RTP (Return to Player) refers to the proportion of all wagered money that a slot machine is projected to return to players over time. A slot with a 97% RTP provides an average payout of ₹97 for every ₹100 wagered, based on millions of spins. Generally:
- Low RTP: < 95%

- High RTP: 97% or higher
The higher the RTP, the greater your chances. Let’s take a look at the top slot games in 2025 in terms of RTP.
