A Goldmine Adventure at a Steady Pace
Bonanza's reels are dressed in pickaxes, lanterns and gemstone ore, leaning into a goldmine adventure setting rather than anything flashier. Big Time Gaming rates it medium volatility, which in practice means the base game keeps ticking over with smaller returns instead of long dry stretches, while the bonus round is where the bigger numbers tend to show up. If you'd rather browse the wider Big Time Gaming and NetEnt line-up first, the Slots Guide groups every title on the site by pace so you can see where Bonanza sits before you commit a session to it.
What the Bonus Round Actually Changes
Bonanza carries a confirmed bonus round, and it plays differently from the base spins: instead of the usual grid, the round shifts the game into its bonanza-style free-spin mode where wins can stack in ways the regular reels don't allow. That's the whole appeal of a medium-volatility title like this one — you're not waiting through a flat base game hoping for one big feature, the smaller wins along the way keep the session moving while the round does the heavier lifting. At 96% RTP, Bonanza lands right at the median for the slots covered on this site, so it's neither a standout nor a laggard on raw return — it's a fair, middle-of-the-pack number to plan around.
I'd rather see a game state its RTP plainly than dress it up, and 96% next to a confirmed bonus round is exactly the kind of pairing I look for before recommending a medium-volatility pick.

The Bonus Buy Option, With a Budget Reminder
Bonanza also lists a bonus buy, letting you pay directly for a shot at the round instead of triggering it through base play. That's a real cost decision, not a shortcut — set a budget for the buy before you use it, and if you're playing under any active wagering requirement, check that a bonus buy purchase actually counts toward it first. A bonus buy inside a slot is a separate mechanic from any casino promotion, so it's worth treating the two as unrelated spends.
Bonanza vs. Apollo Pays: Same Studio, Different Pace
If Bonanza's medium volatility feels too gentle, Apollo Pays is the sibling to try. It's another Big Time Gaming title, but it's rated high volatility rather than medium, trades the goldmine setting for a Greek mythology theme, and doesn't carry Bonanza's confirmed bonus round or bonus buy in its own listing. For players who want the dynamic reel format without switching studios, Buffalo Rising Megaways is a medium-volatility option from Blueprint Gaming that also lists a bonus buy alongside its Megaways mechanic.
I'd start a session on Bonanza if I wanted steady, watchable pacing, and save Apollo Pays for a night when I'm fine with longer gaps between bigger swings.
Before You Try the Bonus Buy
Bonanza's bonus buy only makes sense once you've got an account funded and ready. If you haven't set one up yet, the Login & Registration page walks through the sign-in and registration steps in order, including when identity verification actually happens, so you know what to expect before your first session.
