Xocacap is the fixed version. MagiMaster had made the adjustment to be able to solve it. This puzzle was at first a suggestion on how to make it a little harder. It was a modified version of his decypher 2 or 3 at the time. MagiMaster has since made the other levels alot more challanging So give those a shot.

I actually prefer your dozerbased solution to LYBABUV because it just looks so orderly and clean compared to my dozerless solution. I was only restricting my solutions lately to zero dozers as an experiment. That said, here is my solution to Decryption 6 ZUNACIG: haladyp. All I can say is, what a puzzle, this ZUNACIG! First, there is reverseengineering the encryption itself. Then, there is figuring out what math to use, to reverse the encryption given the practical limitations of space. And then, there is the "coding" and "debugging" of the solution.

Knowing some details of modular arithmetic helps. For example, 3*(5*x) = x (mod 16), so to reverse a multiply by 5 you can multiply by 3 then negate it.
Anyway, I'm impressed that you pulled it off again. I guess something like this kinda implies that nearly any level that can be solved with dozers can be solved without. (Except for getting into tight spaces I guess.)

Yes, the modular arithmetic is interesting, isn't it? You can choose to negate some operations, to handle them in a smaller space. For example, to add B * x, you can instead subtract 5 * x, which is what I do to divide by 3. At the risk of a *** SPOILER *** these are my equations to reverse the encryption: e = ((d  1) * 5)  1 + ((i + 0) * 5)  (1) f = ((c + d  1) * 5)  1 + ((j + i) * 5)  e g = ((b + c  1) * 5)  1 + ((k + j + i) * 5)  f h = ((a + b  1) * 5)  1 + ((l + k + j + i) * 5)  g It's not exactly the reverse if you write out the encryption and solve for eh  I adjusted it to make easytoimplement patterns. At the risk of a bigger spoiler, I won't describe more here unless anybody is interested. This took the puzzle to another level  *quite* an interesting challenge, it was. Edit: I only now see that what I just wrote about 5 * x and divide by 3, is exactly what you wrote in the post above.

Yeah. I wrote it all out and solved it too, but I didn't really think of trying to make the equations easier to implement. I might make another decryption puzzle later, but for now here's a new Matching Problem: XYMOGAH

And here is a solution for XYMOGAH: Knitting Loom for Xymogah pusabid.

Those are both very cool solutions. Here's another Matching Problem, although, I'm not sure there's enough room to solve it. MYMOBOK

Those matching and decryption puzzles are really cool and the solutions are amazing. I haven't even tried to solve them, would take me too long. I did solve Tiny 9 though: gukevup.

MagiMaster

Unfortunately, I haven't managed to solve the newest matching problem yet (so I'm still not sure it's solvable.)

matching problem 1  tecycyr: myhabyb (I checked this several times replacing the ? with an F and it worked every time, but it still looks like dumb luck to me) matching problem 2  xymogah: mixuteb (you can probably tell that I looked at the other solutions to #1 before moving on to #2)
