Thanks for the compliment on my Uniqueness strategy for solving normal sudokus. I've taken a look at these minidokus but I'm confused. I understand that unlike Killer and Jigsaw variants, numbers can appear more than once in a form, but what's the significance of the dashed and solid lines?
The dashed lines are just here for better delimitation of the cells. The ones that matter are the solid ones, they delimitate forms (in which, you are right, uniqueness is not required) that need to add up to the same value for a given color. Sorry for the confusion - maybe I should remove the dashed lines entirely.
Actually, I figured it out last night but didn't have time to update my comment. The rules as I understand them: 1) Standard sudoku rules apply for rows and columns but not for blocks defined by solid line nor coloured area 2) Each solid block will add up to a value X and all blocks of the same colour will add up to the same value X. 3) The sum value may be different for each colour. 4) It's possible for a number to be repeated in a block as long as it doesn't appear more than once in any row or column
It's the fourth rule (clarification of the first) which is the hardest bit.
Rules are as follows:
1) Standard sudoku rules apply for rows and columns but not for blocks defined by solid line around a coloured area.
2) Each solid block must add up to a value X and all blocks of the same colour must add up to the same value X.
3) The sum value may be different for each colour.
4) It's possible for a number to be repeated in a block, as long as it doesn't appear more than once in any row or column.

Yeah, that's it. I'll update the home page with your description of the rules, as they are much easier to understand than my own, initial description.
Thanks, hope you'll have fun solving these !
