Collect adjacent colored dots along a route. Each level presents a series of color targets. Starting from the beginning, players can only click on adjacent colored dots in the order of up, down, left, and right to collect them and pass the level. Clicking the wrong dot or clicking too far away will deduct moves. Passing a level unlocks the next level. There are 88 levels in total. The homepage features a spiral level board, and the names are not displayed in the app.
