RTP vs volatility: the two numbers that actually matter
Return to Player (RTP) is the long-run percentage a slot is designed to return. Regulators describe how the advertised theoretical RTP is monitored against the actual RTP observed in live play, and why variance means short-session results can swing widely before converging.
Volatility (also called variance) describes the distribution of outcomes: low volatility…

What is a “Bonus Buy” in online slots?
A Bonus Buy (also called “Buy Feature” or “Buy Free Spins”) lets you pay a fixed multiple of your current bet to trigger a slot’s bonus round instantly, instead of waiting for scatters to land. Many modern titles advertise this directly in their game pages and rules.
How much does a Bonus Buy usually…
What “volatility” means in slot games
Volatility (often called variance) describes the risk profile of a slot’s payouts: high-volatility games tend to produce fewer wins on average but the wins can be much larger; low-volatility games hit more often but typically pay smaller amounts. This is distinct from Return to Player (RTP), which is the long-run average percentage a game pays…
Why provably fair matters for Bitcoin slot fans
Provably fair systems let you verify each game round using hashed server results plus your client seed, so neither you nor the casino can manipulate outcomes.

Progressive jackpots pool a portion of every qualifying wager so the top prize climbs until someone hits it, then the pot “reseeds” to a minimum and grows again. Online slots link thousands of games across a network, which is why headline wins regularly reach seven and eight figures.
For crypto players, the practical question is payout currency. Major networks seed and…

One-paragraph verdict
Mega Moolah remains the internet’s most famous progressive slot for a reason: a simple 5×3, 25-line game bolted to a four-tier jackpot that has paid eight- and even nine-figure equivalents in fiat. The trade-off is a lower base RTP than regular slots, but if your goal is a shot at life-changing money, this network still delivers—and yes, at crypto-friendly…

Read this first: what “RTP” means in practice
Return to Player (RTP) is the long-run percentage a slot is designed to pay back; it’s monitored by regulators and shown in a game’s help/info screen. It’s an average over many spins, not a promise for any session. In the UK, the regulator even runs live RTP performance monitoring and expects the RTP…
