How it works

One rule:not a single gap.

Each challenge sets a few pieces for you, drawn in their places. The others have to cover every remaining cell, and there is only one solution. Scroll: challenge 01 builds itself before your eyes.

Eight pieces, twenty-five cells,not one to spare.

Eight flat pieces, all different, reversible, two to four cells each. Pick a reference to examine it on its own, from every angle.

Handling

Made for the handas much as for the eye.

Shapes to recognize rather than squares to count, broad movements, success you can check without a booklet. Everything below is measured on the game's files.

Thickness

12mmOnce placed, the pieces stand 7 mm above the board: they can be picked up with the whole hand, no fine pinch needed.

Length

33 to 89mmFrom B, the smallest, to G, the largest. All are flat and reversible.

Letters

14.5mmLetter height on a hexagon (8 mm on a square), engraved top and bottom, 0.6 mm deep.

Grooves

0.4mmDepth of the tactile grooves (1 mm wide) between the cells of a piece: its shape can also be read by touch.

Eight high-contrast PETG colors on the black board; F and H in a matte finish, without glare. On-screen colors are approximate.

The challenges

120 challenges,from the first session to Wizard level.

Five levels of 24 challenges. With each level, you are given fewer pieces: two or three are left to find at Starter, five or six at Wizard. Scroll: the cursor runs through all 120 challenges.

Each column: the challenge's eight pieces. In brass, the pieces to find; above them, the given pieces. The solver explores 9 branches when it never has to backtrack, up to 21 at Wizard level. 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 or tablet, with the board's ▲ mark at the back.
  • 02Then the guide lets you search. Need help? It walks you through to the last piece.
  • 03Two more modes, no challenge needed: free play (728 ways to fill the rosette) and copy mode (take two or three pieces out of a full board, then put them back).
  • 04No account, no app. 120 challenges for ROSiX, 960 across the eight KOANiX games.
