About GraveSun

Grave Sun is a vertical mahjong tower defence mobile game that combines four-lane defensive setups with automatic shooting gameplay. Players control mahjong tile towers guarded by golden dragons, sliding up and down to switch attack lanes while the towers automatically target and fire golden spirit bullets to repel the incoming evil tiles. Defeating enemies earns points, which can be spent to upgrade tower firepower and unlock stronger attacks like homing bullets and area explosions. As scores increase, enemy waves become denser and faster, and mutated units like split evil tiles appear. With simple controls and a fast pace, it’s perfect for quick sessions but also challenges players on lane choices and upgrade timing, constantly pushing for a higher record in the endurance defense battles.
