This is the best game ever. I play it for 1 hour daily. The way prices of items increase exponentially I have estimated it will take 5000 Euros (200K gold coins assuming 40 coins per euro) to unlock respectable 80 to 90 % of islands and buildings. If you dont want to spend, playing 1 hour a day will need 15 to 20 years to achieve the same. If speed and rewards are doubled, say, through vip membership, still it will take 5 to 10 years to make same progress which is probably more than phone life

I do enjoy this game, I also play number 6 as well. My only issue, and the only reason for me not to give it 5 stars, is the fact that despite there being an option for ads to get double rewards and to speed up builds, there are apparently none ever available. It's very frustrating. Not that I want to watch ads, per say, but having the option there but unavailable for no given reason is almost enough to make me not want to play

perfect. I used to play this when I was younger and it's so nostalgic now. I'm so glad to see that it hasn't changed a bit and it's still the same as I remember. The only problem is that I have absolutely no idea how to make gold coins without having to purchase them with actual cash. I also hate that the buildings require you to buy them with those damn gold coins after one purchase with money. It's super annoying but either way, the game is peak👌👌
