Rainbow Ball Pussel (20 holes) — large 3D sliding ball with 19 coloured balls

Rainbow Ball Puzzle 20 holes is a 3D version of a sliding puzzle: it has 20 holes and one fewer ball, so coloured balls move through the free space. The goal is to return each ball to the hole of the matching colour. This larger version is about 94 mm and about 182 g without packaging.

Who this ball is for

• For children and adults who enjoy fidget and logic toys.
• For people who want a puzzle without algorithms.

• If you want a twisty cube, this is a completely different type of puzzle.

Use feel

• The balls are pressed and moved from one hole to another.
• The larger ball is comfortable to hold with two hands.
• The solve feels more like a 15-puzzle than a Rubik’s cube.

Magnets and mechanism

• No magnets.
• There is a free space inside that allows the balls to move.
• The mechanism is sliding-ball, without layer turning.

Size, weight and materials

• Size without packaging: about 94 × 94 × 94 mm.
• Weight without packaging: about 182 g.
• Gross weight: about 184–236 g, depending on packaging.

Main advantages

• Simple rules.
• Large 20-hole format.
• Good fidget feel.
• No stickers or algorithms.

Things to keep in mind

• Not a twisty puzzle.

How to use

Move the balls through the empty space until each one reaches the hole of its colour. Do not move randomly for too long — it is easier to plan one colour at a time.
