Numbers3D

Turn the cube. Find the pair.

Two cells make a pair when their numbers are equal or add up to ten. Clear them, peel the cube layer by layer, and watch it fold shut as it empties. From a tiny 2×2×2 up to a towering 12×12×12.

A Numbers3D cube mid-game on a phone, with numbered cells on its outer faces.

The Daily board: one new cube every day, the same for everyone.

One rule, three dimensions

Two cells must see each other along a straight line with only empty cells in between, and you can only pick cells on the outside. Clear a whole slice and the cube folds shut and gets smaller.
