This application solves the game of Four in a Row (classic Connect 4). The solver can evaluate and report the theoretical game ending result of all moves available to a player for any legal game board position. Users, or the solver, can then choose moves to play.

This solver version can also interactively play the game with "perfect" artificial intelligence. Winning is not possible when the solver plays as 1st player, and extremely difficult when the solver plays as 2nd player.

The game board permits adding, rolling back, and rolling forward moves for either player, at any time. The solver can run on any turn. These controls are helpful for finding game changing moves, checking alternate moves, or for cheating, with an in-progress or already completed game.

Four in a Row Solver trial version is fully functional, but may require several hours to evaluate game boards with fewer than ten pieces. The full version utilizes a database of opening game positions for this task.

    Really neat. The app knows how the game ends, if you ask, even before the 1st move. Perfect tool to gain an unfair advantage when you're playing against other Connect Four apps, online opponents, and opponents in person. The AI is invincible, and it tells you so, so it wasn't so much fun trying to defeat it.
