This minigame borrows its idea from Popgames' "Bejeweled" in which the player has to match three or more gems on a table filled with different colored gems. Once three or more gems have been alligned, the gems are crushed, allowing new gems to enter the table. In Crystal Story II, the player must destroy gems in order to damage and kill a monster king as he sends his minions towards you. The minigame ends when either the enemy's health bar is depleted, or one of his minions reaches you. There is no penalty for losing the mini-game.

This is the last minigame the player will encounter in Crystal Story II. The objective of the minigame is to reach the bottom of a slope. If certain time limits are met, the player is awarded a medal and an item corresponding to the medal. Note that the medal can only be awarded once as well as the item.
Getting gold in Snowboard Extreme's third track unlocks the achievement "Snowboard Extreme" and rewards a Ruby.
