You are a waiter and you must deliver your drink to the customer. Play on your Blackberry Playbook held like a tray, and make sure you don't spill the drink. Watch the reflections in the top of the drink to assess your progress. All spillages reduce your tip, and if you smash the glass you'll incur more disdain and even lower tips.
Get your drink there fast and get it there perfectly! Up to four players. Create your own courses, from four times around the dining room table, to twice around the garden or all the way around the neighbourhood. High Score table, and highly competitive!
