Quickly form lines to build the Frenzy meter on the left. Filling it activates Frenzy Mode, which lets you form chain reactions that result in big-time combos; lines are worth double points. Frenzy blocks allow you to make longer cascades. Equipping power-ups before playing is the best way to score the most points. Tap the question mark next to each power-up for a description of what it does. You may equip up to three at a time. A weekly power-up is available for a limited time unless you purchase it outright or use it a set number of times to permanently add the item to your collection. Power-up blocks randomly fall into place, and you must form lines that incorporate these special tetriminos to activate them. Unused power-ups will automatically trigger when time expires.
