Trouble Brewing is a Problem Solving game released in 01/04/2014 [April Fools day]. The idea of the game is brewing orders of coffee and serving them when they are full. If the cups overflow, they will have to be tossed.
There are two sizes of cups/orders: single and double. A good way to get your speed up is to devote one room to singles and one room to doubles (when you get to levels that have more than one room).
