Expansion Gem Question

[LalaSmooth]

Okay something is really bothering me, I have expanded my restaurant using 40 gems (as saving coins for halloween quests next week) my next two expansions are at 40 gems each but then at 20x23 and so on it goes up to 80 gems!

[mattyboo1]

70 gems becasue they are the newer expansions and are big extensions

[mattyboo1]

Correction 80 gems

[jamesdean1957]

It goes up every time you expand

U can use coins and neighbours for expansion.
Coins are easy to earn.

Yeah next one is at 2.500.000
