What is flipping arrows?

Flipping arrows is puzzle. The goal is to turn the dices to match the goal you choose.

The goal?

• To have all the top faces white
• To have all the top faces gray
• To have all the top faces white/gray
• To have all the top faces white/gray with the colors in the same direction (more difficult)
• To have all the top faces with the same color and the arrow in the same direction (very difficult)

How to turn the dices?

The top face of a dice have one or two colors and an arrow. You can rotate the dice by 1/4 of turn in the direction of the arrow.
Select the dice you want to "flip". The direction of the arrow, indicates the direction of the rotation. Rotate the dice by 1/4 of turn. The dices in the direction of the arrow will also rotate by 1/4 of turn in the same direction of the first dice (no matter the direction of the arrow of theses dices). If the dice is on a side and the arrow face the outside of the board, only the dice rotates.

I attached a full pdf manual with the stl files.

How many dices combinations are possible?

• On each face, an arrow can have 4 directions
• A dice have 6 faces
• There is 9 dices on the board

(4*6)^9 = 2 641 807 540 224 combinations

Some combinations are simple to solve and others much more complicated.
The complexity will also depend on the goal you have set.

How to print?

The 9 dices are printed with 2 colors. Layer 0.2mm. Infill 20%. No brim. No support. For best results, change the color at 10.2mm.

For the board and the cover use the same parameters.
