The brief
Normal Sudoku rules apply. ANTI-KING- Cells a chess king's move apart cannot have the same number. ARROWS- Numbers on arrows sum to the number in the arrow's circle. Numbers may repeat on arrows, if other rules allow. THERMOMETERS- Numbers on thermometers increase from the bulb end. KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. MAXIMUMS- Cells shaded gray are greater than all 4 orthogonally adjacent cells.
