Mario Tennis Aces comes with a neat bonus if you purchase it at Best Buy. Those who pre-ordered the game may have received a set of exclusive red tennis balls, which also display the Mario Tennis Aces and Best Buy logos. This incentive may still be available at your local Best Buy, so be sure to ask about it out before it’s too late. Mario Tennis Aces was released yesterday, June 22, for Nintendo Switch. In addition to supporting local and online multiplayer options, the game features an Adventure mode with a variety of missions and boss battles.
