Based on the bonus levels in the original Super Collapse!, but without time
limits, in each level in Puzzle Gallery you will be asked to clear all tiles
from the board. You can only remove groups of three or more tiles, however,
which is where the difficulty comes in. The 300 individually-designed levels
will test your ingenuity, and come in difficulties ranging from very easy to
only mostly impossible. As an incentive to do well, the game tracks the number
of turns you take, and gives you a “Puzzle Genius” award if you solve the
puzzle in the minimum amount of moves. Finally, a hint feature is available if
you need help. The puzzles are selectable from a gallery, and any puzzle can
be replayed.
