Each of the various playfield zone features relates to one of the individual Doctors as listed below, and also affects gameplay rules. Completing a Doctor's playfield zone does not award that Doctor, but earning that Doctor will make earning the zone's award easier. The individual zones are as follows: Doctor 1: Lower right-hand orange target bank, labeled "E-S-C-A-P-E" - When all six of these targets are lit, the player can shoot the upper left orbit (toward the jet bumpers) to enable video mode. Each successfully completed video mode wave awards the currently lit Doctor, and alters the game's ruleset as described above. Once Doctor 1 is awarded, each hit in this area counts double. Doctor 2: Left entrance lane above the upper left flipper. Hang On mode is enabled when the right inlane switch is tripped; a flashing red arrow lights up next to the upper left flipper when it is active. If the left entrance lane is hit before time runs out, the Hang On award doubles. Doctor 3: Right ramp, left entrance lane, and upper right loop, in that order. Accomplishing this sequence of shots lights "W-H-O", which can award extra balls after a specific number of completions of the pattern. Using the factory settings, the first extra ball is enabled after 2 W-H-O sequences are completed. When enabled, an inlane or outlane (which can be changed by using the flippers) lights, tripping the lane switch awards an extra ball. Doctor 4: Upper left target bank, labeled "R-E-P-A-I-R." Completing all six targets before time runs out enables Unlimited Millions, which causes each successive hit on the target bank to award an ever-increasing number of points. As long as the target bank continues to be hit before time runs out, the award will continue to increase and grow upon itself. Doctor 5: The Transmat is enabled after scoring 1,000,000 points on the jet bumpers. If Doctor 5 is already awarded, the jet bumpers will score double their normal value, building the Transmat's charge faster. Once the Transmat is fully charged, the player can hit the target just underneath the upper right loop to Transmat the currently selected Doctor. The rule changes pertaining to that Doctor then remain in effect for the rest of the game. Doctor 6: Upper right loop. Successive loops enable a full-playfield multiplier of up to 4X. Without Doctor 6 scored, and using default settings, the
