The game is nice with the rebuilding part and even the solitaire game is fun. After a few times I was ready to give it 4 or 5 stars but then I realised you kinda gamble your coins to play and if you lose, you lose coins. Right now I can't play unless I wait for a "payment" every hour, and I need at least 2 to play once. A game that doesn't let me play is a big no for me.
