From “Got It” to “I’ve Got This”: Designing Challenge and Mastery That Stick

In my last piece I argued that first impressions decide whether someone sticks around. A slick UI or a clever feature can win that first look, but it is mastery that earns the return visits.

The principle is simple. People stick when challenge and skill are in balance. Too easy and they drift away. Too hard and they quit. Get it right and you unlock loyalty, frequency, and willingness to pay. Psychologists call this the flow state.

Think about the moments when you feel yourself leveling up. It might be surviving a tough lane in League of Legends, finally nailing a verb tense on Duolingo, or realizing Superhuman really did cut your inbox time in half. That satisfaction is cognitive fun. It is the joy of learning, progressing, and getting better.

Let’s dig into how four very different products have built mastery into their DNA.

What Is Cognitive Fun

Cognitive fun is the satisfaction of getting better at something. It is the invisible current that carries you from “I do not get this” to “I have got this.”

Every product that survives long term uses some version of this loop:

Expose → Attempt → Feedback → Adjust → Proof of progress

The loop is universal. What changes is the size of the challenge, the speed of the feedback, and how clearly progress is shown. Memory science backs this up. Without reinforcement we forget quickly, but structured practice and spaced repetition slow that decay.

Case Study: League of Legends

Riot’s League of Legends has been running for over a decade, and its Champion Mastery system is a big reason why. Players earn mastery levels with each champion based on performance, results, and match length.

Why it works

• There is always a nearby win state. Even if you lose, you still collect points.

• Visible progress matters. Post match grades and mastery levels confirm improvement.

• Ambition rises naturally. Once you master a champion, the ranked ladder offers the next challenge.

The caution here is grind. In 2024 players pushed back on mastery reworks that felt like chores instead of growth. Mastery has to move with skill.

KPIs to watch

• Percentage of users reaching their first mastery milestone in the first week

• Conversion from casual play to ranked or advanced play

• Feedback latency. If learning takes longer than a single session, you risk losing players

Case Study: Honor of Kings

Tencent’s Honor of Kings (Arena of Valor in the West) is one of the most profitable games ever, and its mastery design is a blueprint for mobile.

Why it works

• Matches are short. Fifteen to twenty minutes delivers quick feedback.

• Layered difficulty starts simple and grows deeper with ranked tiers and hero builds.

• Persistent progress keeps players invested with hero levels and gear growth.

The numbers tell the story. Mobile games reached over 100 billion dollars in revenue in 2025 with three billion global players. Retention benchmarks sit around day one at 35 percent, day seven at 20 percent, and day thirty at 10 percent. Honor of Kings consistently beats those numbers because it combines quick loops with long term mastery.

KPIs to watch

• Percentage of players advancing from novice to ranked within two weeks

• Average time to first rank up moment

• Retention segmented by mastery tier

Case Study: Duolingo

Duolingo has turned language learning into one of the best examples of mastery loops outside of games. Its streaks, leagues, and repetition system keep people coming back every day.

Why it works

• Micro challenges keep sessions short and approachable.

• Feedback is instant. Right or wrong is clear with no delay.

• Spaced repetition brings back words right before you are likely to forget them.

• Visible progress through streak counts, XP, and leagues builds emotional investment.

The numbers are staggering. Forty million daily users, more than ten million with streaks lasting a year, and a DAU to MAU ratio of thirty four percent.

KPIs to watch

• DAU to MAU ratio

• Lesson completion velocity

• Distribution of streak lengths

Case Study: Superhuman

Superhuman takes a different approach. Instead of gamifying a mass audience, it focuses on one-to-one coaching. New users get paired with a real human coach for a thirty-minute session that uses their actual inbox.

Why it works

• Feedback is high bandwidth and immediate.

• The payoff is instant. You leave feeling faster within minutes.

• Confidence spikes because you are not just competent but empowered.

Superhuman claims this onboarding cuts email time in half, and the fact that people are willing to pay a premium price for email proves mastery is valuable.

KPIs to watch

• Time to competence, meaning how fast someone can work unassisted

• Percentage of users who finish setup in the first session

• Behavioral outcomes like emails processed per hour before and after onboarding

Side by Side Comparison

Pitfalls to Avoid

• Grind without growth. If users do not feel smarter or more capable, points and badges feel empty.

• Flat difficulty. A single level of challenge turns off both beginners and experts.

• Opaque progress. If users cannot see what they are improving, they will not stick around.

The Playbook: How to Design Mastery Into Your Product

Design moves

• Progressive disclosure. Unlock features when the user is ready.

• Calibrated challenges. Always keep one attainable goal in reach.

• Tight feedback cycles. Under two seconds is the sweet spot.

• Visible progress. Use badges, levels, streaks, or clear metrics.

• Spaced reinforcement. Bring back skills before they fade.

Team metrics to track

• Day seven and day thirty retention

• Time to first competence

• Promotion funnel from one tier to the next

• Feedback latency

• Reactivation lift from targeted prompts

Closing Thought

Onboarding gets you the first yes. Mastery earns you the second, third, and hundredth.

The best games, apps, and SaaS products all keep skill and challenge in sync. Mastery makes people proud. And once someone feels proud, you are no longer just delivering a product — you are part of their identity.

Next time we will look at how social fun turns that pride into belonging.
