Loop Limit
The brief
- Normal Sudoku rules apply.
- Draw a loop (one cell wide) of orthogonally connected cells, which does not touch itself, not even diagonally.
- Each digit on the loop indicates exactly how many times that digit appears on the loop. Eg: If there's a 5 on the loop, it means there are five 5s on the loop.
- The loop must pass through the bulb of every thermometer.
- Digits along a thermometer increase from the bulb end.
- Digits separated by a white dot are consecutive.
