Another puzzle to commemorate the 2022 World Snooker Championship. This puzzle might look a little gimmicky but it actually has some fun and tricky logic. (3 stars difficulty overall but a few harder steps along the way.)
Regular rules:
- Normal sudoku rules.
- Kropki: Cells joined by a black dot have a ratio of 2:1.
- Thermo: Digits along the snooker cue increase from the butt end (dark brown.)
- Even/odd cells: The blue piece of chalk is an even digit. The cue ball in box 2 is an odd digit.
Special rules:
- Perimeter sum: The perimeter cells of the grid sum to 147 (a snooker "Maximum.")
- Cages: The cages, read as two 2-digit numbers, sum to 147.
- Red/Colour: Each of the boxes 2-7 must contain a horizontal domino containing 1N, where N is the box number. For example, box 2 has a 12 domino, box 3 has a 13 domino, etc. The 1 always comes first, and each such domino is fully contained within its own box.

Clever 147 Easter egg at the end.
// Ha yeah. At a point in the construction I was looking for a way to disambiguate an extended pattern. I realised I could put 147 down there, so I thought I'd instruct the solver to find a vertical 147. But in the end it seemed too arbitrary and convoluted a rule, and I discovered that simply by including the given 4 I could achieve the goal.

This wasn't an easy one, but it was fun to play pool!
