Rules summary
Overview
Win 3 regions of Tic-Tac-Toe games in a line on a 3x3 grid of Tic-Tac-Toe games.
Gameplay
Red (o) starts by placing a red (o) token anywhere on the 9 regions.
The area on the local region just played determines where the next player will play e.g. place on the central area on any region and the opponent will play on the central region next.
Three in a line of area wins the region.
If a region is won, when that area is played on another region, the opponent gets to play anywhere e.g. central region has been won by red (o), the current player plays in a central area on an outer region, so the opponent can pick any free area anywhere.
Three in a line of regions wins the game.
Tiebreaker
In case nobody is able to finish a line of regions, the player with the more won regions wins the game.
Board sizes
Play on a 4x4 or 5x5 board. More regions and more areas inside them.
On 4x4 and 5x5 board sizes, lines do not win a region or a game. Only 2x2 blocks count.
Advanced mode
Win 5 regions to win the game. Normal line condition doesn't win. This rule changes to 8 on a 4x4 board or 13 on a 5x5 board.
Inverse game
The victory conditions are reversed. You win if your opponent satisfies the usual winning condition.
Different winning conditions
Win the game with the original Tic-Tac-Toe lines or with producing 2x2 squares. This option is only available on 4x4 and 5x5 boards.
