A new SlotsRanker study reports that mobile devices have decisively overtaken desktop computers for real-money slot play, marking 2025 as the first truly “mobile-first” year in online gambling. SlotsRanker is a trusted, data-driven resource for the global iGaming community. Our team of analysts tracks real-money slot performance across licensed jurisdictions, delivering actionable insights to operators, studios, affiliates, and players alike.

- Mobile devices account for about 80 % of all online gambling activity worldwide in 2025, up sharply from roughly 60 % just one year earlier.

- Operators tracked by SlotsRank report 74 % of slot spins occurring on mobile during a title’s first 14 days—up from 65 % in 2024.

- Total mobile internet traffic has grown 295-fold between 2012 and 2025, providing the bandwidth needed for richer slot features such as cascading reels and real-time jackpots.

- Market analysts project the mobile gambling vertical will reach US $173 billion by 2030, reflecting a compound annual growth rate above 10 %.

What the shift means for developers and operators

- Prioritize portrait layouts and thumb-friendly controls to match the way players now hold their devices.

- Cut initial load times below three seconds; players abandon slowly loading titles at far higher rates on mobile connections.

- Integrate frictionless payments such as biometric wallets and one-tap crypto to keep play truly on-the-go.

- Leverage push notifications and lightweight live-ops events; mobile users respond well to time-boxed promotions they can join between daily tasks.

SlotsRank expects mobile share to climb another 3-4 percentage points by year-end as 5G coverage expands in emerging markets and younger cohorts enter legal gambling age.
