFLINE No account, no sign-up, no ads, no in-app purchases, and nothing about you is collected or sent anywhere. Play it on a plane.
