Decks and Difficulty

Deck selection is the most important control for learning load in WordCraftVillage. Most consistency failures happen when learners pick a deck that is too hard too early, then try to compensate with longer sessions. A better strategy is the opposite: keep session length short, keep completion stable, and tune deck difficulty step by step.

Think of decks as load balancers. Beginner decks create momentum and confidence. Middle decks expand coverage while preserving rhythm. High decks are useful when recall stability is already strong. Moving between decks should follow data signals, not mood. Daily completion, review accuracy, and fatigue are the three signals that matter most.

1. Recommended progression order

1. Beginner: build daily completion habit and reduce hesitation.
2. Middle: expand vocabulary range after stable review behavior.
3. High: only when accuracy remains reliable under middle-level load.

This order is practical, not rigid. If you return after a long break, temporarily moving down is often the fastest way to recover retention and momentum.

2. Promotion and rollback rules

Promote one level when your recent sessions show both completion continuity and healthy review accuracy. If performance drops sharply for multiple sessions after promotion, roll back one level. This is not failure. It is controlled load management. The target is long-term retention, not short-term pressure.

3. Operational tips inside Account settings

• Check recommended route and promotion requirements before switching.
• Use manual deck switch only when your current load is clearly mismatched.
• Keep review-first policy after any deck transition.
• Avoid changing deck and language profile at the same time.
