Transferring symbols, free spins, multiplier wilds, and win multipliers are the key to propelling you to great wins that may just include the unbelievable 50,000x top award per bet line.
In the Sparky 7 slot machine, RTG takes you on a trip back in time via the traditional approach of a classic slot-themed on lucky 7s. The symbol combination is as simple as they come, with red 7s being the highest-paying symbol, followed by blue, red, and green 7s. Single, double, and triple BARs symbols are the other dominant icons, and there is also a Wild depicted by ‘W’ and a Bonus symbol.
