Base Game Mechanics
Like Gates of Olympus, Sweet Bonanza uses a tumble mechanic: winning symbols are removed and new ones fall from above, potentially creating chain reactions of consecutive wins from one paid spin. Wins require clusters of at least 8 matching symbols anywhere on the grid.
Symbol values are divided into two tiers:
- High-value symbols: Heart, grape, watermelon, plum — require fewer in a cluster for meaningful payouts
- Low-value symbols: Apple, banana, and sweets — more common, smaller returns
The Bomb/Multiplier Symbols
Scattered across the reels are bomb (×) symbols that carry multiplier values (×2, ×3, ×5, ×10, ×25, ×50, ×100). These do not form part of winning clusters themselves. Instead, when they appear anywhere on the reels during a win, their values are applied to that win. If multiple bombs appear in the same tumble, their multipliers are multiplied together — not added — which is distinct from some other games.
Free Spins Bonus
The bonus round is triggered by landing 4 or more scatter symbols (the lollipop/candy scatter):
- 4 scatters = 10 free spins
- 5 scatters = 12 free spins
- 6 scatters = 15 free spins
During free spins, multiplier bombs appear far more frequently than in the base game. Crucially, multiple bombs in a single tumble multiply their values together rather than adding — so two ×10 bombs produce a ×100 multiplier on that win. This is the mechanism behind the game's outsized win potential.
Free spins cannot be retriggered in standard mode, though a "buy feature" (where available by jurisdiction) allows direct purchase of the bonus round.
Buy Feature
In jurisdictions where it is permitted, Sweet Bonanza offers a bonus buy option that costs 100× the current bet and immediately triggers the free spins round. This is not available in all markets and is restricted in some regulated territories (including the UK). Buying the feature does not improve the odds of the bonus round itself — it simply skips the base game stage.
RTP Variants
Pragmatic Play offers Sweet Bonanza in multiple RTP configurations. The published standard is 96.51%, but lower-RTP versions (as low as around 88%) exist and may be deployed by some operators. Always check the in-game info panel to confirm the RTP of the version you are playing.
What to Expect in Practice
As a high-volatility game, Sweet Bonanza is designed to deliver infrequent but potentially larger wins. The base game can produce many consecutive losing spins. The majority of the game's theoretical return is weighted toward the free spins bonus, which itself can range from minimal to very large depending on bomb frequency and clustering. No session is "due" a bonus — each spin is independent.
