Hottest free Mac OSX "tile-based" games

Tile-based movement is a gameplay system where characters or units move across a grid made up of uniform squares or tiles. Each tile represents a discrete space, and movement is typically limited to adjacent tiles, either orthogonally or diagonally. This system simplifies map design, collision detection, and player navigation, making it especially common in early RPGs, dungeon crawlers, and tactics games. Tile-based movement creates a structured, puzzle-like feel where positioning and planning are key.
