Bejeweled Stars, formerly known as Bejeweled Skies, is the third spinoff of the Bejeweled series by PopCap Games. The game was soft-released to Canada on December 2015, and entered a wider release in select countries worldwide on May 2016.
Unlike previous games in the series, Bejeweled Stars is centered around the completion of levels. Once the player has completed one level, the next one is unlocked. Each level has its own objective, and some levels introduce the player to various game mechanics such as currents, clouds, Special Gems and further unique goals. The game also introduces Powers (similar to Boosts) and SkyGems, the latter of which are used to create Powers and items in the Power Lab.
