Overall, there is no strategy that will accurately predict when a slot machine will pay out. That is the whole point of slot machines. They were created to be random, and to not allow people to know when they will hit.
These are the top 10 most popular machines on the floor:
Mega Meltdown - One Dollar.
Tree of Wealth Jade Eternity.
Tree of Wealth Rich Traditions.
Double Ruby.
Friends.
88 Fortunes.
