Building the tallest tower out of moving slabs challenges your reflexes and your eye in the arcade Tower Stack Challenge. Lower the sliding platform exactly above the previous tier in time, do not allow the overhanging edges to be trimmed, and collect a series of three perfect hits in a row to expand the base. Challenge yourself in the Classic version, relax in the calm Zen mode, or beat the strict timer by unlocking colorful themes and earning game points in the Tower Stack Challenge.
