Maxing PF multiplier then video mode all day is a valid strategy but slow. Video mode is easy to memorize. Jump at the end for an extra 1M.
Every time you launch a ball (even after a lock) you can select your doctor to help you. Choose wisely.
Maxing the PF multiplier (upper ramp loops) is very important. After 10 loops, complete W-H-O for Sonic Booms (10M x multiplier each shot).
Every wave of video mode completed gives a doctor. All 7 doctors gives a bonus of 20M (which can be multiplied).
Choosing doctor: #1 helps you get to video mode. #3 helps you get extra ball. #6 increases multiplier faster. #7 helps you get to Multiball.
At the end of game, each doctor is worth 1M points, duplicates included!) This is multiplied by playfield multiplier (up to 4M per-doctor)
Completing the last wave of video mode is the sum of all of the previous waves, for a max of 110M on the first wave.
Extra balls are surprisingly valuable on Dr Who in competitive play, because you get a free doctor to play with.
Doctor #2 doubles the hang-on score up to a max of 4M, which goes to 16M with 4x playfield.
Doctor #4 is surprisingly effective during Multiball, as he makes REPAIR targets worth more, and balls constantly rebound into them in MB.
Doctor #3 increases the timeout for spelling W-H-O
It's possible to memorize the first wave of video mode, but subsequent waves are randomly generated.
W-H-O loops give up to 12M per letter and 16M Hang-On Bonus. They can also be restarted, and will advance progress towards extra balls.
When starting multiball hit an outside Dalek to begin—its a slightly lower jp value at first, but you'll get one more before reaching davros
If you have access to operator settings, set Video Mode to Extra Hard, makes game more fun, not all that much harder, but gives more to do.
After locking 2 balls and the Time Expander rises, select Dr. 7 to help you start Multiball faster. He doubles your white target hits.
When starting multiball, hit the center Dalek target to start with the higher jackpot value and also get closer to super jackpot (Davros)
