The Four Kings Casino and Slots

Millionaire Manor is a slot machine. The bonus round will start when 3 Ghost Detectors land in the frame, regardless of how high your Bet or Lines. This is random and will happen over time, but these 5 need to be in one "sitting" at the machine (people report this pops after only 3 bonus round activations in one sitting). If you or the game lose connection, if you hit to bring up your menu, or if you change your controller's batteries, the sitting is over and you'll have to restart. There's no achievement need to bet any more than necessary on this particular machine, so it may be wise to save your chips for achievements that do require riskier bets.
