Thanks for the feature, BremSter. I hope I was able to give you an enjoyable distraction for a while.

@aamocryp 3 месяца назад

this was one mean puzzle, although I was so happy once I finally figured out the 10-clue and yet it all had a wonderful flow

@victorfinberg8595 3 месяца назад

i broke it on my first attempt. on my second attempt, i figured out what i did wrong, but my solution was suspect. third times a charm. those diagonal sandwiches are VERY tricky. 11119 is a THREE sandwich. 99991 is a twenty-seven sandwich.

@donaldsnyder1543 3 месяца назад

Couldn't quite understand this one , the diagonal wrecked my head. I'll just watch Brem lol😊.

@francescopetracca374 3 месяца назад

Yeah, that 5 and 10 clues are mind-blowing! A really great puzzle, props to EPH!

@Vernicho 3 месяца назад

the long 10 clue was key for me to solve the clues, still some nice sudoku to finish off as well, a very interesting twist on the normal sandwich variant. Thanks to Bremster for featuring this excellent puzzle from EPH.

@kana2112 3 месяца назад

That started off well, but that 10 clue totally got me.

@JohnRandomness105 3 месяца назад

Ditto. I found myself with only one cell to put 19 in block 9.

@annek3296 3 месяца назад

I thought for the longest time that I had broken the puzzle, but gamely kept on putting in values, until I realized that the "5" sandwich could "legally" be part of the "10" sandwhich. I'm simultaneouly impressed by & angry at the setter!

@victorfinberg8595 3 месяца назад

7:18 having made the same mistake myself a couple of times, i was watching your solve. NO, you have NOT made that mistake. by luck or skill, you always remained within one REGION, and so could not have duplicate crusts.

@bobfish7699 3 месяца назад

that 10 clue really caught me out..

@praematura 3 месяца назад

I so totally horked this on the first attempt before realizing what I was doing wrong. Came back to it a few hours later, and this time made it through in 11:00 (conflict checker off), but lets add 3-4 minutes for what little bits I remembered from the first attempt. What an amazing puzzle from EPH, many thanks to them for it and for BremSter for presenting it!

@57thorns 3 месяца назад

This one is really tricky.... ugh. I thought about the pitfall and I will still have to restart. Final time fifteen minutes, not too shabby for me.

@57thorns 3 месяца назад

Also, let's be very clear that I do not cut sandwiches with a table saw... :-)

@boydegg 3 месяца назад

Ok this twisted my brain for hours. It seemed impossible to solve ... that long 10 clue is what tripped me up. I never thought of a sandwich clue as having 1s within it. D'oh! It works on a diagonal.

@StGordo61 3 месяца назад

It was from the Peanuts cartoon that cutting a peanut butter sandwich, instead of folding it, halved its flavour! I’m with you BremSter…never cut! Thanks for posting whilst you’ve got other stuff going on…. Really appreciate all you do, so all the best! And thanks for the puzzle too @TheEricthefruitbat!

@sotek2784 3 месяца назад

This is a very cool puzzle, but that was a sneaky use of the implications of the variant! (but? *because*, hah)

@billbliss7407 3 месяца назад

This completely broke my brain! It took BremSter less than 15 minutes to get to the place it took me an hour to get to -- and I was completely stuck. What a cool puzzle.

@aamocryp 3 месяца назад

really struggled with this one, had to restart my progress at least three times thinking I'd broken the puzzle at some point until I understood the rules

@Li3Kung4 3 месяца назад

After your reminder in the 8th minute I finally got it by coloring the 1 & 9 differently.

@anaayoung9142 3 месяца назад

Fun puzzle. I like the way the rules worked here. Thanks! 😊

@林老師-i5d 3 месяца назад

17:41 for me nice puzzle

@megaminxpll 3 месяца назад

Fun and easy, done in 9:58. The 10 diagonal clue was quite obvious how to solve it.

@JohnRandomness105 3 месяца назад

I finished it, although it took me a while. I wonder if BremSter falls into the same diagonal sandwich trap that I fell into. Now, on to the video. 7:20 Sounds as if he spotted the trap. Very good. 11:30 That's what it will be. Repeated 1s before the 9. That 10-clue got me, although thank goodness, I didn't have to backtrack to fix it. (I was only centermarking 19s, not placing digits.)
