Four in Zone

The game uses a standard 7-column× 6-row vertical chessboard. Players and AI take turns to throw the pieces into any column, and the pieces automatically fall to the empty space at the bottom of the column. The first person to connect four pieces of the same color in the horizontal, vertical or arbitrary diagonal direction wins. Built-in AI is implemented based on Minimax algorithm, with a search depth of 5 layers, which can predict the situation changes after multiple steps and provide a challenging and fair game experience. When winning, the system will highlight the four pieces that make up the connection line, clearly showing the winning path. The rules are simple and easy to understand, and the strategies are profound and changeable-seize the central control or set a diagonal trap? Every step tests your foresight and layout ability. In "Four in Zone", the outcome is often only between one son, and wisdom always comes first.
