I'm in! WPT is my favorite game (and I also own, among others, a CV, LOTR, WOZ). Why? It has a great combo of an open playfield with great flow, tons of drop targets, a challenging mini-pf, very deep rules with cool modes, and probably the best rule integration of any pin made to date. (Keefer himself has indicated that WPT is one of his best efforts.)
Some set-up tips for those who haven't seen them yet: remove the top left orbit gate (2 screws), and turn off the flop/turn posts in the settings to improve flow. (These are recommended by SR himself.) You can also turn off the flipper hint where the right mini-pf flipper flips to let you know the ball is coming there--it gets annoying after a while!
Strategy tips? Here's a bunch, in no particular order:
Lock the ball in the Ace in the Hole cage on the mini-pf, and then AVOID hitting the captured ball to start this mb. Why? This is the easiest mb to stack with another, because mb balls will launch to the upper pf with a ballsave. Too many people try to start this mb right away.
The 3x shot is critical. You get a 3x shot added every time you complete a drop target (draw poker) hand. If you have at least one 3x, then one (and only one) of the inlanes will light up. Rolling over the lit inlane (from the playfield or the ramp return) will give you triple scoring for about 5 seconds--basically one shot. So, it is best to AVOID rolling over the 3x light (by hitting a flipper button to switch the light to the opposite inlane) UNLESS you have a high-scoring shot. Examples of good 3x shots include a river shot to either ramp (just one card left on the 7-card holdem hand on the pf display), which will score the hand value multiplied by the pot value, or a single drop target to make a good draw poker hand. A good hand or draw to a good one (like 3-of-a-kind, straight, flush, etc.) is even better for the 3x. If you just have just 6 unrelated cards or a single pair, you may want to save the 3x for a better hand/draw. Also use the 3x if completing the hand will finish a city/tournament (values start at 1M, so triple this is good!). Remember, always keep an eye out for the inlane light and avoid it unless you have a single high-scoring shot available with that flipper. You can set up a 3x shot by getting a ramp return to the inlane.
Upper playfield: Always go for the far left opening to light the random award light on the pf below it, if it's not lit. A backhand from a ball trapped on the left mini-flipper is usually good. Lock the AitH ball and then avoid it until you start a different mb as noted above, then stack. Otherwise, hit the white standups and go for the hurryup (opening to the lower pf) when it flashes. If you have a double hurryup, a few quick target hits before scoring the hurryup can get a lot of points. Hurryups are the main scoring on the mini-pf.
Main pot value has a starting value based on difficulty setting, and increases from spinner (orbit) shots. If you have a good holdem hand (or draw to one), build up the pot before hitting the river. But if you drain, the main pot goes back to its starting value on the next ball. If you have 5-6 cards and nothing good in the hand, it's best to just finish the hand and hopefully get a better next one. BUT, if you build up enough points (depends on difficulty setting) in the main pot with spinner shots, you start an All-in multiball, which also finishes the holdem hand. (You can use a 3x with this orbit shot if you're almost at the main pot value needed to start it--value is shown in the status screens.)
Note that you can make it to the mini-pf WITHOUT increasing the holdem hand by hitting the left backwall opening just to the right of the left ramp. Or, you can get up there and increase the holdem hand progress by the right ramp. Which one you choose depends on your hand status, main pot value, etc. For example, if you're at the river with a good hand, you can set up a lucrative 3x shot by hitting the LEFT backwall shot to the upper pf and letting the ball drain to the right inlane, making sure the right inlane is lit, then hitting the left ramp right away to score 3x the holdem value (plus city value, if it's the final city hand). Hitting the right ramp to get to the mini-pf and feed the right inlane would finish the holdem hand without the 3x, which you don't want to do here!
Side pot value is increased with each pop bumper hit, and resets after each ball. You can increase how much each pop adds to the side pot by hitting all 4 standups above the pops (below the mini-pf). You can move the lit targets with the flippers (like a regular lane changer) to get them faster. Side pots are scored with each orbit shot made during a few multiballs; values can be built to 500k or more.
Poker school modes (6 round inserts by the slingshots) are started by the elongated trough just to the left of the right ramp, when lit. 2 of them are drop target modes, one is 'spot the tell' mode where you get a big score (starts at 1M) for making one of the 6 main shots corresponding (left to right) of the character on the DMD making an odd motion or sound. Change Gears mode gives more points when making shots to the upper pf and then lower pf. Stacking this mode with a mb gives HUGE points. You usually have to finish a holdem hand before the poker school trough re-lights to start another mode.
Starting all 6 poker school modes and then hitting the lit trough again starts a Wizard mb. I think jackpots in this mb are bigger if you finish/defeat more of the individual modes--not sure of scoring off the top of my head!
Then there are some other minor scoring features, like victory laps after completing certain modes, card tricks by making some main shots, etc. I'm not sure of the scoring details.
Finishing all 6 cities brings you to the big WPT championship tourney--that's a LOT of ramp shots! And then there's the Keefer Invitational--you can see what you need to get there in the status screens. Basically start every mode/mb, get a certain number of points (generally 25M) in each of several modes/mb's, etc. It's a valinor-type achievement.
Feel free to add scoring details, corrections, additions that I may have missed!
