Drag the tiles horizontally to make the shapes match
There are 4 adjacent stacks of tiles, that must be reordered by sliding them into another column left or right, in order to fit the hole above. The topmost tile is always used when sliding, and tiles fall over instantly after moving to a column. tiles do not skip a column. Sucessfully fitting the tiles into the hole scores a point, and starts the timer, progessively going faster each time a point is scored. The game ends once the timer runs out. There are numerous different palettes the game offers for each point. If it appears to be distracting, the player can tap on the screen at the beginning to switch between a single, monochrome palette and the colorful, randomised palette.
