About this game

Players take turns drawing edges between adjacent dots on a grid. Complete the fourth side of a square to claim it and earn another turn. The player with the most claimed squares wins. Choose small, medium or large grids for shorter or longer matches. Three AI difficulty levels — Easy, Normal, Hard — control how many moves the AI looks ahead. Box chain reactions can flip the game instantly.
