Spark of Genius

Play'n GO sets Spark of Genius in the early days of electricity, where two rival inventors chase a contract to power a fictional Parisian grid. Maynard Woodrow and Tess Jacova each bring their own technology to a sparking centrepiece dominated by circuit-covered tiles, and the presentation leans into a steampunk, retro-futuristic mood rather than a strictly historical one.

The reels form a 6x6 grid without conventional paylines. Instead, matching circuit symbols must link into a closed loop, and a minimum of four connected tiles is required for a payout. Closed circuits of four pay 0.3x the stake, scaling up to 300x for a loop of 25 or more. Winning tiles clear from the grid and new circuit symbols tumble in to fill the space, with cascades continuing until no further loop forms.

Two meters run alongside the reels, one tied to each inventor. Woodrow's Manifest Energy and Jacova's Resonant Energy both fill from winning circuits and hold up to 35 charges across three thresholds. On the Manifest side, 15 circuits trigger Relay, stripping 7 to 11 circuit symbols from the grid at random; 25 circuits trigger Overload, which drops 2 to 6 destroy symbols that clear neighbouring tiles; and at 35 circuits, the Empire Energy Spin free game begins. That round places a 2x2 Transformer symbol worth a starting x3 multiplier in the centre of the grid, acting as four connected circuit tiles. Linking a closed circuit to it raises the multiplier by 1, up to a ceiling of x20, and the boosted figure applies to every win for the rest of the feature.

Resonant Energy runs in parallel on the other side of the board. Fifteen circuits activate Gyrota, rotating 3 to 7 circuit symbols to reshuffle potential connections, and 25 circuits bring in Dynamo, adding 2 to 6 special four-point circuit symbols. At 35 charges, the Free Energy Spin awards a single free spin whose multiplier climbs through x1, x4, x8, x12, x16 and x20 as further wins land, applying across the whole round. Non-winning cascades during either bonus keep the supporting mechanics ticking over rather than stalling the feature.

At the numbers: volatility runs at the maximum 10 out of 10 for Play'n GO, paired with a 10,000x max win ceiling and a default 96.3% RTP configurable down to 84.3% by operators. Spins are priced between 0.10 and 100, and Spark of Genius reached casinos on 15 May 2024.
