Read from the board image on this page, last measured 2026-10-21. These measurements describe the visible pieces; they do not claim clamp ownership or a solve order. Each ring's clamp is owned by a neighbouring ring, and a held ring comes free as soon as its gap reaches that clamp. Start with the outer rings that hold nobody, then work inward layer by layer.
How to read the Level 21 board
Start with the pieces that hold nothing
A piece that does not hold another piece can move without disturbing a connector someone else still needs. Clear those outer pieces first, then work inward one connection at a time.
1 ring-shaped piece on this board
Measured from the board image on this page, the play area contains 1 ring-shaped piece. Every one has a measured opening, so every ring can be turned; the opening is the only part that passes a clamp or sleeve.
The board uses 7 colours
The measured palette runs to 7 colours: purple, light green, light blue, dark green, orange, red and blue. When two pieces look alike, use their position and the connector they touch to tell them apart.
A crowded board — turn in small steps
Pieces cover 33.1% of the play area. On a board this dense, stop as soon as the opening reaches the connector; a long spin is easy to overshoot.
