Flat slabs and tall towers belong to the cube family but allow different turns, including all five cuboid forms in our Magic Cube edition.
In this guide
3×3×1 · Floppy Cube
On a shape-preserving slab, turns about the broad faces differ from side flips. Side half turns change colours and rim pieces without creating an ordinary 3×3 layer. Plan: organise the broad faces, compare rim pieces, then solve the remaining rim permutation. Super Floppy models allow additional shape-changing moves and are a different variant.

3×3×2 · Domino
First solve a complete broad layer including its rim colours, then use suitable permutation sequences for the other layer. Side quarter turns do not preserve a rigid 3×3×2 shape. Do not copy a 3×3 sequence containing R where only R2 is allowed; first check that every required move is legal.

2×2×3 · Tower
On the classic Tower, the two ends and middle rim provide separate working areas. Arrange matching end pieces, align the middle pieces, then resolve remaining permutations with shape-preserving moves. The linked guide gives a specific 2×2×3 method.

2×2×4 · Four tower layers
Taller cuboids add layers. Group matching rim or middle pieces first, then preserve completed blocks. Our edition keeps cuboids shape-preserving; it does not implement a freely shape-shifting Tower mechanism. Practise short scrambles and record legal turns. Reversing a recorded scramble is a controlled study, not a general solver for an unknown scramble.

3×3×4 · A broader cuboid base
Three by three cells on each end accompany four layers. Organise centres and rim groups before fixing completed layers. Square ends can permit quarter turns; rectangular sides require half turns in the shape-preserving model. After every sequence, check the shape and completed groups.
