Based on thePlaylinerresearch, here is a guide to designing difficulty:
1. Offer multiple difficulty tiers • Easy, Hard, Super Hard — with clear visuals to indicate the level.
2. Use attempts, not win rate, to tune difficulty • Low attempts (1–3) = Easy • High attempts (20–35) = Hard
3. Follow a recommended difficulty curve • Start easy (Levels 1–20) to build confidence • Add a hard spike (Levels 20–30) to create challenge • Introduce progressive increases and major paywalls after Level 50
4. Gradually introduce mechanics • Let players master core gameplay before adding complexity.
5. Reward wisely • Scale rewards with difficulty. Tougher levels should yield better prizes.
6. Test and iterate • Track completion rates. • Adjust blocker levels. • Fine-tune using player feedback. • Alternate between challenging and easier phases. Make the game feel “just challenged enough” to keep trying. Good puzzle design isn’t just about difficulty — it’s about balance.
