Maybe it’s dynamic challenges that adapt to your skill level, or secret trophies that require off-beat strategies. Others integrate social leaderboards in inventive ways or tie achievements to meaningful in-game rewards. Which mobile game’s trophy hall keeps you coming back, hunting for that next badge? Do you prefer transparent progress bars or surprise unlocks?
