ARENA Game System: ARENA is a multi-user, Web-based system for organizing and conducting tournaments. ARENA is game independent in the sense that organizers can adapt a new game to the ARENA game interface, upload it to the ARENA server, and immediately announce and conduct tournaments with players and spectators located anywhere on the Internet. Organizers can also define new tournament styles, describing how players are mapped to a set of matches and how to compute an overall ranking of players by adding up their victories and losses (hence, figuring out who won the tournament). To recoup their operational costs, organizers can also invite potential sponsors to display advertisement banners during games.

Activity Diagram

Create an activity diagram for the scenario described below: A new user registers with the Arena system as an organizer and then uploads a new Connect4 game. Next the organizer announces and organizes a tournament with players. The organizer also solicits advertisers and accepts applications received. Accepted advertisers are then allowed to place their banners during the game. When a tournament ends the organizers announces the results. Make sure to use split and synchronize constructs of activity diagram and organize activities into suitable lanes.
