Tips and Tricks
Try and clear double stacks when there are multiple piles heading for the line.
Combos consist of smaller square pieces connecting with larger ones near the bottom of the board, thus removing them completely.
Take your time. You don't have to tap the first thing you see.
Use your power-ups wisely. They come in handy but they take a long time to recharge.
The -3 power-up enables you to remove three rows from the board.
