Dot dot dot
Rules:
1. Irregular: All regions must contain digits 1-9, once each.
2. Renban: Lines in the grid are renban lines, which must contain a set of consecutive digits in any order. Lines may branch and cross one another. To avoid confusion, crossing lines are drawn in different colours.
3. Mod3 dots: Cells separated by a green dot must have the same remainder when divided by 3 (=mod3 value). For example, a 1 could be connected to either 4 or 7 by a green dot. A 5 could be connected to either a 2 or 8 by a green dot. Simply put: Digits connected by a green dot have a difference of either 3 or 6. Negative constraint: All possible green dots are given.
4. Kropki without negative constraint: Cells separated by a white dot are consecutive. All possible dots are not given.
5. Standard thermometer: Digits along a thermometer must increase from the bulb end.
