Thirteen basics, then eight advanced lessons. Play them in any order.
Move, rotate and flip the falling pieces to fill rows. A full row clears. Cycle the queue, or press 2 to 5, to choose which piece falls next. While a new piece pulses in the top rows, cycle or press 1 to 5 to swap it for one in the queue.
Clear more rows at once for far more: 100, 300, 700, 1,300, 2,300 and 7,100 points for one to six rows, and half as much again for each row past six.
Bonuses multiply together. Spare, the squares a row has over its width, is ×1.5 for one, then ×2, ×3 and on for two, three and more. Each glass cleared is ×1.5, and glass in a row with spare adds another ×1.5. Clears on consecutive pieces make a streak: ×2, ×3, ×4 and on. An all clear is ×2. Glass smashed or blasted scores 100 a pane. Then the speed multiplies it all, from ×1 at 1 s a row up to ×10 at speed 20. Drops score without it: 1 a row for a soft drop, 2 for a hard drop.
The speed goes up one after every five clears, whatever their size, to speed 20.
Set up your own game. A custom game keeps no high scores, and your choices stay for next time.
Or click a single key to change it, then press the new key. Backspace clears it, and Escape keeps it.
