I have a couple more questions about Patchwork:

Can there be regions of different sizes?
In case IHNN's example is valid: the "number of times each value appears in a row/column", is that always the same for all rows and columns, or could different rows/columns have different amounts? E.g. a 121212 row as well as a 123231 row?

I'm changing the rules to:
Place a number into each cell so that each region contains the numbers from 1 to N with no repeats, where N is the number of cells in all regions. Numbers of the same value may not touch one another orthogonally. Each row and column contains each number from 1 to N the same number of times.

This will be there in the new IB that I'll post in a while, and in the competition areas.

I hope this answers all questions.

Edit: Feel free to ask if its still unclear.

The new IB is published.
Changes:
- Points distribution added

Sorry for the very late action but this is done now.

(to clarify for others, it wasn't an additional solution to the puzzle, it was just the correct solution sent via email.)
