Puzzle By Number Rainbow is a 500-piece mosaic set for builders who want a bigger color-matching challenge and a striking finished display.
Every band of the rainbow is built through numbered placement, teaching sequencing, contrast, and patience across a larger canvas than 250-piece puzzles.
It is a favorite for classrooms, pride displays, and kids who love bright geometric art with clear step-by-step instructions.
At 500 pieces, the project feels substantial while still finishing faster than the 800- and 1400-piece flagship puzzles.
When the rainbow is complete, reuse the vivid palette for clouds, unicorns, flags, and abstract Plus-Plus art experiments.
Suggested for ages 5+
