1. About the Game

This case study focuses on a Mobile Word Puzzle Game that challenges users to form words from a jumbled letter bank. The game appeals to casual and educational gamers, targeting vocabulary lovers and brain training app audiences.

2. The Challenge

Monetization Drop-Off: Average session time was under 3 minutes, limiting ad impressions
Hint Fatigue: Users were reluctant to use paid hints, affecting IAP sales
Low Repeat Play Rate: D7 retention hovered around 9%, with few long-term loops
Ad Blindness: Banner and interstitials had weak CTR and poor eCPM

3. Strategy / Solution

Rewarded Utility Integration

Replaced hint button with a “Watch to Reveal Letter” rewarded ad
Added “Word Multiplier” rewards: watch ad to boost score from correct guess
Weekly challenge completion now unlocks a bonus round via rewarded video
Introduced optional “Shuffle Boost” after failed attempt, powered by ads

Gamified Habit Loops

Daily Streak Counter with ad-boosted rewards on day 3, 7, and 14
Introduced “Word Bank Collection” meta-progression (collect rare words to unlock themes)
Implemented weekly leaderboard powered by Adjoy-sponsored tournaments
Push notifications tailored to language learners and streak restorers
