Speed
Speed is what "Crazy Taxi 3" is all about. Getting the customers you pick up to their destination on time is crucial. To increase your speed, know the city and all its shortcuts. The game provides you with an arrow to help you get to the destination, but it might not be the speediest way there.
Mix It Up
Mix up the customers you get, mixing those with long runs and those with short runs. This will help you earn extra cash and get extra time every time you drop off a customer. Also, avoid picking up too many customers at one time. The max you can hold is four customers at a time, so picking up three to four at once may lead you all over town with no time to get there.
Combos
Use crazy moves to get a lot of combos. This will earn you extra money from the customer. Driving through traffic without hitting anything and drifting through turns will net you extra combo points. Also, you should always use the crazy stop when dropping off a customer. The crazy stop is used by holding the reverse and brake buttons at the same time, making you come to a very quick stop.
Unlockables
"Crazy Taxi 3" has a large amount of unlockable content that can make the game more fun. You can unlock the carriage, stroller and bike by finishing level two of Crazy X Mode. You can unlock all the available drivers in the game by finishing level S-S of Crazy X Mode, and unlock all the maps if you finish level one in Crazy X Mode. If you complete level three of Crazy X Mode, you will unlock Another Day Mode, which will place customers in random places on the map.
