Hexa GO! is a logic puzzle game that tasks the player with sorting and removing hexagon-shaped tiles from pavers arranged into grids of different shapes and sizes. The player's main objective is to unlock and play every level of the game.
Each grid displays two or more tiles marked with white directional arrows. When the player selects an unblocked tile, the game auto-flips it in its arrow's direction along a straight path until it falls through a hole in the pattern or off one of the edges.
Over time, the player reveals hidden features, such as a hammer that removes a tile, a bomb that causes an explosive force that knocks tiles off the grid, a double-arrow paver that allows a tile to turn left or right, and a green swap tool that changes the positions of adjacent tiles. The game limits the player's moves or time. With moves, it counts any selection against the total number, including when the player accidentally selects a blocked tile or uses a special feature.
Hexa GO! unlocks fun side games when the player reaches levels 15, 50, and 75. For example, the player can play a tournament mode that counts every win toward a global ranking position. They can also access a paint game that allows them to use the tiles they win at the end of each level to paint pictures on framed canvases.
