I really enjoyed this game, right up until I ran out of advanced puzzles. Now I can't even start an advanced game. It would be great if more complicated types of ciphers were added!

T70%
by T####:

If NSA created this app, I'd say you guys are awesome! The puzzles are really hard to decode! How can you possibly decode this when certain letters from keyboard are missing! Nice job! GREATEST app of all time!

F70%
by F####:

You should change it to use the phone's default keyboard, the in app one is cut off, there are no P or L keys.

T70%
by T####:

Two letters were missing on keyboard P and L. If you are going to leave out letters L isn't the best choice

C70%
by C####:

I wish there was a more challenging difficulty level though.

Z70%
by Z####:

Great app with the most horrible bug!

U70%
by U####:

No P or L on keyboard! Can't use default keyboard, makes the game useless !!!

I70%
by I####:

Fix the keyboard and this will be fun.

C70%
by C####:

Well, it looks like they don't care about the bugs, so I don't care about the game, so, I decided to uninstalled. Bye, bye!...learn to listen the costumers and have a good life.

C70%
by C####:

The game is challenging. Perhaps you could use foreign languages to decrypt to make it harder.

C70%
by C####:

P, L and CLEAR missing on the keyboard. Can't complete the game. Can you pls fix this

T70%
by T####:

I like this game great puzzle, but the keyboard doesn't have P or L making some of the puzzles unsolvable.

V70%
by V####:

Good game but letters p and l are missing from keyboard

X70%
by X####:

Missing letters. Numb nuts.

C70%
by C####:

No p or L. Can't solve without ALL the letters!

C70%
by C####:

This app doesn't respond at all.

L70%
by L####:

The keys p and L are missing. In your keyboard

C70%

No "p" or "L" keys.

C70%
by C####:

Interesting

C70%
by C####:

I like this game but my game keyboard is missing a 'p' and there's no clear option. Its not my keyboard as i have those things, and it looks like I'm not alone.Fix this and then ill give it the other star. Also it'd be nice if you explained the difference between the levels. I was done with a whole puzzle in intermediate before i realized why it was harder than beginner

H70%
by H####:

Please fix this and so I can complete decryption. A puzzle without all the pieces is trash.

M70%
by M####:

No P or L keys. I assume there's some sort of clever NSA crypto reason for this because otherwise it's just unthinkable incompetence, but all I wanted was a few puzzles. I'll try elsewhere. Uninstalling.

M70%
by M####:

Missing "P" and "L" keys making the game unplayable and broke

K70%
by K####:

Liked the Crypto puzzles, the only issue is the key board is missing the P and N . Fix this so the Times for solving can be accurate.

N70%
by N####:

Hard to solve any puzzles without the p or l keys, most of my puzzles have had at least one or two errors because of these missing letters.

Q70%
by Q####:

I so wanted to play but the "p","l", and "clear" are missing and I can not complete a puzzle.

M70%
by M####:

Really good app,however my keyboard is missing a P so I have to use hints to beat the codes,kind of unfair.

M70%
by M####:

Can we have "P" and "L" button so that we can play

W70%
by W####:

Missing letters on the keyboard

M70%
by M####:

For our security NSA.
