OK. The first thing to do is to change the multiball setting for the WOF multiball that gets lit by hitting the green targets. On default, hitting ANY green target will give you credit for an unlit green target that you still need. That places too much emphasis on the WOF multiball. Use the next hardest setting which forces you to have to hit each specific unlit green target once to light that specific target. This will make the effort to get to WOF multiball more balanced with Trip multiball and with spelling BONUS. Note that it will get even harder to start WOF multiball a second time (have to hit each green target twice - once to get it flashing, second time to get it lit solid).
First rule of play: Practice that skill shot - can be a big payoff if you make the skill shot and follow it up with a quick shot to the puzzle hole to score the hurry up. Hard to do, but payoff increases each time you do this in a game.
Second rule of play: Get those under ramp in-line targets every time. First target awards the free spin and this is essential to longer ball times and this should be your focus on each ball until you get that target down. Second target lights the center drains to spin the wheel and this can be big points or even an extra ball, so nice to have these lights and nice to get something besides the regular bonus at drain. Third target lights the wild card shot and I believe you can stack wild cards, so hitting the target down is fine even if the wild card is currently lit.
Third Rule of Play: always go for spelling BONUS and then starting the BONUS mode. it's only five shots plus the puzzle hole shot to do this and much lower risk shots than going for the contestants. In general, these modes can be pretty lucrative. Learn the Bonus modes and how to score big in each one (for example, use the bumpers to get the wheel really flying fast in SPIN THE WHEEL). These modes can be loads of fun and with big payoffs, but some are tricky to figure out how to maximize points.
Fourth: try to light the WOF multiball and a BONUS mode so that you can start both simultaneously. I don't believe you can do the same with TRIP multiball when it is lit at the same time as a BONUS mode. I dont' think it starts them both, I believe it just starts trip Multiball. Maybe this varies by settings? Things get really crazy when you get both multiballs at once as you need to keep track of the TRIP multiball shots you need to get to Super Jackpot and also keep track of how many times you've made the WOF multiball shots to take that to Super Jackpot as well.
Fifth: As you get close to solving a puzzle, use the puzzle hole shot to collect vowels. Much lower risk way to light solve the puzzle then the high risk contestant target shots. And a great way to solve to collect the points and awards for the lit contestant without risking hitting the wrong contestant target (collecting vowels keeps the same contestant lit as prior to the shot).
Sixth: Another lesser known trick is the 2X and 3X ramp shot payoffs you can collect. You may have noticed the 2X and 3X decals near the flippers. When you shoot a ramp, the 2X light will come on - this signals that the next shot made will score 2X. If you shoot a ramp and follow it up with a shot to the other ramp - the 3X ramp shot payoff will be lit. So, make sure you monitor the possible awards on the Wheel and at other places at all times. When you see a big amount payoff on a contestant space, for example, lets say 500,000 for a contestant target, consider shooting the ramp shot or shots first and then going for the contestant target after that. You can get 1 or 1.5 million from that one contestant target shot. Also a great strategy during multiballs as the ramp shots lead to 2X or 3X the jackpot payoffs. Yes, it's tough to manage this trick, but most of the tricks in WOF are tough to perform and that's why I like it! And making the ramp shots adds the additional payoff of lighting the extra ball when you make enough ramp shots depending on the setting.
In-Lanes: As mentioned before, the left inlane lights the bumpers for super points. Practice this loop shot into the bumpers from the left flipper as you can extend the length of this bumper payoff by continually hitting the ball back into the bumpers before the mode times out. I've found the right in-lane that lights the left loop just doesn't have near as lucrative a payoff as the left inlane to bumpers shot does.
Wild Card Shot: Practice this shot as well. The awards can often be REAL nice (e.g., solving the puzzle, lighting the trip multiball for all contestants, lighting all the awards for a particular contestant, etc.)
That's probably enough to keep you busy for a long, long time.
