Daily 3D Puzzle Archive
Missed a day? Every daily 3D puzzle and spatial test is here. Easy early in the week, expert on Sunday.
Each day has two parts. First, a build puzzle: you get the top, front and left side views of a stack of cubes and build a solid that matches all three. Then a 5-question spatial reasoning test on the same skill: pick the right view, pick the right solid, draw the missing view and find the mistake in a set of views. Today's puzzle is always at the 3D puzzle game.

How the week gets harder
- Monday and Tuesday, easy: a 3×3 base, stacks up to 2 high, 4 to 9 cubes.
- Wednesday and Thursday, medium: a 3×3 base, stacks up to 3 high, 6 to 14 cubes.
- Friday and Saturday, hard: a 4×4 base, stacks up to 3 high, 9 to 22 cubes.
- Sunday, expert: a 4×4 base, stacks up to 4 high, 12 to 30 cubes.
Bigger, taller stacks hide more cubes behind others, so on harder days check all three views before you decide. Everyone gets the same puzzle on the same day, and a new one appears at midnight US Eastern.
