Roman Empire Slot by Habanero

The Caesar coin in the top right is the symbol the whole game pivots around. It carries the legend "Doubles The Prize" right next to the jackpot meters, and the rules-text reading isn't decorative. The pf telemetry shows each Caesar coin landing on a winning payline multiplies that specific line's prize by 2x, and the evaluation is per-line, not per-spin. A single spin can resolve with three winning lines where two carry a 2x boost and the third pays flat, because only the lines the coin physically touches get doubled. It's a quieter version of the multiplier-symbol pattern Habanero leaned harder on later in titles like Witches Tome, with no escalation and no collect meter, just a direct prize doubler that lives in the symbol pool alongside the standard premiums.

Free games run on a 3+ scatter trigger that pays anywhere on the grid, the prompt visible above the reels reading "3 Or More Anywhere Triggers Feature." The bonus retains the Caesar coin in the symbol pool, so the doubling mechanic carries straight into the round. There's no buy menu and no Super Bet shortcut here. Roman Empire shipped in April 2016, predating both of those Habanero standards by several years, so the only path into the bonus is landing scatters on a paid spin. A Gamble feature sits on the base game for double-or-nothing card guesses after any line hit, which is the older Habanero convention before they phased gamble menus out of newer titles.

Twin random progressive jackpots ride above the reels, Grand and Minor, both drawing from the older traditional dual-pool architecture rather than the Jackpot Race network the studio rolled out later. Either can drop on any paid spin with no symbol requirement, the Grand seeded at 5,000 and the Minor at 50 in the demo's EUR display. The art leans into imperial pageantry without pushing it: the reel cabinet sits inside the arched stone arcade of a Roman amphitheatre lit in dusk blue, the Roman Empire wordmark up top is engraved in classical Trajan-style serifs flanked by golden eagles, and the symbol pool runs from a bronze gladius-and-shield through a centurion's plumed helmet to a purple-robed Egyptian-styled noblewoman as one of the top-pays. Card royals get the unusual treatment of being filled in with what looks like mosaic-gem inlay rather than printed pips, which fits the marble-and-gold colour bias of everything else on screen.
