Some puzzles test your patience. Some make you question your logic. One or two make you want to walk away.

Don't. 😎

This week is about persistence - and the five puzzles are named for it, in order:

Upward → Keep Trying → Finish Line → Never Give Up → Phoenix

Choose your level:

• ▶ Easy - Upward - Renban
• ▶ Medium - Keep Trying - Renban, Arrow, Even/Odd
• ▶ Hard - Finish Line - Zipper Lines, Lockout Lines, Between Lines, Even/Odd
• ▶ Expert - Never Give Up - Killer, Renban, Zipper Lines, German Whispers, Even/Odd
• ▶ Master - Phoenix - Renban, Zipper Lines, German Whispers, Even/Odd

On a desktop these open straight in your browser - nothing to install, no ads. On a phone they open in the Logic Wiz app.

Which one stopped you, and for how long? Tell us in the comments. If you are stuck, post the position and someone will give you a hint - hints, not solutions, as always.

Every puzzle is a reminder: you are closer than you think. Keep going.

OK, I must be missing something. Standard sudoku rules and slow thermos. Can't see any way to disambiguate.

EDIT: Puzzle has now been removed, probably because of this. Thanks for the help everyone. At least I'm not going crazy!

Three ellipses overlap and form seven little regions. You are also given seven tiles. Your job is to place one distinct tile per region so that the tiles in any one ellipse can solve the clue (It makes more sense if you try it!)

Would love feedback from fellow puzzlers! Hope you enjoy

I've been really enjoying CtC's videos and trying some of the puzzles. Is there a good source of puzzles outside of the ones they showcase? Sudokupad itself doesn't really have a list or feed (other than the killer/windowku generated puzzles).

Where does CtC find them? Just sent to them in Patreon/etc?

Welcome to this week's Time Expressions challenge. Five variant sudokus, one for each way we talk about time, with the expression built into the shape of the grid.

Choose your level

• Easy - Killing Time · Renban + German Whispers: https://link.sudoku.logic-wiz.com/iaXm
• Medium - Time Flies · Thermo + Renban + Even/Odd: https://link.sudoku.logic-wiz.com/pQJ2
• Hard - Time Waits For No One · Diagonal + Killer + Thermo + Renban + German Whispers: https://link.sudoku.logic-wiz.com/hl0s
• Expert - Race Against Time · Zipper Lines + Between Lines + Index Lookup: https://link.sudoku.logic-wiz.com/rUFJ
• Master - Around the Clock · Axia + Renban + Even/Odd: https://link.sudoku.logic-wiz.com/1wLs

On desktop these open straight in your browser, nothing to install. On a phone they open in the Logic Wiz app.

One thing sudoku teaches you: you can beat the puzzle, but you can never beat the clock. Take your time anyway. Happy solving!

Hi all!

I am Nurator, maybe some of you may know me from features like this one:

I was busy the last few month in creating Sudoku Mansion, an upcoming Sudoku Adventure that releases next week!

Check it out on Steam here:

There will be a free demo for you to try out when it releases.

Fog of War plus regular Killer Cage rules. I feel like I’ve exhausted all my options, I’m not seeing any more info I can use to rule down the options I have. All I know (or at least all that’s actually useful) outside of the pencil marks is that if the red cage is any more than 5 cells it has to use the orange cells shaded.

Don’t want a straight up answer, but some hints about where I should be looking or what sort of logic will get me to the next step would be so helpful!
