The TAC shopping game features several travel agents, with the goal of assembling travel packages. Each agent is acting on behalf of eight clients who express their preferences for various aspects of the trip. The objective of the travel agent is to maximize the total satisfaction of its clients (the sum of the client utilities).

At the end of the game, the travel agent holds several plane tickets, hotel rooms and event tickets. If it ends the game holding negative balances of any entertainment tickets (because it sold tickets it did not have), it is assessed a penalty of 200 for each ticket owed.
