Roman Bonanza (Hacksaw Gaming) – Review & Demo Play

Slot review: Roman Bonanza

Roman Bonanza by Backseat Gaming drops me into a sun-drenched Roman city and gets straight to the point. It’s a scatter-pays slot on a 6x5 grid, where 8+ matches anywhere trigger tumbles. Bets run from 0.10 to 100, with high volatility and a 96.31% RTP. All wins collect in the Tumble Win meter, then symbols clear for fresh drops. The setup aims at punchy hits and multipliers rather than a slow grind, and it carries a max win of 10,000x.

Slot overview: Roman Bonanza

Roman Bonanza’s pay-anywhere setup uses two symbol groups. Low-pays are green, orange, red, blue, and purple gems. Clusters of 8–9 pay light amounts, while 19+ can reach 50x the bet on these stones. Everything tallies through scatter wins rather than lines, so wide spreads matter more than neat stacks. I like how the grid opens up after each tumble, as fresh drops can extend a cluster and push it into the higher brackets where the numbers start to look meaningful.

High-pays carry the Roman kit: boots, ring, chalice, and helmet. Land 19+ and you’re looking at 200x to 400x the bet, with mid clusters stepping through fair mids. There are no wilds at all, which fits the design, as Catapult and Bonus symbols do the heavy lifting. Catapults link to multiplier action, while scatters handle free spins. The maths leans on clusters plus tumbles, so symbol values feel balanced once multipliers start stacking from highlighted positions.

Slot features: Roman Bonanza

After any win, those positions light up. If a Catapult symbol is present on that spin, it fires once tumbles stop and turns highlights into Multiplier Bombs. Bombs then resolve top to bottom, left to right, feeding a total multiplier. Additive bombs come in three tiers: x2–x5, x10–x25, and x50–x100. Golden Multiplier Bombs are multiplicative and apply x2–x10 to the running total. When the dust settles, that total multiplier hits the Tumble Win, which is where big ladders tend to form.

Free spins come in two flavours. Arm the Catapults triggers with 4 scatters for 10 spins, and Catapults show up more often. Land 3 scatters during the round to add +5 spins. Siege Command is the premium mode from 5 scatters. You get 10 spins, a higher Catapult rate, and highlighted positions stay for the whole feature. That persistence can blanket the board over time, so one Catapult late in the round can turn a modest run into something far more lively.

If you prefer shortcuts, the menu offers four routes. BonusHunt FeatureSpins cost 3x and make a bonus five times more likely. Centurion FeatureSpins are 50x and guarantee at least one Catapult per spin. Or buy the rounds outright: 100x for Arm the Catapults, 250x for Siege Command. I tend to sample BonusHunt when testing a seed, then switch to Siege once I see the grid framing up well, as sticky highlights pair nicely with a single timely Catapult.

Our verdict: Roman Bonanza

Roman Bonanza looks sharp, plays fast, and leans into high-risk, high-reward play. The Catapult system adds proper suspense to tumbles, and Siege Command’s persistent frames are where I’ve seen the engine breathe. The flip side is a base game that can feel dry between big hits, plus feature costs that bite if variance plays rough. I still rate it for the 10,000x ceiling, the clean scatter-pays flow, and the way multipliers can snowball when the board lights up.
