Try the machine next to you if yours is not paying off - According to industry sources, the casinos hardly place two loose machines next to each other. If you are uncertain on whether your machine is loose, it may not hurt to try the machines on either side of you.

Contrary to popular belief, the casinos do not "hide" or move their best machines simply because people find and play them. The casinos want them to be played. When slot machine players see and hear someone hitting a jackpot, it motivates them to pump more money into their own machine in hopes of hitting their own jackpot
