Eastside Hockey Manager is a sports simulation game, which allows the player to take control of an ice hockey team from over 30 playable leagues. Currently the game does not have any official licenses within the game (with the exception of the British-based Elite Ice Hockey League), as a result fictional league, team and player names are used instead. Once the user has selected a team to manage, they are able to make changes to their roster, via trading, drafting or signing new players. From there they can scout new players, set their preferred tactics, and play against other teams. When the user is playing against another team, they can watch the game via a top down 2D match engine.
As a result of the fictional nature of the game, several fans and unaffiliated websites have created 3rd party data packs that add real leagues, teams and players into the game, for example, the league featured in the game as 'National League' becomes the National Hockey League.
