Current free-to-play mobile games use various mechanics to control player progression. Through the game Jelly Splash, we study three such gating mechanics: occasional spikes in level difficulty, chapter gates every 20 levels, and a limited number of lives regenerating slowly over time. Using telemetry data from a quarter-million players, we explore how players approach each gating mechanic, foc...
