Step 1
Confirm you’re 18+
One number, used once, to confirm you’re 18 or older. Nothing is stored to your name.
Step 2
Meet your target
The Architect hands you one small, buildable thing — a mushroom, a mug, a little house. Simple enough to finish, odd enough to enjoy.
Step 3
Build it on the grid
Snap real 3D bricks onto the grid. Pick colors and piece sizes; build on the ground or on any face.

Step 4
Beat the clock
You start with two minutes. Tap I’m done before it hits zero. Then it gets meaner — every win shortens the next clock, all the way down to thirty seconds.
Step 5
Miss it? See the answer
Run out of time and we rebuild the target in bricks, right in the grid, so you can study exactly what it took.
