Four Stack
Drop your discs and connect four before the AI outsmarts you!
How to play
Take turns dropping discs into the grid — line up four of yours in any direction to win. The AI looks further ahead with every stage, blocking your threats and building sneaky double attacks of its own. Your progress is saved automatically, so you can come back and continue from the highest stage you have unlocked.
