Scourge of Rome

Play'n GO traces Hannibal Barca's historic route against Rome across Scourge of Rome's intro map, moving from Spain over the Alps and down into Italy before the reels themselves open on snow-covered peaks rather than the desert-and-columns look most Roman slots default to. The base grid is a fixed six reels by four rows, generating 4,096 ways to win, and stakes run from 0.10 to 100 a spin. Volatility carries an 8 out of 10 rating, and the top return among five available RTP settings reaches 96.2%.

Eleven symbols pay in the base game. Five card ranks, ten through ace, form the lower tier and pay 1x to 1.4x the stake for five matching icons on a line. Above them sit a set of weapon and equipment symbols - an amphora, a ring - plus two armoured warrior figures and an elephant, with the highest of these paying between 4x and 20x for six matching symbols.

Two wild types work the base game: a standard Hannibal wild that can only land on the four middle reels, and a rarer Hannibal & Sirius wild that fills an entire reel by itself. Getting two or more of the standard wild onto a single spin sets off the Wild Flip, in which every wild connected to a winning combination gets a coin-flip chance of upgrading into the full-reel version. Once free spins start, neither wild type is in play.

Scatters decide the free spins award: three, four, five or six of them trigger or retrigger ten, fifteen, twenty or twenty-five spins, and the round can climb as high as a hundred and fifteen spins in total through retriggers. The reel structure itself keeps changing during the feature - a random selection of symbols along the bottom rows locks in place at the start of each spin, drops out of the grid once that spin resolves, and shrinks the playing area in the process, while a brand new row is stacked on top between spins to build the reels back up again. Elephant symbols become sticky for the whole round, paying regardless of gaps between them and without any requirement to begin on the far-left reel. A Warhorn symbol can also turn up during free spins; each time it does, every visible elephant shifts up by one row before the lower symbols freeze away, and if the grid is holding fewer than three elephants when that happens, the Warhorn tops the count back up to three.

Scourge of Rome's maximum win runs to 40,000 times the stake, in keeping with a highly volatile design built around that shifting free spins grid.
