20 Euros FAQ

Frequently asked questions about my game 20 Euros.


Q: The game is buggy, sometimes it won't let me add two equal coins.
A: Read the rules under the game first! For example, you can't add up two 2's to make 5, it wouldn't even make sense! To make a 5 cent coin, you have to combine two 2's and a 1.

Q: Why doesn't 2+2+2+2+2 make 10?
A: It's clearly written in the rules that at most 3 coins can merge at a time. Otherwise it would be too easy.

Q: Can I continue after winning and make a 50 Euro note?
A: Yes! You can even go all the way up to the 500 Euro note, if you can! That has actually been achieved (with an AI).


Q: Does the game have any variants?
A: The only official variant is the undo version.

Q: Can I make my own variant/fork?
A: Yes! You are free to make your own forks based on my variant, you can download it or fork it on GitHub.

A: Yes, it's here. Feel free to add comments, suggestions or further questions!

Q: Are the statistics of the game public?
A: Yes, you can find them here.
