Sims city Minimizing the tab

Getting a high outdoor Room score is about fixing the negatives and adding positives.

Things that lower your outdoor Room score:

• Garbage. Throw it away.
• Animal (or human!) excrement. Clean it up.
• Newspapers or magazines other than the current issue of each. Old ones get a grayish color. Throw them away.
• Dead flowers. Replant them or just remove them.

After that, you need to improve the looks of your outdoors:

• Plant trees or flowers. If you use flowers, keep them watered.
• Put in other room-improvement items such as statues.
• The sure-fire way: Get a swimming pool. A pool can guarantee the highest possible Room score. The score for a pool depends on the size. If you don't get highest room score with your pool, try making it a bit larger. There's a point when the Room score is maxed out by pool alone. It doesn't take a very large pool; you don't have to make it cover half the lot or anything.

Also according to IGN, you can evict a family from their home and move them back in. When you do so, the Mystery Man will come to your house and drop a Magico starter kit which contains 35 Magicoins. You can save the coins and do this as often as you like.

You can also go to Magic Town with a Sim with maximum logic and perform on stage all day long. The maximum output from this method for a day appears to be 675 Magicoins.

As a side note, a Sim can only carry 32,767 Magicoins at once, and MagiCo's Bookshelf of Dimensional Storage will only hold 30,000. (Source)
