4D Thermo Sudoku
(Eingestellt am 27. Juli 2021, 17:13 Uhr von FryTheGuy)
This is my second 4D puzzle (4D Arrow Sudoku). I am planning on making one for each major variant type, killer sudoku will be next.
This puzzle links two different sudoku grids so that if a cell is >=6 in one grid, it will also be >=6 in the other grid.
For example, if R2C4 was a 7 in the first grid, we would know R2C4 must be a 6,7,8 or 9 in the other grid. If R5C8 in the second grid was a 5, we would know R5C8 in the first grid must be a 1,2,3,4 or 5.
Basically, it is a high/low coloring puzzle where when you deduce the color in one grid, you can also color the other grid in the same location.
Normal sudoku rules apply.
Numbers on a thermometer must strictly increase as they move away from the bulb.
Cells with grey circles must contain odd numbers.
If a cell contains a number >=6 in one grid, the corresponding cell in the other grid must also contain a number >= 6.

Lösungscode: row 5 of grid 1, row 6 of grid 2

Also since the original link no longer works, here's a new solving penpa link I made (with no answer check and also some slight modifications in the rule): https://tinyurl.com/2ykdtjxl

A rather intricate opening sequence in this one that serves for a very fun parity disambiguation process later on, and the final sudoku works for both grids were certainly... pretty interesting as well x)
Thanks for this engaging puzzle!

The instructions are highly misleading. The circle-shaped circular bits of the thermometers look very much like circles to me, but they may contain even numbers.
