How is this different from Wordle?

Wordle hides a single secret word; Hash hides a transformation rule. In Hash you feed the function inputs and read the outputs to deduce what rule it follows · the answer is a function, not a word.

What kinds of rules appear?

Easy uses Caesar shifts (each letter advances by N) and mirroring. Medium adds vowel/consonant-conditional rules (e.g. "vowels advance, consonants don't"). Hard uses positional math · index-conditional rules (the rule depends on whether the position is even or odd, or on the position itself) and arithmetic transformations of the alphabet positions.

How many tests do I get?

Up to ten tests per round. The fewer tests you use to crack the rule, the higher you score. The optimal strategy isn't random sampling · it's designing inputs that discriminate between competing hypotheses. The same skill underpins effective debugging and good experimental design.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App.
