    A lot of the latest solves on the channel have been incredibly, incredibly difficult ones, and the videos were over 1 hour long as a result. However, even though this one has no given digits to start (not even in the killer cages), it's actually quite approachable, and the video much shorter as a result... so I figured I would post it.

    p.s. As always with cracking the cryptic videos, you can give the puzzle a try yourself using their webapp:

    I always enjoy cracking the cryptic, but the puzzles are usually far beyond me to actually complete - so I'm always happy to hear about an approachable one. I took a crack at it, but needed to go back to the video a couple of times for a hint - and then I had a faulty assumption which luckily was only pencil marks and never made it to incorrect digits, but still took me a long time to figure it out. Listing out all of the possible cage variations for a given cage size was very helpful (but also lead to my faulty assumption). Spent way too long on it, but I did solve it.

    Side note - are the cracking the cryptic phone apps worth it? They are $5 - which triggers both my "this is expensive for a phone app" and "this is the price of a good cup of coffee" senses...though given that each app is $5, I'd only be inclined to get one of them. Does anyone have any experience with them and have a favorite?

      I’ve bought almost all of their apps and would say it’s 100% worth it. Their interface is great and the amount of puzzles you get will keep you busy for a long long time. I don't exactly know how frequently they update them but you do get new puzzles every now and then.

      For reference, I bought them almost exactly a year ago and their Classic Sudoku app has 100 puzzles right now and I've finished about 50 of them. Their Chess Sudoku has 85 puzzles spread over 3 different variants and I've completed about 80. Their Thermo Sudoku has 80 puzzles and I've completed 60 (I just opened it and it told me 20 more got added lol). I think you get the idea. :P

        I'll echo this response. The puzzles are excellent, and very well put together. Each has been hand-designed and checked to ensure that there is a unique solution, and a proper logical path to follow (as opposed to a lot of sudoku apps which just create a grid via algorithms).
        My personal favourite is the thermo app, but that's because I prefer the logic of thermos to others. I have the sandwich one as well, but I struggle with the maths aspect of the sandwich puzzles (how many ways are there to make x with y digits?). They're all very well made, so I'd suggest getting whichever style of puzzle speaks to you the most
