Library depth is the headline metric

The casinos we operate carry between roughly 6,500 and 8,000 titles each, drawn from dozens of studios. Size alone is not everything, but a deep library from serious studios means you get the current hits, the high-volatility releases and the Megaways titles rather than a thin catalogue of filler.

RTP and volatility

RTP (return to player) is the long-run theoretical payout percentage of a slot - 96% and above is healthy. Volatility describes how the wins are distributed: high-volatility slots from NoLimit City or Hacksaw pay rarely but large; low-volatility slots pay often but small. Note that some operators run the same game at different RTP configurations - we flag this where we find it.

Megaways and bonus-buy

Megaways, licensed from Big Time Gaming, changes the number of ways to win every spin. Bonus-buy lets you pay to trigger a slot's feature round directly. Both are popular and both are higher-variance - treat them accordingly.
