What’s the difference between Journey, Rush, and Survival?
Journey is the structured campaign: 5 tiers (Beginner to Master) × 10 levels × 8 puzzles each. No timer, unlimited retries per puzzle. This is the only mode that affects your puzzle rating.
Rush: beat the clock: ends after 3 mistakes or when time runs out. Difficulty adapts to your performance as you go.
Survival: like Rush but untimed: keep solving until you make 3 mistakes. Tests endurance, not speed.
