4-In-A-Row Solver

Drop your chips, line up four, and try to outthink an AI that can see how the game ends before you do. 4-In-A-Row Solver pairs the classic game with a real solver. On Hard it searches deep into every position, plays perfectly as the board fills up, and tells you the moment it has a forced win, or when you do. FEATURES • Three difficulty levels: Easy for a relaxed game, Medium for a fair fight, Hard for a real challenge • Hints that show your best move and whether it wins, draws or just holds on longest • Forced-win alerts that tell you exactly how many moves until the game is decided • Undo your last move and try a different idea • Go first as Red, or let the AI open as Yellow • A clean glass design with smooth chip drops and haptic feedback • Plays on iPhone, iPad and Mac, with keyboard shortcuts on Mac (1–7 to drop a chip, ⌘Z to undo) • VoiceOver support for every column • No ads, no accounts, works offline
