This puzzle has 14 faces. And judging by the name, the Rainbow cube should have 7 colors, not 14. This means that stickers of the same color should be located on opposite faces. But the second option is also allowed, when the stickers on the cube have 14 different shades. ..and since finding the Rainbow Cube on the free market is now very difficult, the best thing you can do is buy two puzzles, and a set of stickers for the second Rainbow Cube. Which is what I did .
