Invisible Thermometers: A Game-Changing Sudoku

** TODAY'S PUZZLE **
So many of you have requested that we attempt this puzzle, Invisible Thermometers by Nahileon. The ruleset seems completely ludicrous - who would come up with such a thing?! Well it turns out that, yet again, Nahileon has produced something utterly mind-blowing. But it is quite hard ;)

Play the puzzle at the link below:

https://app.crackingthecryptic.com/su...

Rules:
Place the digits 1-8 once each in every row, column and region. A digit in a cell with a circle must be odd. A digit in a cell with a square must be even. There are invisible thermometers in this grid. Every empty cell (the 6x6 in the center) gets visited by one of those thermometers. Digits on a thermometer increase from the bulb on one end to the tip on the other end. The thermometers are orthogonally connected and don't fork or overlap. A thermometer may have length 1 if it's bulb and tip are the same cell. The difference between bulb and tip must be unique for each thermometer.

** NEW SUDOKU HUNT INCOMING TOMORROW **
A new sudoku hunt, The Planets Suite, will be released tomorrow at 4pm UK time on Patreon. It's one of our own and should be slightly easier this month. Well done to all of you who solved DiMono's Jewels Of Osiris hunt this month - watch today's introduction for details on the best entries (and the outro for the roll call of all successful solvers.)

Join us on Patreon for as little as $2 a month to play.
