Use any means necessary to complete the first 100 single player levels out of the 285 total levels.
Always shoot for high scores. Here are things that help:
- Make and use power crystals (windchill, iceberg, glacier)
- Finish levels with lots of moves left
- Combo moves and cascades (side-by-side matches & matches that occur immediately after your initial match)
- Speed multipliers (make several matches in rapid succession - these are essential to beating many of the timed levels)
To better your chances, you'll likely need to use the free powerups the game periodically gives you and possibly buy some extra powerups if some levels become too difficult for you.
Every day, there's a chance to get a reward. It comes in the form of a 3x3 grid of covered squares and you pick one square to uncover the reward underneath. The problem is, this feature is glitchy - plagued with server issues and failure to work when it should. When it does work, you have a chance to earn 1-3 lives, snowballs, powerups or ice picks. This should happen right after you select Single Player mode from the menu screen.
