How a Kryzzle clue works
- Read
The clue is printed in cipher. At first it looks like nonsense.
- Decode
Spin the cipher wheel until the letters snap into English.
- Fill
Now it is a normal crossword clue. Solve it and fill the grid.
Try it. Spin the inner ring, the answer has 3 letters.

Cracked. That is the whole game, eleven more ciphers deep.

The decoder
A cipher wheel, reference charts and keyword sliders slide up as a companion sheet while you solve. Use it every time, or wean yourself off and read code straight.
A puzzle a day
One new daily from a 365-puzzle pool. Streaks are kept, and defended.
Every solve pays coins
Start with 400, earn more per puzzle, no cap. Spend them on hints or table styles that repaint the game.
Nothing interrupts
No banners, no pop-up ads, no tracking. A short video plays only when you ask for bonus coins.
No account
Nothing to sign up for. Progress backs up quietly to your own iCloud.
Coins, not paywalls.
- Every puzzle you solve pays. Hints cost coins, and solving is the main way to get them.
- Spare coins buy table styles that repaint the whole game, decoder wheel included.
- Coin packs exist if you would rather not wait. No subscription, ever.
The whole campaign is finishable without spending anything. Your streak cannot be bought back, on purpose.
By the last chapter, you will just read secret code.
That is the magic. Free to play, fully offline, no account, nothing interrupts.
