Narcos — RTP 96.23%
Play’n GO
Play’n GO develops high-volatility games with immersive themes and solid bonus-round structures.

Higher-RTP games generally provide more consistent returns, while volatility determines whether wins are frequent or more sporadic but larger. Selecting a theme you enjoy also makes the experience more engaging, especially when testing a game for the first time. For example, if you’re not a horror fan, skip the scary slots!
