Make mine a mocha in this coffee shop simulation game.
Arctic Arcade have released their latest game to Google Play: "You are given a certain amount of cash boost to start up your own Coffee Shop. You then proceed to buy Coffee machines and other upgrades for the shop. While you progress through the game, you will get better prices, speedier service, automated work force to help you keep on top of the demand, and many other options."
This is a nice relaxing idle game, with a simplistic approach.
