RTP (Return to Player) is generally a reliable indicator, especially when you're playing at licensed and regulated online casinos. These platforms are required to use certified software with transparent RTP rates. However, some shady or unlicensed sites might tamper with game settings, so it's important to stick with well-reviewed, trusted operators. Personally, I’ve had heaps of wins on games with solid RTPs, but I always double-check the casino's credentials before playing. Better safe than sorry!
