The price of the Medium Island is a quite high for fresh players: 50,000 coins or 25 Island cash and you can only purchase it, of course, if you’ve already bought the previous upgrade (the Small Island, if I remember correctly). However, for experienced treasure diggers, I am sure that this Island is quite a blessing since they’ll finally have where to place all their items.
What about you? Have you purchased the Medium Island expansion in Treasure Isle?
