How it works

One rule:thin on thick.

Each square of the frame takes two cells, one below, one above. One must be thin, the other thick; otherwise, it sticks out. Scroll: challenge 01 builds itself before your eyes.

The box · 20 squares, 2 levels

  1. IThe frame5 × 4, two levelsTwenty squares, 15 mm pitch. Each takes two cells: one below, one above.
  2. IIThe given piecesB, I, D, A, then F, GChallenge 01 sets six: four on the bottom level, flat face down, then two on top, flipped over.
  3. IIIThe stepsThin on thickA cell is 4 or 8 mm tall. In each square, one is thin, the other thick: 12 mm, not one more.
  4. IVThe pieces to findH, J, E, CH completes the bottom level. J rests on H, D and I: six cells that must fit all at once.
  5. VThe lid is the judgeFlat or notTwo thick cells in the same square, and a piece sticks up by 4 mm: the lid won't go down.

Ten pieces, forty cells,two heights.

Ten flat pieces of 3 to 6 cells, one flat face, one stepped face. Eight alternate thin and thick in a checkerboard; A and C are the only ones that break the pattern. Pick a reference to examine it on its own, from every angle.

Challenge 66 · Expert · no pieces placed

Each thumbnail: top level above, bottom level below. Bright = thick cell, dark = thin. The two levels are always the negative of each other.

The challenges

120 challenges,from a minute to an evening.

Five levels of 24 challenges. The higher the level, the fewer pieces you are given: six at Starter, just one at Wizard. Scroll: the cursor runs through all 120 challenges, from the simplest to the most devious.

Bar height: size of the solver's search tree, in nodes, on a log scale. Every challenge has a unique solution, verified by two independently written solvers.

The guide

No booklet.The QR code on the box opens the challenge in 3D.

  • 01The given pieces go in one by one, in 3D, on your phone: the bottom level first, then the top. Every piece carries its letter, top and bottom.
  • 02The relief is drawn exactly as it is, thin cells and thick, so the piece on screen is the one in your hand.
  • 03No account, no app. The guide works offline once loaded.
