How to play
Drop the seven shapes into the ten-by-twenty well. Complete a horizontal row and it shatters, everything above falls one row, and you score. Clear four rows at once — a tetris — and the shatter is worth eight times a single line.
Speed
Every ten lines the pieces fall one level faster. The pieces never change shape, only the time you have to place them.
Good to know
Best score is stored in this browser. P pauses; the well is saved if you close the tab mid-game? No — a reload deals a fresh well.
