Two days ago, I bought "Cash Spin" for the iPhone. The price is $1.99. While playing that game, I've scored the "Major Jackpot" 5 times. Here is the template of that wheel, its a 30 wedge figure.
"Free Games" - Land on that wedge and you get 12 free spins on the slot machine. You also get to double the winnings.
"Minor Jackpot" starts at $100.00 and increase $0.01 for every second.
"Major Jackpot" starts at $5,000.00 and increase $0.01 for every second.
Not only you get to play the app, it also shows you the location in which the machine is available.
