Essentially Part 2. Bosses are covered in the Tutorial as well, but I wanted to put them separately, since they deal with Adventure mode and not necessarily Score Attack (or anything else, for that matter).

During bosses, there are no power pellets, and you only have a certain amount of time to clear each maze. Once enough dots are eaten, a fruit spawns, and the Giant Ghost in the background will attack the maze and anger the ghosts -- they will attempt to trap you. (That's what bombs are for; use them wisely.)

Your goal is to eat each fruit (optionally, collect the required amount of lives in specific categories) and eat the Super Pellet to defeat the boss. If the timer runs out, you have to start from the beginning. On most bosses, you need 20 lives to get all the stars possible, so aim for that. It should be relatively easy, since you start with about 5 or 6 lives, and 2 spawn after every Giant Ghost attack.

Adventure Mode:

Green: Time Attack course. You have a certain amount of time to clear out each maze and move on to the next. Bombs are provided, so use them when a fruit/Power Pellet appears. Eating a ghost will not deduct from your time, so use that to your advantage when hunting them down. Every 1st and 2nd level is early-mid game, and every 4th and 5th level is a late-game maze, where you'll have to chase down Power Pellets. Applicable in Areas 1-5.

Orange: Similar to Time Attack, except there are no power pellets, and you have to chase fruits instead. They appear every 3rd level in Areas 1-5, and every 3rd and 7th level in Area 6.

Purple: Score Attack. Your task is to earn 5,000,000 points in one go. Some courses require you to complete them in about 6 minutes on Pro difficulty, so don't be afraid to bomb mid-game to get to some of those later mazes. Area 6.

"Phases": (Usually I refer to certain parts of mazes as phases, because of how some of them are laid out.)

Phase 1: Several mazes with 1 sleeping ghost at forks in the road before going to a maze with clusters of 3 and a Power Pellet. Two or three of these.

Phase 2: Chase power pellets, and eat nearly all dots in the maze before going to the next. Every maze after Phase 1, twice or three times repeated before cycling back.
