| Hey Mito!
I just solved it. The license check is rather simple but the obfuscation is quite hard to defeat, so I was able to solve it using a debugger. I'm not satisfied with my solution and would like to develop some tooling for it( tried but failed :( ). It'll be great if we can chat about it. How can I contact you? |

| Solved it :)
Learnt a lot and in love with Java now haha...
Also I found that multiple solutions are possible
Awesome crackme!
Keep 'em coming

| Amazing crackme!!
Solved Game1
Used z3 for generating the encrypted string
Looks like it needs more time for the other 2 .. Will try this next week :) |
==> |
| Solved it !! Tho its a level 1 for sure |
==> |
| Looking forward to your next android crackme! |
==> |
| hmm You can just copy paste the text I guess.. If thats what u want. Also a graph looks better to work with imo :) |

| Hmm.. I doubt! @x0r19x91 can't u write a virus? lmao |

| Nice anti-debugging tricks!!
Took me a while to defeat em
Also is there a way I can contact you @EXTORY ?
BTW Thanks, Will try to make a writeup :) |
==> |
| Tricks ;) |
==> |
| Funny trolls along the way.. BTW It is nowhere near Level2 |

| This crackme was nice and informative but I don't see any kind of replacements for numbers. Also I don't know what am I missing but it doesn't accept a serial for some cases like "abcdefgh". |
==> |
| I m glad u liked it guys :) |

| Hey @rootabeta, What I wanted to say was that it doesn't really need a keygen, also you'll find many crackmes which would lead you to the solution right away, so you just have to look for spoilers (don't read my comment).
PS @juansacoo thanks for posting another one :XD |
==> |
| Serial depends only on the last character of the name, Nice! |
==> |
| Too easy! (input % 0x4c7 == 0) |
==> |
| An easy one, solved it using Ghidra :) TBH it should be a level 1 crackme tho. Thanks for it D4RKFLOW |

| Hey I'm facing the same problem as specified by @fotel, I got the same key. I'm looking for a solution without debugging it!! |
==> |
| @mikejerez you can submit it in the solutions section.
Read FAQ before submitting it though.. |
