i absolutely love this game, five stars hands down. I have been playing it for years. So with that being said, it's been an amazing game until very recently. I was playing, and starting to collect my money from the shops, but now there's no indication above the shops showing you can finally collect the product/money once it has accumulated in full. I assuming it may have been a glitch or error dealing with the last update. I would greatly appreciate any feedback that remedy this conundrum

Having a blast! I like how easy it is to build up cities on my islands. I've been playing for less than a month, and one island is already complete. I frequently earn gold by watching videos, though I hate the pop up ads that get in my way as I'm about to do something, which is why it's only 4 stars. Also, prices for everything go up once you start buying property to develop. Would be nice to buy multiple items of same thing at once and have level 10 businesses profits be on auto collect.

Good simcity style build game. You don't need to pay to play. Just play!You can watch ads to gain extra prizes for completing tasks or to get free gold. Daily prizes, which can be doubled if you watch an ad and daily tasks which can be helpful except when gold is involved, example: spend 100 gold to get 50 gold or spend 500 gold to get 250 gold ect. Some of the builds can take days to complete, which I don't care for, but it's a decent enough game that you don't have to play 24/7.
