Trichroma Paintomino #4
(Published on 20. March 2026, 02:35 by MaizeGator)
I’m happy to present the fourth puzzle in the Trichroma Paintomino series! If you’re late to the party, you can catch up by clicking these links: #1, #2, and #3.
- 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 column 7 (the right-most FULL column), top to bottom

I gotta say, I rushed through the first three and the concept really got me thinking about possibilities for the next few days. I was really hoping a new one would come soon!

Love these puzzles, but a good quality of life feature would be to give a cage total saying the total size of a region. Counting them up each time is a pain.
