BLOCKO
The classic falling-blocks puzzle, built from glossy 3D blocks.
Seven block shapes fall into the well one by one. Move and rotate each piece so it lands in the right place – when a row is filled from wall to wall it clears and everything above drops down. Clear four rows at once for a QUAD, the biggest bonus in the game.
BLOCKO adds modern comforts to the timeless puzzle: a ghost piece that shows where the block will land, a hold slot to save a piece for later, a preview of the next three pieces, and fair rotation that slides a piece off the wall when it fits. Every ten rows the level goes up and the blocks fall faster. Free in your browser, on computer or phone.

The seven blocks
- I (light blue) – the long bar – the only piece that clears four rows at once. Keep one column open for it.
- O (yellow) – the square. It never rotates, so drop it on any flat spot.
- T (purple) – fits almost anywhere and can twist into tight gaps for a T-spin bonus.
- S and Z (green and red) – the zigzags. Lay them flat on matching steps so they leave no holes.
- J and L (blue and orange) – the hooks. Great for filling corners and the edges of the well.
From level 1 to the top
Levels 1–3: warm-up
Blocks fall slowly – one row per second. Learn the controls, keep the stack flat and leave the right-hand column open.
Clearing four rows: QUAD
Fill four rows except one column, then drop a straight I piece into the gap. A QUAD scores 800 × level, and another QUAD right after it scores 50% more.
Levels 4–9: speeding up
The drop speed rises with every level. Use the ghost piece to aim and hard-drop to save time; hold an I piece for the next QUAD.
Levels 10 and up: fast drop
Pieces fall in a flash. Plan with the next queue, avoid tall towers and clear rows early – combos of back-to-back clears add bonus points.
Game over and high score
The game ends when a new piece has no room to appear. Your best score is saved in your browser – start again and beat it.
Tips and tricks
- Keep the stack low and flat – bumps and holes are what end games.
- Leave one column at the side empty for the I piece and clear four rows together.
- Use hold for a piece that doesn't fit now (often the I or a zigzag).
- Watch the next pieces, not only the falling one.
- Hard drop (Space) as soon as the ghost piece is in the right place – it saves time and scores 2 points per row.

1 row = 100, 2 rows = 300, 3 rows = 500 and 4 rows (QUAD) = 800 points, multiplied by the level. Soft drop gives 1 point per row, hard drop 2, and combos of clears in a row add bonus points.
