📖 What makes Bonanza Billion tick: cascades and a climbing multiplier
Classic Megaways feel: 6×7 reels with variable symbol heights, up to 117,649 ways. Any winning path triggers a cascade—winning symbols vanish, new ones drop. In the bonus, a multiplier rises with every cascade, turning an ordinary spin into a “billion” hit.
RTP is ~96%, volatility high. Dry spells happen, but when the bonus multiplier ramps and cascades keep coming, wins climb fast.
Key things to know:
- Megaways + cascades: Reel heights change; wins remove symbols, new ones drop.
- Growing bonus multiplier: In free spins it starts at 1x and climbs every cascade, with no cap.
- Retriggers: Extra scatters add spins and keep the current multiplier.
- High volatility: Sessions can be dry, but a good bonus with a cascade streak pays 300x–1000x+.
- Mobile ready: HTML5; cascades and multiplier counter work fine on phones.
The hook: any bonus spin can build the multiplier and trigger a cascade chain where each hit pays more.
🎮 How to play: megaways, cascades, and the bonus multiplier
Grid and ways
6 reels; symbol heights change each spin, up to 117,649 ways. Any winning way triggers a cascade: winning symbols vanish, new ones drop.
Bets and volatility
High volatility. I use 1–1.5% of bankroll per spin. A session can be dry, but one strong bonus with a growing multiplier covers a string of blanks.
Free spins
4+ scatters = 12 free spins. In the bonus, the multiplier starts at 1x and rises every cascade, uncapped. A retrigger adds spins and keeps the current multiplier. The key is a cascade streak.
How to squeeze the most
- Bonus chains: The longer the cascade streak, the higher the multiplier and payouts.
- Retrigger is the goal: Extra spins with a kept multiplier sharply raise potential.
- Stake to bankroll: Don’t overbet chasing the bonus; the slot can run long.
- Know when to leave: Landed 300x+? Lower stake or pause. Volatility is high.
Best hits come when the bonus multiplier ramps on early cascades and a retrigger adds spins—each subsequent win pays more.
