CubeQuiz is a relaxing 3D spatial-reasoning puzzle. Two sandy voxel blocks fit together when one slides down and the other slides up to form a solid box. Rotate the pieces, read their shapes, and decide which ones lock perfectly together. Progress through four puzzle packs of increasing difficulty, then test yourself in endless Challenge mode. No timers, no pressure — just you and your mental rotation skills.

Drag any block to rotate and inspect it from every angle. Each mode asks one thing:

Find the Piece — tap the block that fits the one on top.
Fit or Not — decide whether the two blocks fit, then tap Fits or Don't fit.
Find the Pair — tap the two blocks that fit each other.
Match All — pair up every block on the screen.

Clear 10 puzzles in a pack to unlock the next one. In Challenge mode, one wrong answer ends the run — how far can you go?
