Last updated: May 2026. Walkthrough written for first-time players landing on Bonanza Billion without any prior BGaming experience.
If this is your first time loading Bonanza Billion, the screen looks busy but the gameplay loop is one of the simplest in modern pokies. There's a 6-reel grid stuffed with gemstones, a billionaire mascot wearing a top hat, dynamite scatters tucked into the symbol mix, and a "Bonus Buy" button quietly tempting you in the corner. There are no paylines to memorise. No card-rank lines to trace. You just spin and watch for eight or more of the same symbol to land anywhere on the grid. This walkthrough takes you from "what am I looking at" to "running auto-spin on a A$1 bet" without any guesswork.

Step 1 — Pick a casino
You need an account at a licensed casino. We use four:
- Vegasnova — fastest PayID withdrawals.
- Joe Fortune — biggest welcome offer percentage.
- GreatSlots — lowest minimum deposit.
- CasinoRocket — highest stake caps for VIP play.
Any of the four works. If you're brand new, GreatSlots's A$10 minimum deposit gets you spinning with the least commitment.
Step 2 — Open the game
After depositing and claiming the welcome offer, search the casino lobby for "Bonanza Billion" or filter by BGaming in the providers list. The game tile shows the cartoon billionaire and a stack of gold coins.
Click it. The game loads in your browser (no download required — it's HTML5 and runs on any modern device).
Before you spin a real cent, click the info icon (i) in the bottom-left corner of the game. Scroll to the RTP field. It should read 96.00%. Unlike some pokies (notoriously Hacksaw Gaming's titles), BGaming does not ship reduced-RTP variants of Bonanza Billion — the 96% certified default is what every casino runs. For a full breakdown of what that number actually means in a session, see our RTP and volatility guide. If your in-game info panel says something different, that's a red flag for the casino itself, not the game; close the tab and play elsewhere.
Step 3 — Set your bet
The bet panel sits below the reels. You'll see a number — that's your current bet per spin.
- Tap the + or – buttons to step the bet up or down.
- Min bet: A$0.10 per spin.
- Max bet: A$100 per spin.
For a first session we recommend starting at A$0.20 – A$1.00. That keeps you in the game long enough to actually see a free-spins trigger (the average is roughly 1 in 200-250 spins) without burning through your deposit before the math has a chance to work.
Bankroll rule of thumb: at least 200× your bet in funds before you sit down. So a A$1 bet wants a A$200 bankroll. A A$0.20 bet wants A$40. This is a high-volatility pokie — runs of 50+ dry spins are normal. Don't enter a session under-funded.
Step 4 — Press spin
The big circular button bottom-centre is spin. Tap it once for a single spin. Press and hold to open the auto-spin menu.
What you're watching for:
- 8+ matching symbols on the grid. This game has no paylines. Symbols pay when 8 or more of the same kind land anywhere on the 6×5 grid. The card-rank symbols (10, J, Q, K, A) are low-pays. The gemstone symbols (sapphire blue, emerald green, ruby red, citrine yellow, diamond white) are high-pays. The golden billionaire is the wild and substitutes for any non-scatter symbol.
- Cascades. When a winning combo lands, those symbols explode off the grid and new ones drop in from above. A single bet can chain 3-5 cascades in a row, multiplying the spin's payout — see our cascading reels deep-dive for the full mechanic.
- Scatter symbols (red dynamite stick). Four or more anywhere trigger free spins. Don't worry about counting — the game tells you when you've hit.
Step 5 — Free spins (the bit where the bombs appear)
When 4 or more scatters land, the screen transitions into free spins:
- 4 scatters: 10 free spins.
- 5 scatters: 10 free spins + small instant payout.
- 6 scatters: 10 free spins + larger instant payout.
During free spins, the math shifts. Every winning cascade can drop a multiplier bomb onto the grid in place of cleared symbols. Bomb values: 2×, 3×, 5×, 10×, 25×, 50×, or 100×.
The bombs don't pay on their own. They sit on the grid and wait. If you trigger a winning cascade in the same free-spins round, all bombs on the grid apply their multipliers to that cascade's payout, summed together (a 10× bomb + a 25× bomb = a +35× multiplier).
Land 3 more scatters during free spins → +5 free spins retrigger. This is how a free-spins round goes from "nice little 30× hit" to "are you serious right now" 5,000× monster.
Step 6 — Stop while you're ahead
This is the rule everyone hears and no one follows. Bonus rounds in Bonanza Billion are emotional — when you've just hit a 200× round, the temptation to keep spinning is enormous because "I'm in the zone."
The math doesn't care. Each spin is independent. After a 200× win, your odds of triggering another bonus on the next spin are the same as before the first one.
Practical advice for first-timers:
- Set a session loss limit in the casino's responsible-gambling tools before you start.
- Set a session win cap — when you double your starting balance, stop.
- Use auto-spin's stop-on-win feature for the same reason.
Optional features to know about
Bonus Buy. If you don't want to wait for the natural trigger, you can pay a one-time multiplier of your stake (~100× stake for Bonanza Billion) to enter free spins directly. This is the BGaming-standard buy price — slightly higher than Pragmatic Play's typical 100× and lower than some Hacksaw bonuses.
For most players, Bonus Buy is worse value than the natural trigger over a long session (the RTP on Bonus Buy mode is typically 96.45-96.65%, only marginally better than base play, and you front-load the variance). But if you're a streamer or you have 30 minutes to play and want to skip the grind, it works.
Demo mode. Every reputable AU casino offers Bonanza Billion in demo mode for free. Try it before depositing real money. The math is identical to real-money play.
Provably fair. Click the dice icon in-game to access BGaming's provably-fair tools. You can see the cryptographic seed for each spin and verify after the fact that the spin's outcome was not manipulated. Most players never use this, but it's there if you do.
Common beginner mistakes
- Betting too high to start. A A$5 bet on a A$50 bankroll will end your session before you see a bonus.
- Auto-spinning without stop conditions. If you lose half your bankroll on auto, you can't say later "I would have stopped earlier."
- Spamming Bonus Buy. Bonus Buy at 100× stake on a A$1 bet costs A$100 per buy. Three consecutive losing buys = A$300 gone. Use sparingly.
- Confusing this with Big Time Gaming's Bonanza. Different game, different studio, different math. Don't apply Megaways strategy guides to this title. (Also note: BGaming released a sequel — see Bonanza Billion vs Xtreme so you don't mix up the specs either.)
- Chasing losses with bigger bets. Every spin is independent. Bigger bets after losses just lose more money.

Quick FAQ
How long does a session last? A A$50 bankroll at A$0.40 per spin lasts roughly 100-130 spins on average. With a free-spins trigger, it can last much longer.
Do I need to enable Bonus Buy? No — most players never use it. It's a shortcut, not a requirement.
What's the difference between cascades and free spins? Cascades happen in both base game and free spins — they're the chain-win mechanic. Multiplier bombs only appear in free spins, never in base game.
Is the demo the same as real money? Yes — same math, same RTP, same RNG. Only difference is the balance is play money.
Can I lose more than my deposit? No — slot games can't withdraw more than your balance.
How many free spins can I retrigger? No hard cap. Each set of 3+ scatters during free spins adds +5 spins. Rare to retrigger more than twice, but it has happened.
