In fact, the concept of the whole game is nicely done. There are really only two problems, one minor and the other a bit more severe. A phone counter is placed there, and a pizza counter with a matching number to the phone counter is placed on Za central, on time phase 1. Each complete round of play, the first player ages all pizzas one level on Za central. Likewise, each individual player, on their turn, ages any pizzas in their cars.
Tips are cards.
You draw a number of cards equal to the tips you get. Some cards allow you to play them on other players, hindering their progress, while others help you out, mostly by avoiding bad cards that others might play on you. So everyone races around the board, delivering rapidly aging pizzas, trying to get 10 on-time pizzas delivered before anyone else. While there are some lines drawn on it as roads, they have no bearing on play. You are told they are just for decoration.
