## What is Cryptex?

How many riddles can you solve?
Open the cryptex and find out whether you're a genius!

Let your imagination run and find the logic behind 60 mysterious riddles. Every right answer opens the cryptex and leads you on to the next stage.

The riddles are divided into 5 levels of rising difficulty. 90% of people can solve the first level. Only 5% make it through the last one. Where do you stand?

FEATURES
• 60 unique riddles: numbers, patterns, shapes and wordplay
• 5 levels of rising difficulty
• 120 hints, and the solution when you are really stuck
• IQ score that changes as you play
• Stars for every riddle and detailed statistics
• 28 languages

HOW TO PLAY
Study the riddle, set the answer on the rollers of the cryptex and press CHECK. Every riddle has two hints, but each hint you use lowers the IQ you earn for it. Solve it on your own to get all three stars.

Your IQ is measured throughout the game, so you can see how sharp your mind really is. It is a game, not a clinical test, but it is a great workout for logical thinking and memory.

For everyone who loves puzzles, brain teasers, logic riddles, math puzzles and mind games.
