I didn't find this game very "winnable" since there was way too much stuff going on and not enough winning combinations. Just kept spending $$ and no profit in sight. What makes it worse is because of the nature of a video slot, you press the button, it spins, things pop up, and it's time to spin again, all in about 5 seconds. I wasn't a big fan.

Monster Mansion™

MonsterTM Bonus
