QiYi 123 Cuboid — simple 1×2×3 cuboid for a first step into non-standard cubes

QiYi 123 Cuboid is a compact 1×2×3 puzzle, logically very easy and perfect as an introduction to cuboids.
It always keeps its rectangular shape, so it doesn’t turn into crazy forms like shape-shifting mods.

Who is it for

• kids from about 5–6 years old as a first “unusual” twisty puzzle;
• teens and adults who want a very light, fidget-friendly cuboid;
• collectors who build a full QiYi 123 / 133 / 223 / 233 cuboid line.

In terms of difficulty it’s clearly easier than a 2×2, let alone a 3×3 — more of a logic / coordination toy than a hardcore challenge.

Turning feel & play

• smooth and light turning with no heavy catches;
• compact size fits nicely into small hands;
• quickly becomes a “fidget puzzle” you just keep twisting without thinking.

Unlike more complex cuboids (133, 223, 233), QiYi 123 Cuboid looks quite calm even when scrambled, and can usually be solved intuitively, without algorithms.

Size, colours, materials

• form factor: 1×2×3;
• roughly one edge is similar to a standard 3×3, but the cuboid is more elongated;
• bright stickerless plastic (coloured plastic, no stickers);
• durable ABS plastic with rounded edges, comfortable for children.

In short

QiYi 123 Cuboid is a “starter cuboid”: compact, simple and pleasant to turn. It pairs nicely with the 133 and 223 cuboids if you want to show how the difficulty grows as the shape becomes more complex.
