About this game

Turn and slot falling blocks to clear full rows

What this game is

Four-square blocks drop from the top one at a time. Turn and slide them into place, and any row you fill completely disappears.

The seven shapes come out of a shuffled bag, so the piece you are waiting for never stays away for long. Every 10 rows you clear, the level rises and blocks fall faster.

How to play

Buttons or gestures
Use the buttons to move, turn and drop, or work the board directly: slide sideways to move, tap to turn, flick down to drop.
Clear several rows at once
One row is 100, two are 300, three are 500 and four are 800, all multiplied by the level. Leaving a one-wide gap for the long bar pays off big.
Watch the shadow
A faint shadow shows where the block will land. Line up the shadow before you drop and mistakes drop too.

Frequently asked questions

How is the score worked out?
Rows cleared give 100, 300, 500 or 800 times the level. Soft drops add 1 point per row fallen and hard drops add 2.
What if I switch apps?
The game pauses while the page is hidden and picks up where you left off.
How do I play on a computer?
Arrow keys move, the up arrow turns and the space bar drops.
