Decrypto

Game is fun, I really enjoy encryption and decryption themed games. However I'm stuck on level 16. You're supposed to multiply two matrices by each other, however the matrices are all 2x1 meaning they can't be multiplied, not only that but there are no inverses for 2x1 matrices. If I've misunderstood the point of the level then the hints and the given information need to be clearer.

Ads between every level is a bit much. I enjoy the aesthetic and color scheme, but maybe ads between every other level instead?? For people who finish these quickly, most of our time is spent sitting through ads. It gets old fast, and while I enjoy your game, currently my time is being spent 1:4 on actually completing the levels and just watching Ads. At least get interactive or shorter Ads?

The game is good but ads after EVERY puzzle make this a deal breaker. (And no, I'm not going to pay to remove.) Edit: I'm glad developers take time to read a comment! I would hate to give a bad review to a game where somebody couldn't stop to read the words I wrote! Degraded to 1 star.

The game in and of itself is great. It has great linear movement in terms of flow from one cipher to next. However the game's design is very cramped almost to the point of claustrophobia. Moving the home and help buttons so that they don't block parts of the cipher would help immensely. That and the fact it penalizes you for inputting an answer before you have actually finished. So maybe adding a submit button to one of the sides. Other than that the game is great.

What the hell even is this? I may not be one for decryptions, but this was awful. I didn't understand the second level. Tried using a hint. The hint did nothing expect waste a hint... twice. Uninstalling.

I got stuck on level 14 I believe, might be 13 but not sure. I unlocked all the hints and it says 'pictures indicate decryption' it also says 'NP = CL' but I'm not sure how this relates to the decrypton. The arrows are confusing me as I can't seem to get any of the right letters. Also I'm not sure if it's just a coincidence that the NP = CL thing works similar to the four square one. Anyway I would appreciate any clues or help. Thanks

I love this game but I am stuck on the ZODIACS problem. I've tried looking it up online and used decoders but they're all saying that it's playfair (Which is what it looks like) but none of the decoders can solve it. I've tried brute forcing it myself but nothing is working ;-; Edit: for clairfication it's the problem in one of the example screenshots. The numbers it has are 35|67|72|59|99|66|67|

The game was fun for the first few levels, until you have to look up more information on how to solve the level. I got stuck on a level, but haven't been able to get past it. I've gone to the web to try to find something, but there was nothing. The hints weren't helpful either. I would get all the hints, and they would give me new information, but I didn't know what to do with it.

It is really good, it is hard and you need to have some prior knowledge to play though! I also am having lots of problems with the BIBLE one I know where to look but can't find the word.

I got through the first 2 levels easily but the third one said it was a 5 shift Caesar cipher and I did it but keep getting this: Celcdsdesyx. I have no clue what to do.

Honestly, you should have all these levels laid out like one of those grids that unlocks gradually, ability to go back and solve a past one also maybe. Maybe also a score system based on a timer for solving. The puzzles are good but there's nothing else, really. Good job making the hints witty.

It's so fun. But I stuck at level 12, 4 squares cipher. I try to decrypt it on every way, but all I get is BIBLEA or some random letter.

It's a good game. I enjoy solving the problems. It might be a little difficult. It's also a bit ad filled, but so is everything now so I don't blame you for it.

It's a great game! But i'm stuck on level 10...i keep getting ksshporanum?? Help me out please!!

Fun but really hard would like an additional app with hints and answers maybe cause I'm so stuck on this level I think 13 with job, hints lead to the Bible but I've slotted in all the words o could think of from that passage. Frustrating but satisfaction once you get there

I'm stuck on #7 qbgj. I have no idea I tried looking at the top letters but there no B and the letters I get are nonsense help please

Great concept, excellently executed. The games really encourages players to look up infos on internet, makes the players think and concentrate on the tasks. Instead of some "out-of-the-box" thinking, this games requires you to know the know-how of the cypher used. The ads are okay, the amount is just right. I especially enjoy the more recent cypher like Matrix, which got me whipping out my calculator to solve it. Great work man, looking forward to the new updates.

This game was terribly easy, I spent more time stuck in ads than I did actually solving puzzles. The puzzle I liked the most was the Occam's Razor puzzle because it weirdly had the most substance.

I love this game so much. I've done so many research on ciphers just to finish this game. Definitely gave me more knowledge about ciphers. Although I'm stuck on the bible level if you can explain how it works I'd very much appreciate it.

Can't get past squares... It's the 12th word... I noticed the letter pairs are on identical position in two squares, but what am I supposed to do with that information? The hint NZ=PA is not helping...

Ads after every single puzzle, I understand free apps and don't mind small banner ads but unskippable 5+ second ads after each puzzle, some of which take less than 5 seconds themselves? No thank you.

Didn't like the clues. Also, didn't like finding out I could only see 3 add on each level right when I was stuck, and with no way to progress this game got deleted.

Great concept, and great gameplay and design. One thing to work on, is the way you answer. Just make it a little simpler and less buggy. Very smart game though.

It was fun for a short while but the Playfair cipher really threw me off since the images were abysmally unhelpful, only the third hint made it recognizable. Overall an easy game if you've studied older ciphers before but I doubt it could be educational for those who haven't since it's too unspecific at times

I'm stuck on the coordinates one the clues aren't helping I'm just more confused the grid starts with the word zodiac

It is the best time-killer I've ever had! I know this review is simple but I just love this game!Keep up the good work and please add more types of gameplay like time-attack or something like that!

The question involving modulus makes no sense for me... Do we take 'A' as 0 or 1 or 26 or 25? Do we treat negative modulus like in mathematics, or with negative sign ignored like in some programmimg languages?

Really good if you like codebreaking and encryption. I've found the hints a little vage, but you can usually find what you want by googling the name of the cipher to learn how it works.

Great game, teaches a lot. I wish that it would give a brief explanation, history, or other piece of knowledge on the tactics after solved or after using 5 hp to reveal the answer.

I've played four or five levels at the moment and I enjoy the necessity for logical thinking. The problems seems to be well done.

Cannot get past the four square cipher one even after trying to change nz with pa on each grid. The hints aren't enough information for this one.

I like the clean but also cyber/hacker visuals. In terms of riddles I was stuck in the second level so it's going to be a fun challenge.

I love it, but can't crack some of the ciphers such as the Grille. I've tried various ways with this code and I can't figure it out; plus none of the hints are helping

I'm really confused about the 5th or 6th word (I'm not too sure) I don't understand what you have to do with QBGJ

Great game! Challenging and rewarding to play. I have a few more people at work addicted to it now.

It's a very fun game. It isn't an extremely easy game which adds to the game. The visuals also look very nice and sleek.

Great game! The puzzles are difficult, but not impossible. Well done!

Help me out, stuck on Y = position

Overall, not a bad game. Definitely more geared towards people who are semi familiar with encryption/decryption methods and simple math operations (when needed). There are definitely times where the average person will be confused over the sudden change in puzzle format. For example, on one puzzle gives indexing to letters and the next shifts that indexing slightly without any inclination unless you understood how the modulo operater works. This also leads into the problem with hints. There are points, at later puzzles where I was stuck briefly, that the hints were not very descriptive and vague. For the coordinates puzzle, there is no implication on which squares and which letters are used to decrypt the cipher (which leave many combinations). The only way I was able to fully solve the problem was the last clue. Often the clues provided don't really help you understand the puzzle that's shoved at you. Usually I wouldn't be as judgemental about it, but since the app limits you on the number of hints you can get in a single question, you can be forever stuck at a level unless you brute force with the information you have. This leads me to my biggest complaint, which is that the app occasionally requires you to find/compute work. This can easily be helped if the game had some kind of calculator to use (for the modulo question). Other cases of this is the Bible question, which I'm stuck on, that requires you to exit the app to search a specific proverb. The problem with this is that there are multiple different translations of the text and that the question gives no help other than you having to brute force every word in the passage. Overall, there's some things that this app does well, but enough annoying quirks that I don't feel invested in it at all.

Fix level 1, RIFTS is a word but FIRST is the answer
