4 In A Row: Classic is a strategy-predictive game that simulates Milton Bradley's (now Hasbro) classic Connect Four. The player must create a horizontal, vertical or diagonal line made from four matching colored disk-shaped pieces or tokens before the game's AI or another player in one-player or two-player modes, respectively.
The player starts the game by selecting a mode. They then choose a level of difficulty, with 3 being the most difficult option, and the red or blue pieces. The first player drops their first piece down one of seven grid columns across six rows by selecting a column. The piece drops vertically down the grid and stops on the first row. Their opponent then drops a piece. The two players take turns dropping pieces to try to create a four-piece row first and block their opponent's moves.
As with Connect Four, 4 In A Row: Classic is defined as a strategy-predictive or solved game because the player who goes first can win every time they play if they accurately predict their opponent's strategy and moves. That said, if both players can accurately predict each other's moves, then the game usually ends in a draw or stalemate with no more moves possible for either player.
The game displays the winner and loser on a step-style raised platform, along with the amount of time the player or players took to reach the end of the game.
