or solve online (using our beta test of Penpa-Edit tools)
This is a “Twisted Tuesday” puzzle variation.
Theme: TomTomTom: The Next Dimension?
Rules: Variation of TomTom rules, using digits from 1-8. In this variation, similar to Isodoku, the rows bend along the surface of an apparent cube.
Answer String: Enter the marked “column” A, starting at the arrow, followed by a comma, followed by the marked “column” B.
Time Standards (highlight to view): Grandmaster = 2:45, Master = 5:00, Expert = 10:00

Not as hard as I was afraid it might be. I did enjoy just how much unmarked territory filled itself in at the end (since nearly half the squares aren’t part of a calculation). Also, the usual iso-sudoku rule of two of everything per face definitely came in handy.
I did not know about the two of everything per face rule but can see it must be true. I guess if I knew this rule before this puzzle (and other iso-sudokus) would be a bit easier to solve.
How to do this one in grandmaster time? I’m wondering how some people look to solve this one in that target time… I’m really hope u can describe part by part or cell by cell that should I tackle to solve this one..
Look at the 49 block.It can be filled in only one way and look at the 21 block to the left of that.It can be filled in only one way too after you fill the 49.The rest will fall fast.
thanks…but u also dont qualify for grandmaster time.. y? where do u wasting time most after knowing the starting?
I did not start the way that i mentioned 🙂 .It was only after solving that i saw it could be solved that way.
u should try to do better time than that since u can understand the logic..unless u r not really interested in solving quickly?
It’s much easier to point out the chain of logic after the fact, then to find it in the first place. I mean, if I can spot the 21 quickly, I would probably have gotten grandmaster time myself.
u hav a good point over there..

good puzzle
Loved how the clues work together (the two twelves for instance).
Towards the end it felt more like a sudoku chasing singles.
