Tetris Boo

Drag left or right anywhere on the screen to slide the falling block. It follows your finger.
Tap to rotate it. Drag down slowly to soft drop, or flick down to drop it all the way.
Flick up, or tap the Hold box, to swap the block for one saved for later.
Fill a row with no gaps to clear it. Clear four rows at once for a Tetris.

📱 Drag to move, tap to rotate, flick down to drop⌨️ ← → ↑ ↓ Space C

🎯 Objective

Stack the falling blocks into complete rows. Rows disappear when full. The run ends when the stack reaches the top.

📊 How you score

Clearing rows scores 100, 300, 500 or 800 points for one to four rows, times your level. Back-to-back Tetrises and T-spins pay 1.5x, and clearing rows on consecutive drops builds a combo bonus. Soft drops score 1 point per row and hard drops 2. You level up every 10 rows and the blocks fall faster.

💡 Tips

Keep the stack flat and leave one column open for a long block. A Tetris is worth eight times a single.
The faint outline shows where the block will land. Check it before you flick.
Hold a long block for the moment you have a deep gap, not just to escape a bad piece.
A block rests a half second before it locks, so you can still slide or turn it once it lands.

How do I control Tetris Boo on a phone?

Drag left or right to move the falling block, tap to rotate it, drag down slowly to soft drop and flick down to drop it instantly. Flick up to hold a block. On a keyboard use the arrow keys, Space to drop and C to hold.

How does scoring work?

Clearing 1, 2, 3 or 4 rows scores 100, 300, 500 or 800 points times your level. Back-to-back Tetrises and T-spins earn a 1.5x bonus, consecutive clears add a combo bonus, and every dropped row adds a point or two.

What is a Tetris?

A Tetris is clearing four rows with one block, which needs a long straight block dropped into a tall, empty column. It is the biggest line clear in the game.

Is every run the same for everyone?

Yes, for daily and challenge runs. The order of the blocks comes from a shared seed, so you and a friend get the exact same pieces and the better stacker wins.
