Arc Lord

Lightning bolts and a five-by-five grid of tumbling symbols carry the Greek-mythology theme in Arc Lord, built by Hacksaw Gaming partner studio Backseat Gaming around Zeus and his thunderstorms. Columned architecture in cool blues and greys frames the reels, and while the overall look leans clean and cartoonish rather than striking, the wild reel animations give the presentation some life. Winning symbols clear from the grid on every hit and new ones drop down to refill the gaps, with the sequence repeating for as long as fresh combinations keep appearing.

Card values from 10 through A form the low end of the paytable, followed by a book, a ring, an hourglass and a crown as the premium symbols; five matching royals pay 1x to 1.5x the stake, while five premiums pay 3x to 10x. A Zeus symbol doubles as the trigger for the game's central mechanic and, once activated, also functions as a wild — landing it spawns between one and five wild reels across the grid, with only one unactivated Zeus symbol able to appear at a time, and five wilds completing a win independently pay 50x the bet.

A global multiplier tracks alongside the tumbles, starting at 1x and climbing by one full step with every winning cascade; it applies to all wins in play but resets at the start of each new base-game spin. Landing three scatters opens the Thunderstrike bonus game, awarding 10 free spins and restarting the multiplier at 1x, though here it carries over between tumbles rather than resetting until the round finishes. Four scatters instead trigger Lord of Lightning, a longer 15-spin round that starts the multiplier at 5x under the same carry-over rules. Both bonus games offer a Wheel of Fortune gamble on entry, letting a player risk the round up to three times for extra spins or a bigger starting multiplier, or bank what has already been won — a failed gamble forfeits the free spins entirely.

Feature buy options sit alongside the bonus games: a cheaper spend at 2x the bet makes a bonus round three times more likely to land over a run of spins, a 50x buy guarantees a Zeus symbol will appear, and the Thunderstrike and Lord of Lightning rounds can also be purchased outright for 100x and 250x the stake respectively. Across 19 paylines, Arc Lord runs high volatility with a 36.6% hit frequency and a maximum win of 25,000x, and RTP is set at 96.26% by default with an alternate 94.25% configuration also available.
