Castling: Tower Defense is a unique strategy game that combines the classic elements of chess with the engaging mechanics of tower defense. Players strategically place chess pieces on an 8x8 board to form a defensive line against waves of enemies. Each chess piece, including Pawns, Knights, Bishops, Rooks, and Queens, behaves according to its traditional chess movements, adding a layer of tactical depth to the gameplay. The objective is to protect the King from relentless assaults, requiring careful planning and execution.

In Castling, players can freely arrange their pieces during the placement phase before initiating the defense phase, where the pieces automatically engage the enemies. The game encourages players to block enemy paths, utilize traps, and manage resources effectively to upgrade their defenses. With epic boss battles and the ability to create powerful synergies among pieces, Castling offers a challenging and strategic gaming experience for fans of both chess and tower defense genres.
