Cyber Runner Slot by Peter & Sons

Infection is the oddball here. It fires randomly, swapping every low-pay symbol on the grid to a high-pay in one shot. No trigger conditions, no scatter requirements - it just happens mid-spin, sometimes mid-cascade, and suddenly a board full of hazard signs and vials turns into a wall of cyberpunk android faces worth 8x the payout. In free spins, where the progressive multiplier is already climbing, one well-timed Infection can revalue the entire grid while that counter sits at x12 or x15.

That multiplier is the backbone. Each cascade win adds +1, standard tumble logic, but in the base game it resets after every cascade sequence ends. Free spins change the rule - the multiplier persists for the full session, never dropping back. Seven spins is the starting award from three scatters, scaling up to thirteen from six. No retrigger once you're inside, though. Extra scatters landing during cascades before the round starts add +2 spins each, so the trigger spin itself matters. Expanding wilds show up on reels 2 through 6, filling their entire column when they land, which feeds longer cascade chains and pushes that multiplier higher before a single payline even resolves.

Neon-drenched from edge to edge. The grid sits inside a monitor frame wrapped in black cables and mechanical claws, backed by a rain-soaked city street glowing pink and electric blue. Cyborg portrait symbols have LED-lit eyes in green and gold, and even the low symbols - syringes, biohazard triangles, pistols - carry enough grit to fit the setting. Golden Bet bumps the stake by 50% and increases both expanding wild frequency and scatter odds. Buying in costs 120x for a random free spins count between 7 and 13, no way to pick the exact number.
