This is a page dedicated to puzzles, ciphers and brain teasers I made for summer camp (for older children to solve) or for friends. Some of them were taking part in some bigger game, those are usually easy to solve. Some of them, however, are harder to solve. Puzzles from this category were usually pinned on board for several days, and whoever solved them, earned extra points for their team.
Contents of these ciphers/puzzles are usually messages in Czech language. All ciphers are marked with a flag (Czech, English or "universal") and difficulty rating. You can validate your solve results using validator under every puzzle - it's not case sensitive, removes Czech diacritics and tolerates absence of spaces, where appropriate. If you think you solved the puzzle right, but validator still tries to tell you, that you're wrong, contact me via email: kenny (at) cetes (dot) cz.
For solving, you may need standard english alphabet (26 letters) with corresponding numbers (A -> 1, B -> 2, ...), Morse coding table, paper, pen, and usually a clear mind, since these puzzles are often based on a very simple thought. Remember, kids solved them all.
Good luck.
