Easy Gold Crowns - The fastest way to complete the mini-games in the album is to finish them with the exact points needed; you do not need to complete all the levels to do that. For example, when you need to get 20 points do the following. Save your four lives and complete level 16. Then, intentionally die. Since you still have four lives, they will be spent completing levels 17, 18, 19, and 20. This happens because even if you die the level will be considered as completed. Obviously if you accidentally die once before reaching level 16 (in this example), you must complete level 17; if you die twice you must complete level 18, etc. This can also be performed at any time you need points. Just complete the level that stays four levels before the level you want to reach.
