Glacier Blast

This achievement requires that you break three colored tiles belonging to a SINGLE opponent in one turn. This can easily be earned against three AI opponents in Feud mode. It will require some luck however as you need to match one of your breaker patterns with the pattern of a single opponents colored tiles. Look around the board and try to match up your breakers. This will likely only be possible in the first few rounds when there are ample colored tiles in play. As soon as you destroy the tiles, the achievement will pop.
