True 3D pit
Look straight down a green wireframe pit. Settled cubes take the colour of their layer, so depth is readable at a glance.

Why this version
Classic Blockout, with a few helping hands
The pit, the pieces and the controls you remember, plus visual aids that make learning 3D stacking easier.
Ground contact highlight
The part of the falling piece closest to the floor glows amber, so you always know which cubes touch down first.
Hole warning
On levels 0, 1 and 2 a blinking icon warns you when the piece would leave a gap below it. Rotate or move until it disappears.
Three classic setups
Flat Fun, 3D Mania and Out of Control — or any pit from 3×3×6 to 7×7×18 with Flat, Basic or Extended pieces.
Your keys, your layout
Rebind every rotation key, or switch between QWERTY and AZERTY presets in one click. Settings stay in your browser.
Desktop and mobile
Scales from phones to 27" monitors, with on-screen touch controls and fullscreen mode.

Scoring
Every locked piece scores its cubes plus the layers it was dropped, multiplied by the level. Clearing several layers at once is worth far more, and emptying the pit earns a big bonus. Every 3 cleared layers the level goes up and pieces fall 36% faster (from 5.5 s per layer at level 0).
FAQ
Questions
Are my scores saved?
No. There is no server. The high score lives only while the page is open.
What does the hole warning check?
It simulates the drop and looks under the lowest cube of every column of the piece. If any of those cells would stay empty, the icon blinks.
Can I play on my phone?
Yes. Use the on-screen pad to move and drop, and the X/Y/Z buttons to rotate.
