Ways to (legally) earn credits:
1. Mini games.
Jungle Cruise2. Non-player characters:
In Jungle Cruise if you deliberately damage your craft and run out of fuel, you still get 20 credits. So you can do this as fast as your computer (and your sanity!) will allow
The new Pirates almost requires that you play with other people. Playing against the computer awards so few credits as to not be worth the time
In Haunted Mansion with a reasonably fast computer and Internet connection, it should be possible to get 200-300 credits per game. Plus, every 10-25 times your team "wins", there are bonus credits awarded
Fireworks can be a double edged sword. You have to make it to at least a certain level (3?) before getting any points (150?). However, if you are very good (which requires not only skill but also a fast computer and good internet connection) you can rack up some big points. Get 240,000 but not win, and you get 1,000 point bonus, plus 375 for reaching level 5.
Esmerelda (Emporium)3. Main Street Music
Shrunken Ned (Shrunken Ned's Shop)
Blackheart (Pirate Treehouse)
Ghosts x 3 (Haunted Mansion)
Each of these award 20 credits. You can visit these once every 12 hours, so you can collect between 160 and 320 credits per day.
Mix a songIf you're a night owl, one of the best times to collect NPC credits and Main Street Music credits is in the last 10 minutes before closing. Since you can't start any mini-games in the last 10 minutes, it's probably the most productive use of the time.
Play a song
Mixing a song awards 25 credits once per day. Playing a song awards 25 credits and can be repeated hourly. The time is based on clock, not elapsed time, so you can play a song at 5 minutes before the hour and 5 minutes after the hour and pick up 25 credits for each.
4. Host games
Some host games award credits for prizes, but it's hardly worth it. The queues are generally so long for the host games that you'd be far better off playing mini-games or collecting NPC credits. VMK staff may have realized this - I don't see as many host games awarding credits anymore.Looking through the above it seems like it should be fairly easy to earn about 1,000 credits per day in less than an hour online. That's 210 for NPC and Main Street Music (about 10 minute), plus three or four games of Haunted Mansion or Pirates (about 10 minutes each, or 30-40 minutes). Do this every day for a month and you'll have 30,000 credit or more.
