Trichroma Paintomino #2
(Published on 9. March 2026, 02:09 by MaizeGator)
This is the second puzzle using the novel “Trichroma Paintomino” ruleset that I invented for the Puzzle Agency Championship. If you missed the 1-star introduction, you can play here.
- Divide each bold-outlined region into three differently-sized sub-groups of cells. Then, assign one of three colors to each group so that each region contains exactly one group of each color.
- A digit in a cell indicates the size of that cell’s group.
- Sub-groups that border one another through a bold region boundary may not be the same color OR the same shape (counting rotations and reflections as the same). For example, two touching S-tetrominos in different configurations is not allowed, but an S-tetromino may touch a T-tetromino.
- When the colors of the sub-groups for each region are placed in order from largest to smallest, any pair of bordering regions must have a different order.
Solution code: The sizes of each cell’s sub-group in the bottom row, left-to-right

Very fun! I'll be sure to check out the other paintominos you've made and look forward to if you make some more! I found the wording to submit the answer a bit confusing though, took me a few tries to get it right
