Tic Tac Toe Glow

A luminous board replaces paper in Tic Tac Toe Glow. The instructions name three-by-three and five-by-five grids, with three or four marks in a row as the winning alignment. Horizontal, vertical and diagonal lines all count, so you need to inspect more than one direction before placing a mark.

Tic Tac Toe Glow provides rules without any actual input bindings. Controls are shown in-game, including how to select a square; no mouse button, touch gesture or keyboard shortcut can be confirmed from the supplied instruction field.

Your mark is X and the opponent's is O. The source says the game ends when all squares are filled, but it does not explicitly map each board size to one of the line targets or describe human-versus-computer options. Check the selected board's rules rather than assuming every setting follows the same match format.

Check for an immediate threat before building a longer plan. A larger board can make a diagonal line easier to overlook, and confirming whether the current setting needs three or four marks keeps your placement decisions tied to the displayed winning condition. Another tic-tac-toe version with different board sizes is Tic Tac Toe Mania.
