Double Bonus is another game that will return over 100% with proper play. The table in the link below shows what happens to your positive EV (expected value) when you play machines that have less than full pay schedules. The orange boxes highlight the pays that casinos often modify to make the game win more for them.

Another game that is sometimes seen with positive return to the player is Super Aces. Again, you must find a machine with the full-pay schedule for this to be true.
