Connect four or more same colored gems on your board. One leftover "Free Fall" gem will glow with a circle around it. Based on where you connect it with other pieces, it will clear either a row or column. Examine a "Free Fall" gem's light to learn how it will change the level. If its light slides horizontally, it will eliminate a row of gems. If the light slides vertically, it will eliminate a column. Create a "T" or "L" shaped combo to activate special powers to help you throughout various levels. Always match as many tiles as possible for additional bonuses and extra powers. Match five gems to create an explosion. A "cracked" gem will appear, which when matched with at least two gems of the same color will explode and may may set off a chain reaction.
