Mobile game developers build, ship, and live-operate games on Android and iOS — from hyper-casual titles that acquire users at ₹2-8 CPI to real-money gaming (RMG) platforms where a single tournament event can drive ₹10Cr+ in a weekend. In India, the role concentrates at RMG studios (Dream11, MPL, Games24x7, Adda52, Junglee Games now under Flutter Entertainment, Zupee), hyper-casual publishers (Nazara, InMobi Games, Moonfrog, Hike Games), and the mid-tier product studios (SuperGaming, Octro, JetSynthesys) that ship across multiple genres. Daily work spans Unity C# or Cocos2d gameplay code, Google Play Billing and Apple IAP integration, ad mediation (AppLovin MAX, IronSource, Unity Ads), Firebase + GameAnalytics event instrumentation, live-ops feature delivery (tournaments, seasonal events, battle passes), A/B testing monetization flows, App Store Optimization (ASO), and — for RMG studios — TNGRA compliance, state-level regulatory blocks, and KYC/TDS integration for prize payouts. Mobile gaming is India's largest game segment by revenue and headcount, with the 28% GST headwind creating instability in RMG but no parallel slowdown in hyper-casual or mid-core mobile.
