Bonanza Megaways slot

Bonanza Megaways is the Big Time Gaming machine that started the entire Megaways genre, with reels that scale up to 117,649 ways to win. UK arcades and pubs still run it, and the same title exists online at UKGC-licensed casinos, not through any operator we currently review. If you want that mechanic on a site we do cover, skip to the Megaways slots list further down this page and pick one from our library instead.

What is Bonanza Megaways?

Bonanza Megaways is a slot machine built by Big Time Gaming. It runs on a variable reel height: each of six reels can show two to seven symbols per spin, so the number of ways to win changes with every spin. At full height it reaches up to 117,649 ways to win, all from matching symbols left to right rather than fixed paylines.

The theme is a gold-mining setup: pickaxes, gold nuggets, dynamite and a handful of mining-camp characters sit on the reels. That part is ordinary. What made this specific cabinet matter is the engine underneath it, not the artwork.

The machine that started Megaways

Before 2016, "ways to win" slots existed, but none scaled the reel height on every spin. Big Time Gaming built that idea into Bonanza Megaways and then licensed the mechanic to other studios. That's why the word "Megaways" now shows up on titles from Pragmatic Play, Blueprint Gaming and a dozen others: they're all running a version of what this machine introduced.

Big Time Gaming later released Bonanza Gold, a sequel built around a collecting-symbols format layered onto the same reel logic. It's a different game with a different bonus round. Worth knowing if you come across it, but it isn't the machine this page is about.

Tumble featureWinning symbols removed, new ones drop in
Franchise sequelBonanza Gold (different bonus format)

Each win removes the matched symbols and drops new ones into the gaps, a tumble mechanic borrowed from cluster-pay slots. A single spin can chain several wins in a row if the drops keep landing, which is part of why the base game feels busier than a standard 20-line slot even before the bonus triggers.

The free spins feature and unlimited multiplier

Four or more scatter symbols trigger free spins. The number awarded depends on how many scatters landed. Inside the round, every tumble adds to a multiplier that keeps climbing for the whole feature. It doesn't reset between tumbles the way some other bonus rounds do, and it doesn't cap out at a fixed ceiling either. That's why a short-looking bonus round can still turn into a large payout: the multiplier does the work, not the number of spins.

Volatility: what to expect between hits

This is a high-volatility machine. The base game pays often in small amounts, and most of the return sits inside the free spins feature. Dry spells between bonus rounds are normal, not a sign the machine is behaving oddly. Anyone budgeting for a session should plan around the bonus showing up rarely and paying out unevenly when it does.

Bonanza Megaways RTP: why there's no single number

There's no one RTP figure for Bonanza Megaways. Land-based cabinets can be set within a range by the operator or venue running them, and the online version follows the same principle: the number shown depends on which configuration the site you're playing on has chosen. Quoting a single percentage here would flatten a detail that actually matters.

The way to check it properly is on the machine or game itself. Land-based cabinets carry the RTP in the help or info screen, and online versions show it in the paytable or rules panel. That's the number that applies to the spin in front of you, not an average pulled from somewhere else.

Playing Bonanza Megaways slot online in the UK

The online version of Bonanza Megaways exists, and it runs at UKGC-licensed casinos. That's a different set of sites from the ones covered on this page. We don't currently review an operator that carries this exact title, so we can't give you its verification steps, payout speed or deposit limits here, because we haven't checked them ourselves.

What we can offer instead: the same Megaways engine, built by studios working under licence from Big Time Gaming, running at operators we do cover. The list below pulls from our own catalogue rather than pointing you somewhere we haven't reviewed.

Free play: is there a demo version?

The land-based cabinet takes coins or notes only; there's no free mode on the machine itself. Online, demo play is common practice across the industry for Megaways titles, and most licensed operators let you try a slot before you register. We haven't tested demo access for Bonanza Megaways specifically on any site we cover, so treat that as something to confirm on whichever operator you choose, not a guaranteed feature.

Is there a Bonanza Megaways app?

No. There's no standalone app for this title. If you play it online, it sits inside whichever casino's own site or app you're using, alongside the rest of that operator's slot library. The same is true for the Megaways alternatives listed on this page: you reach them through the casino, not through a separate download.

How to approach stakes and sessions

Nothing here changes what a spin pays out. That's fixed by the game's math, not by how you bet. What you control is exposure:

  1. Decide the total you're willing to spend on the session before you start, not after a bonus round has already run.
  2. Check the stake range. Some Megaways slots need a minimum bet to unlock the full reel height or multiplier.
  3. If a demo mode is on offer, use it first to see the tumble and multiplier mechanics without spending anything.
  4. Note the maximum bet allowed if you're playing through a bonus with wagering attached elsewhere. That figure matters more than the headline stake.
  5. Set a stopping point for losses and for wins alike, and treat both as the end of the session.

Megaways slots you can play in our library

The machine itself isn't in our reviewed lineup, but the mechanic is. Other studios built games on the same licensed engine, with their own themes and bonus structures layered on top of the same variable reel height. The list below draws from operators we cover and games we can actually point you to.

Worth knowing

1

Check the paytable first

Land-based or online, the paytable shows the RTP setting and multiplier rules for that specific machine. Read it before you spin, not after.

2

Set a stop-loss before you start

High volatility means long gaps without a bonus round. Decide the session budget in advance so a dry spell doesn't turn into an open-ended chase.

3

Try the demo where one exists

If the operator offers a free mode, use it to see the tumble and multiplier mechanics before committing real stakes.

4

Mind the minimum stake

Some Megaways titles only unlock the full reel height or multiplier above a certain bet. Check this before assuming a small stake behaves the same as a larger one.

Frequently asked questions

Can you play Bonanza Megaways online in Australia?

Availability depends on each country's gambling rules, not on the game itself. In Britain, UKGC-licensed sites carry it online. Other markets follow their own regulator's approved list, so check what your local licence permits before searching for the title there.

What is the RTP of Bonanza Megaways?

There isn't one fixed figure. Land-based cabinets can be configured within a range by the venue or operator running them, and the online version works the same way. Check the help screen or paytable on the specific machine or site you're using for the number that actually applies.

Who makes Bonanza Megaways?

Big Time Gaming, the studio that built the variable reel-height engine in 2016 and then licensed it out. That licensing is why other studios now release their own games carrying the Megaways name.

Is there a free version of Bonanza Megaways?

The land-based cabinet takes real money only; there's no demo mode on the machine itself. Online, demo play is common for Megaways titles at licensed operators, though we haven't verified demo access for this specific title ourselves.

Which online slots play like Bonanza Megaways?

Any slot built on the Megaways engine under licence from Big Time Gaming will feel similar: variable reel height, tumbling wins, and a free spins round built around a rising multiplier. Our library list on this page points to the titles we cover with that same mechanic.

What is Megaways and how is it different from a regular slot?

A regular slot has a fixed number of paylines. Megaways changes how many symbols each reel shows on every spin, so the number of ways to win changes too, up to a set maximum. Wins come from matching symbols across reels rather than following a printed line.

Can I still find Bonanza Megaways in UK pubs and arcades?

Many venues still run Big Time Gaming cabinets, but stock varies by site and by operator. There's no single list of locations, so checking with a specific arcade or pub is the only reliable way to confirm it's there.
