About these board games
Playing against the computer means you never wait for an opponent: open the page and the first move is yours. The AI uses the minimax algorithm, the same idea behind classic chess programs, which looks ahead at possible moves and picks the one that leaves you with the fewest chances. On Easy it makes deliberate mistakes so beginners can learn; on Hard it punishes every loose disc. Track your longest winning streak and try to keep it alive across difficulty levels.
- Four in a Row: Play Four in a Row against the computer on three difficulty levels. Line up four discs before the AI does. Free, no sign-up, mobile and PC.
