Tile and holder in numbers
All dimensions come straight from the 3D print files of the current set. Use them to check what fits where, build your own holder or design special tiles.

- Size25 × 25 mm
- Thickness3 mm
- Corner radiusapprox. 3.2 mm
- Digit height10.1–10.6 mm

Jokers and special tiles share the same body. Instead of a number, the joker shows four triangles (11.7 × 6.7 mm each) in two colours. Special tiles carry a symbol of up to 15 × 15.5 mm, inlaid 0.6 to 0.75 mm deep.
The tile holder
One holder takes 28 tiles: four rows of seven. Each step has a 25.5 mm back rest and a 5 mm deep ledge. The tiles lean back by 20°, so every row stays readable from the front.

- Tile angle20°
- Legs2 × 48.9 mm, 10 mm thick
Printed in Bremen
Every part comes off a 3D printer. The tiles are printed face down, with the digits as a second colour in the same print. Small marks are part of it and make every set unique.
