The free spins round is where this slot earns its volatility tier. Everything outside the bonus is a slow burn; everything inside it is where the variance lives.
Triggering Free Spins
Land 4 or more lollipop scatters anywhere on the grid to start the round. The base award is 10 free spins. Triggering with 5 scatters or 6 scatters does not extend the count further on this title — it is a flat 10 spins regardless.
Retrigger
3 or more scatters during free spins award an additional 5 spins. Retriggers can stack, though landing them gets exponentially less likely each time.
Bomb Math During Free Spins
This is the core mechanic that separates 2500 from the original Sweet Bonanza. During the bonus, multiplier orbs (bombs) become an active symbol. Their value range:
- Low tier: 2x, 3x, 4x, 5x, 8x, 10x
- Mid tier: 12x, 15x, 20x, 25x, 50x, 100x
- High tier: 250x, 500x
- Ultra tier: 1,000x, 2,500x
Bombs do not pay on their own. They wait on the grid; if a winning combination resolves, all bomb values currently visible are summed and the total multiplies the payout for that round's wins. The high-tier orbs are deliberately rare. A 2,500x orb landing in a feature where it actually triggers (i.e. a paying combination resolves while it sits on the grid) is the mathematical event the entire slot is built around.
Super Free Spins / Super Scatter
Sweet Bonanza 2500 does not include the "Super Scatter" tier present in Sweet Bonanza Super Scatter. Some players conflate the two — they are different titles. The 2500 variant has a single feature, the standard free spins round, with the new orb table.
Bonus Buy
The Bonus Buy purchases the free spins round at 100x your stake. At 1.00 stake, that is 100.00. The buy delivers the bonus directly with 4 scatters worth of trigger. RTP on the buy is reported by Pragmatic at 96.51%, marginally below the base RTP. That tiny gap is by design: the buy removes the variance of waiting for a natural trigger, so the studio prices the convenience.
One note for jurisdictions: bonus buy is unavailable in the UK, Netherlands, and several other regulated markets. If the buy button is missing from your client, that is regulatory, not a bug. The full feature breakdown sits on the Sweet Bonanza 2500 bonus buy guide.
