The biggest hit of my Burning Classics run, 115 times the stake, landed in the base game with no Scatter involved. Four rounds of 10 Free Spins still added up to 40% of everything this Booming Games slot paid, and not one of them retriggered.
Technically, Burning Classics is a 20-payline slot with 5 reels, 3 rows. After a win there is a Gamble button, a double-or-nothing round that the rules put at 50/50 and that does not change the game's RTP.
All symbols bar the Scatter can land stacked three symbols tall on the reels. A stack can show on a reel in full or only partly. This can end in some decent wins in the base game. The Wild substitutes for every other symbol except the Scatter.
To trigger it, players need to land at least 3 Scatter symbols. Every one of my triggers came from exactly 3 Scatters. 3, 4 or 5 grants 10 Free Spins. The bet amount is locked while the Free Spins play out. Another 3, 4 or 5 during the span of the bonus adds an extra 10 Free Spins, so the Scatter still matters. None of my rounds retriggered, and they paid between 15x and 114x the stake.
Final Minty Score: Burning Classics is a moderate volatility slot, and I found that the bonus hit 4 times in 290 spins. I finished the session at a 156.9% return, with 90 of the 290 spins paying and 53 of those paying less than the stake. In my view, the base game is a bit samey.
