Small details and animations enhance the classic game without losing that classic paper feel. It's your mind versus the witty, wise or obscure quote. The game works in any orientation, and purposefully avoids distracting timers. Just in case you get stuck, there is an option to show yourself a hint (and we're not counting). With 15 puzzles included, CryptoQuip will keep your brain engaged for hours. If you want to play more you can buy 1000s of puzzles right inside the game. You can also turn off all the ads through in-app purchase. The game takes advantage of newer iOS features and layou, but also works well on older devices running iOS 9.3. Happy code cracking!
