Haskle

Haskle is an online word-guessing game that is very captivating for all players. The game's objective is to guess a function from the preamble. Each round, you guess a function based on either its preamble or its jumbled type. At first, emojis take the place of each type element (type, binding, and type variable). Interesting, huh?

How to play

Using the mouse to move and obey commands is the problem. Using the same logic, additional guesses that reveal the function name after the type's complete revelation also reveal the characters present in both the guess name and the response name.

We have adopted the signatures almost exactly as provided by GHCI, with the following exceptions:

We use a list instead of brackets ([]).
We replace the tuples ((,) and (,)) with Tuple and Tuple3.
The function type (()) is replaced with the unit.
Typecasts for typeclass methods fall under a distinct set of constraints. Instead of (Traversable t, Applicative f) =>..., traverse, for instance, has Traversable t => Applicative f => (a -> f b) -> t a -> f (t b).

Emojis replace every character in the function name. To discover the right answer quickly, use the supporting suggestions. I wish you luck!
