Rivet Riot

Rivet Riot is a steampunk-themed slot with a 7×5 grid, cluster pays mechanics, an RTP of 96.7%, high volatility and a maximum win of 50,000x.

Winning clusters form from symbols connected horizontally and vertically. When a cluster wins, those symbols clear, the remaining symbols fall and the grid re-evaluates for additional wins. Each winning cell touched advances Cell Charge, and winning cells double their value after payout up to a cap of x4,096.

Power Rams clear active paying symbols within a single column, with a limit of one Ram per column per cascade step. Ram 1, 2 and 3 each apply increasing charge boosts, while Ram 4 converts five cells in that column to Overclock.

Parts Magnets select one active paying-symbol type and advance charge whenever matching symbol copies are touched. When all matching symbols are cleared, the Magnet removes itself. Crusher Cores advance charge beneath all active paying symbols in the grid, then remove those symbols and clear themselves. Arc Torches advance charge in neighbouring cells, remove active paying symbols in adjacent positions and preserve other tools and badges.

Scrap Vault triggers from three Vault Badges and uses three Fuel across its steps, with one consumed per step. Loose scrap values and tools refill Fuel, and the feature pays a capped total of remaining value at its end.

Overdrive grants ten free spins with persistent Cell Charge that carries across every spin and cascade. Landing four or more Vault Badges during Overdrive adds ten additional spins. The feature ends when spins reach zero or the 50,000x maximum win is hit.

Black Label grants ten free spins with persistent Cell Charge and fires seven opening Power Rams from left to right. These opening Rams multiply columns or convert cells to Overclock. Three or more Black Labels trigger ten additional future spins, though Vault Badges do not retrigger the opening Rams.

Charged Board is a paid entry option with 35 independent charge states, including an Overclock charge state option. Badges triggered on the Charged Board cannot activate Scrap Vault, Overdrive or Black Label, and the feature ends after a single grid spin.

Relay Roulette uses a physical selector instead of board entry and lands on no-feature, Overdrive or Black Label, with the no-feature result paying x0.
