The following power-ups are available.

Glacier
Match five gems of the same color in a row. A Glacier can be combined with others of its same type to destroy all gems in the level of the same color you matched it with.

Iceberg
Match colors in a "T" or "L" shape. An Iceberg is a gem with a snowflake surrounding it. Match the Iceberg to ignite its fuse, and it will explode and eliminate any gem next to it.

Windchill
Match four gems of the same color in a row. A Windchill is an extra shiny gem that when matched with another gem, will explode and destroy that column or row.

Swipe a power-up and place it on another power-up to create a more powerful effect. For example, combining a Windchill and an Iceberg will cause it to eliminate several rows of gems at once. Use power-ups whenever they are available.
