About game
Place your marks strategically to outsmart your opponent in this modern evolution of a timeless classic. You win by aligning symbols across diverse grid sizes or clearing rows in the creative new Linetris mode. Vanishing Tic-Tac-Toe changes everything because your oldest pieces disappear after a few turns, forcing you to rethink your standard tactics. Four in a row fans will appreciate the gravity mechanic where pieces drop to the bottom of the column. Every match pushes you to calculate moves ahead of the computer or your friends. Switch between different board sizes to keep your brain sharp and test your logic skills. This web-based experience runs directly in your browser without any annoying downloads or registrations. Jump into a match right now to see how many lines you can clear.
How to play
The game is played via screen taps on both PC and mobile devices.
Your goal is to form a line of a certain length (depending on the mode) vertically, horizontally, or diagonally to defeat your opponent.
Choose your game mode:
Classic Mode — the first player to align three (3x3), four (4x4), or five (5x5) pieces vertically, horizontally, or diagonally wins.
Vanishing Tic-Tac-Toe — once a player places their fourth (3x3) or fifth (4x4) symbol, their oldest symbol automatically disappears, freeing up the cell.
4-in-a-row Mode — players take turns placing marks in any of the seven columns. The mark ""falls"" to the lowest available empty cell in the column.
Linetris — if the bottom row is completely filled, all marks in that row disappear, and the rest of the board shifts down by one row.
