Expansion

Expansion is the ability of players to add more land to their park. When your park expands, the newly annexed land is filled with obstacles that have to be cleared before the land is useable.

Each expansion costs more coins than the last. After two expansions, a mystic map is also a requirement for expanding.

Mystic maps can be requested from neighbors each day. Neighbors can accept your request to give you a mystic map at no personal cost. However, you are limited to one mystic map request per neighbor daily. Since the number of mystic maps required for expansions increases gradually, you will benefit from having more neighbors.

Update as of June 12, 2012: Team Lava seems to have increased expansion coin costs by roughly five-fold (it is not exactly five-fold for some costs, so we will need individual expansion data). These new costs are denoted in parentheses for now. Once it looks likely that Team Lava will settle on the new prices for a while, the old prices can just be replaced.

Update as of June 26, 2012: It has been two weeks since the change, so it appears that the new prices are to stay. The old prices have been removed. Slots with unconfirmed new prices have a ? next to them, representing that the numbers are guesses (old values multiplied by 5). However, confirmed values show that very low and very high expansion numbers have costs that are do not correspond to the multiply-by-5 pattern. Thus, every price tagged with a ? must be confirmed individually.
