At some arcades, you may see the game where the light bulbs spin around and around the machine. You push the button stop it and receive the number of tickets the number lands on. Seems simple enough. There are also designated 'jackpot' areas where if you can stop it on there, you win the jackpot. Here's what I do to guarantee a jackpot almost every time.

Because of the color burn from when looking through your iPhone or whatever mobile device you use, I can see the light more vividly. Then, after a try or two, I can usually hit the jackpot. Easy enough if I press it on Jackpot and it turns out it was 2 or 3 after, I try to land 2 or 3 before. Simple logic, there.

Good luck!
