Sweet Bonanza is one of Pragmatic Play's most-streamed pokies globally, and the mechanic behind its 21,175x ceiling — rainbow bomb multipliers that stack by addition, not multiplication — trips up a lot of players who assume they compound like Gates of Olympus orbs. I tested it at Johnny Kash to break down exactly how the maths works.
How do the bomb multipliers actually combine?
Wins land on 8+ matching symbols anywhere on the 6x5 grid, tumbling after each hit the same way most modern Pragmatic titles do. Rainbow bomb multiplier symbols, valued 2x to 100x, appear only during free spins — and they're non-sticky, meaning they don't persist from spin to spin the way Gates of Olympus's global multiplier does. Instead, when multiple bombs land on the same spin, their values are added together, then that combined total is applied to all wins on that single spin. Three bombs of 25x, 50x and 100x sum to 175x — that's the mechanism behind the big numbers, not a running accumulation across the whole bonus round.
Base-game hit rate sits around 22%, meaning roughly 1 in 4.5 spins produces any win at all — noticeably drier than Sugar Rush's 34.48%. Free spins trigger on 4+ scatters (10 spins), 5 scatters (12 spins) or 6 scatters (14 spins), and in the original Sweet Bonanza these aren't retriggerable — once you're in, that's the full bonus length.
| Bomb combination | Combined multiplier | Notes |
|---|---|---|
| Single 25x bomb | 25x | Most common single-bomb outcome |
| 25x + 50x | 75x | Two bombs landing on the same spin, added together |
| 25x + 50x + 100x | 175x | Rare — this is the scale of combination behind the 21,175x ceiling |
The additive climb looks almost linear here — a useful reminder that it's addition, not compounding.
Author's tip from Chloe Summers, Lottery & Bingo Specialist: "Don't expect bomb multipliers to persist like Gates of Olympus orbs — they're additive within a single spin, not accumulating across the whole bonus. A big win needs several bombs landing together, not several separate spins building up."
Is the original worth it, or should you go straight to Sweet Bonanza 1000?
Sweet Bonanza 1000 raises the ceiling to 25,000x with a 1,000x multiplier cap per bomb, compared with the original's 21,175x and 100x cap — same theme, same core mechanic, meaningfully higher potential. If you're deciding between the two, the original has the longer track record; the 1000 version has the bigger number for essentially the same base RTP range.
An Ante Bet option adds 25% to your stake for double scatter frequency — at a A$1 base bet, that's A$1.25 per spin for roughly twice the chance of triggering free spins. Bonus buy at 100x is available at some AU casinos but isn't universal, so check before depositing specifically for that feature.
18+ only. A 22% base-game hit rate means dry stretches are the norm here, not the exception — plan your session length around that, not around the headline multiplier.
