Spa Day, by James Sinclair

Normal sudoku rules apply, and all clues are standard.
Arrows: the sum of the digits along an arrow is equal to the digit in the connected circle, and these digits can repeat if allowed by other rules.
Thermometers: digits on the thermometer increase from the bulb.
Digits in cells with a shaded circle are odd.
Note: this rule does not apply to the thermometer bulb (r8c8), which may contain a digit of either parity.

those quiet little dots are so powerful, and critical, in working out the 89 pair in the early middle game.
