Included is a single-game exhibition mode and a playoff mode (single-elimination or best-of-7), wherein the winner collects a trophy similar to the Stanley Cup.
The game had an NHLPA license but not an NHL license. As a result, the game included all player names and numbers, but not real team names or logos. This is mitigated by the team colors looking exactly like their NHL counterparts, and the teams are all in the same cities as the real NHL teams. The only real exception is that the New York Islanders are called "Long Island."
The Sega Mega Drive/Genesis version also included EEPROM battery saving, which allowed one to save lines and the ongoing Playoff, rather than use passwords as in the Super Nintendo version.
