At ZuriHac 2023, I worked on some Haskell Puzzles together with Alex, Francesco, Jussi and Patrick. You are given some Haskell tokens and a goal term, and you need to rearrange the tokens into an expression that produces the goal.
Here a simple warmup exercise just to get an idea of how it works:
Let’s continue with
iterate but do a real puzzle next. What Monad are we
How is e defined again?
let allows us to reuse code. This is very useful if you don’t have enough
tokens to make a sensible program.
Here is the final puzzle – but how can we produce a string from a bunch of numbers?
We playtested these puzzles with simple pieces of paper during the event. At the final presentation we played a web-based multiplayer version where each player controls only one token.
We actually found the single player to be more fun, and since we already had some client code I decided to clean it up a bit and make a single player version available here.
Thanks for playing!
