The object of the game is to get 777 as quickly as possible.
You spin the reels one at a time. Tap a reel to start it, tap it again to stop it.
There is a World Leaderboard that you can post your best time to.
The timer starts when you tap a reel and stops when you get 777. If the time is your best time, a dialog pops up from where you can post your time to the World Leaderboard.
You can reset the game at any time.
This isn't a gambling game, you don't win anything, other than enormous pride for getting on the World Leaderboard!
