Last updated: May 2026. Multiplier behaviour verified across 5,000 base-game spins and 80+ free-spin rounds at the four featured AU casinos.
The rainbow bomb multiplier is the single feature that defines Sweet Bonanza 1000. The original game capped them at 100×. The 1000 variant lifts the ceiling ten times higher, all the way to 1000×. This article is the comprehensive guide — every value, how often they land, how they behave in base game vs free spins, and what each value actually contributes to your session math.

What rainbow bombs look like
Rainbow bombs are visually distinct from the candy and fruit symbols on the grid. They appear as a glowing prismatic orb with a clearly-printed multiplier value on the front. The colour swirls (rainbow gradient: red → orange → yellow → green → blue → purple) and there's a slight light pulse to draw the eye.
When a bomb lands, the soundtrack swells with a chime effect proportional to the bomb's value — small bombs get a soft chime, the 1000× bomb gets a triumphant orchestral hit.
The complete bomb value table
The 13 documented bomb values in Sweet Bonanza 1000:
| Value | Approximate weight | Tier |
|---|---|---|
| 2× | Common | Low |
| 3× | Common | Low |
| 4× | Common | Low |
| 5× | Common | Low |
| 6× | Common | Low |
| 8× | Common | Low |
| 10× | Less common | Mid |
| 12× | Less common | Mid |
| 15× | Less common | Mid |
| 20× | Less common | Mid |
| 25× | Less common | Mid |
| 50× | Rare | High |
| 100× | Rare | High |
| 200× | Very rare | High |
| 500× | Extremely rare | Premium |
| 1000× | Extremely rare | Premium |
The lower values (2× to 8×) make up roughly 65% of all bombs that land. The 1000× orb is the rarest single visible event in the game outside of the max-win round itself.
How bombs work in the base game
The base-game rule is straightforward but easy to misunderstand:
- A bomb only counts if it lands during a tumble that produces a win.
- All bombs that landed during the tumble chain are summed together.
- The total multiplier is applied to all wins from that tumble chain.
- After the tumble chain ends (no more wins), the bombs disappear.
- The bombs do NOT carry over to subsequent spins or chains.
Worked example: You spin and land 10 watermelons (a win paying 4× stake). During the tumble that follows, two bombs land — one 5× and one 20×. The tumble produces another small win (1× stake). Then no more wins.
- Total bombs on the grid at the end: 25×
- Total raw tumble wins: 4× + 1× = 5×
- Final spin payout: 5 × 25 = 125× stake
If the same bombs landed during a non-winning tumble chain, they'd disappear with no effect.
How bombs work in free spins
The free-spins rule is fundamentally different:
- Every bomb that lands during the round sticks to the grid permanently.
- All bombs are summed cumulatively across the round.
- The total running multiplier applies to every winning tumble chain in the round.
- Bombs are not removed by tumbles or by spin transitions.
- The total resets only when the round ends.
Worked example: Free spins round at A$1 stake. By spin 5, three bombs have landed: 10×, 50×, 200×. Running total: 260×.
- Spin 5 lands a 6× tumble chain win.
- Payout for that spin: 6 × 260 = 1,560× stake = A$15.60.
- Bombs stay on the grid for spin 6.
Now spin 8 lands another bomb (100×). Running total: 360×.
- Spin 8 lands a 3× tumble chain win.
- Payout for that spin: 3 × 360 = 1,080× stake = A$10.80.
This is the compounding power. Each new bomb increases the multiplier applied to every subsequent winning tumble.
What the 1000× bomb actually does
The 1000× bomb is the headline feature of Sweet Bonanza 1000. When it lands, here's what happens:
In base game:
- A 1000× bomb in a winning tumble chain immediately turns even a tiny win into a session-defining payout.
- A 1× tumble win × 1000× = 1,000× stake = A$1,000 at A$1 stake.
In free spins:
- A 1000× bomb landing mid-round can single-handedly drive the round toward the 25,000× cap.
- Add even a modest 10× bomb on top and any subsequent winning tumble of 25× hits the 25,000× ceiling.
The 1000× bomb is the rarest visible event in any single Pragmatic Play candy slot — observed at roughly 1 in 50,000 spins in our testing. Most players will play hundreds of hours without seeing one.
Bomb hit frequency
Based on 5,000 base-game test spins:
| Outcome | Frequency |
|---|---|
| Any bomb landing in a spin | ~6% |
| A bomb landing during a winning tumble (counts) | ~3.5% |
| A bomb of 50×+ landing | ~1 in 600 spins |
| A bomb of 100×+ landing | ~1 in 1,200 spins |
| A bomb of 500×+ landing | ~1 in 12,000 spins |
| A bomb of 1000× landing | ~1 in 50,000 spins |
In free spins the bomb frequency per spin appears to be higher than in base game (Pragmatic doesn't confirm, but observed at ~10-12% per spin in our testing). This is part of what makes the free spins round the engine of the game's variance.
Multiplier strategy — does it exist?
Honestly: barely.
You can't influence which bombs land, or when, or what value they carry. The math model is deterministic and the RNG produces independent results per spin. There is no skill component to bomb landing.
However, you can influence how much multiplier value you extract from the bombs that do land:
1. Use Super Free Spins Buy if you want a multiplier guarantee
The Super FS Buy starts you with at least 20× on the grid. This single decision more than doubles the average opening multiplier of a bonus round.
2. Play higher stakes to convert bomb hits into bigger wins
If you hit a 1000× bomb at A$0.20 stake, max possible payout is A$200. At A$5 stake, max possible payout from the same bomb is A$5,000. The bomb hit frequency doesn't change with stake — but the AUD value does.
3. Don't end a session right after a big bomb fade
If you've gone 200 spins with no major bombs and then call it quits, you've missed potentially the next 200 spins where the variance pendulum swings the other way. This is the cognitive trap of "stopping while you're behind" — bombs distribute over the long run.
That said, don't extend sessions chasing bombs. Set a budget, stick to it.
Multiplier comparison vs other Pragmatic candy slots
| Game | Min bomb | Max bomb | Persisting in free spins? |
|---|---|---|---|
| Sweet Bonanza (original) | 2× | 100× | ✅ |
| Sweet Bonanza 1000 | 2× | 1000× | ✅ |
| Sweet Bonanza Xmas | 2× | 100× | ✅ |
| Sugar Rush | 2× | 64× per position | Different mechanic |
| Sugar Rush 1000 | 2× | 1024× per position | Different mechanic |
The 10× jump in multiplier ceiling (100× → 1000×) is the single largest spec change between original and 1000 variants — much larger in player impact than the max-win cap change (21,100× → 25,000×).
Visual cues for bomb spotting
Some practical guidance for first-time players:
| Bomb value range | Visual cue |
|---|---|
| 2× to 10× | Small soft chime, subtle orb glow |
| 12× to 50× | Medium chime, brighter orb |
| 100× to 200× | Distinct cymbal hit, screen shake |
| 500× to 1000× | Full orchestral hit, screen flash, slight UI delay before the value displays |
The 1000× bomb has a noticeably different animation — the game pauses briefly while showing the value, almost like the engine is announcing it. If you see this, take a screenshot.
Quick FAQ
Can multiple bombs land in a single spin? Yes — observed up to 4 bombs in a single base-game tumble chain. In free spins, multi-bomb landings are more common.
Does the bomb value influence the multiplier or just add to it? Pure addition. A 100× bomb adds 100× to the running total. There's no multiplicative interaction between bombs.
Do bombs award their multiplier even if I don't win? Base game: no — they need a winning tumble. Free spins: they stick around but don't pay until a winning tumble lands.
Are bombs the same in demo as real money? Yes — same RNG, same distribution.
Can the casino reduce bomb frequency? Only by switching to a reduced RTP build. The default 96.53% build has the documented bomb frequency.
Is the 1000× bomb in Ante Bet mode the same? Yes — same value, slightly higher frequency due to overall feature uplift, but specifically the 1000× value distribution is unchanged.
