Frequently asked questions

How does the quiz work?

Each question shows a word written in a code, with four options. Pick the code you think it is, read the short clue, and move on. A quiz has ten questions and takes a couple of minutes.

Do I need to decode the word?

No. You only have to name the code. Each answer tells you what the word says, in case you are curious.

Are the questions random?

Yes. The order, words and wrong answers change every time, so you can play again and again.
