Kids difficulty
Kids is the most accessible level. It is intended for younger players, early readers, English learners and adults who want a relaxed introduction. The words are more familiar and the challenge focuses on basic spelling and letter placement.
This level works well for family play and primary classroom activities because students can practice the reasoning system without being blocked by rare vocabulary.
Default difficulty
Default is the recommended starting level for most players. It provides recognizable vocabulary while still creating enough uncertainty for a satisfying puzzle.
Use Default for casual solo play, mixed family groups, general multiplayer matches and workplace activities where participants have different levels of word-game experience.
Advanced difficulty
Advanced uses less obvious words and expects a broader vocabulary. Players may need stronger pattern recognition and more careful use of the six available guesses.
It suits regular word-game players who solve Default consistently and want more rounds where the answer is not immediately familiar.
Expert difficulty
Expert is the highest challenge. It is intended for players who enjoy uncommon vocabulary, difficult letter combinations and the possibility of needing a clue.
This level can be demanding in multiplayer, so use it when all participants understand that an unfamiliar answer is part of the challenge rather than a mistake in the game.
How to choose the right level
Start with the level where most answers feel possible but not automatic. If nearly every round ends in one or two guesses, move up. If players regularly fail because they do not recognize the final word, move down and build confidence.
Mixed-age groups can use Kids or Default, while competitive groups can agree on Advanced or rotate levels between rounds.
Separate progress for each difficulty
Wurdella keeps difficulty progress separate. This means an Expert experiment does not erase or confuse results earned in Default, and players can compare their performance within a fairer context.
