4D Arrow Sudoku
(Eingestellt am 6. Juli 2021, 11:20 Uhr von FryTheGuy)
This puzzle adds a new dimension to sudoku besides row, column, and box.
The forth dimension 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.
This puzzle is loaded with a ton of mind bending cross-grid deductions that should be a lot of fun to discover.
Standard sudoku rules apply.
Numbers along an arrow must sum to the number shown in the circled cell.
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.

PS: I am also still looking for unrated puzzle recommendations to include as part of a contest. I will give away $50 to 20 randomly selected people who solve at least 15/20 puzzles.
Send me suggestions on the CTC discord (or as a comment on this puzzle).
Lösungscode: row 9 of grid 1, row 9 of grid 2

Great puzzle! I had to invent some new strategies for myself in order to manage to keep track of things, but I got there in the end! :-)

Insane puzzle! I had to keep my eyes on both grids constantly throughout the solve, and it's so amazing that the path remained so smooth and consistent at the same time :)

I am really happy you enjoyed the puzzle! I think it is one of the best puzzles I have set so far. I made a 4D killer sudoku that I will post in a few days that also turned out really well.

Incredible puzzle! Hopefully more people give it a go. I loved the concept of going back and forth between the two sudokus. The logic is excellent and a lot of fun to work out, thanks! :-)
