TileWave fills a six by six grid with coloured tiles cycling through four colours — coral, rose, violet and teal. Tap anywhere on the grid to drop a wave from that point. The wave spreads outward across every tile on the grid and flips each one forward one step in the colour cycle. The tile you tap directly at the epicentre flips twice. Tap again in a different position and the new wave interacts with the result of your previous tap. Tiles that receive flips from overlapping wave patterns shift further around the colour cycle. The goal of each level is to make every tile on the grid the same colour. The levels are built by working backwards from a solved position so every puzzle has a known solution. How efficiently you find it determines your score. Later levels require more waves and more careful planning to align all thirty-six tiles. A colour distribution bar below the grid shows how many tiles remain in each colour so you can track your progress at a glance.
