Thunder Knuckles

Thunder Knuckles puts a blue boxing robot in the ring, crackling with lightning and wearing oversized red gloves. The symbols are electrical gear: the Golden Glove, Tesla Coil, Power Switch and Lightning Bulb, plus five kinds of battery cell. Power Dials, Spark Plugs and BONUS scatters drive the features, and a Charge Meter tracks how far the robot has powered up.

The game is played on a 6x5 board and pays anywhere: 8 or more matching symbols win wherever they land. Winning symbols are removed and new ones tumble in until no new win forms. Power Dials can land on any spin or tumble. At the end of the spin their values are added together and the total multiplies the spin's win. Three or more BONUS scatters start 10 free spins. In free spins, Spark Plugs charge the meter, which raises the lowest value a dial can show.

Thunder Knuckles is coming soon to Stake. Its RTP, max win and every bet mode will be added from the game's published math when it is released.
