About sevens and 777 slots
The lucky seven is the oldest top symbol on slot machines, and games with 7, 777 or sevens in the name usually keep a retro, fruit-machine style. They tend to have few features, which makes their numbers easy to compare.
Fewer features do not guarantee a calm game. Read the volatility and max win of each title below.
