This 2009 sports title merges the Mario and Sonic universes to simulate the 2010 Vancouver Winter Olympics. As a main game for the Wii, the core gameplay involves competing in 27 official motion-controlled events like skiing and ice hockey, with optional Balance Board support. Uniquely, it features "Dream Events" that offer enhanced, non-traditional winter sports challenges. Players can compete individually or progress through a 17-day Festival Mode.
The game transports players to the atmosphere of the Vancouver Winter Olympics of 2010. Players step into the shoes of beloved characters as they compete across a range of snow and ice-based sports, capturing the spirit of international winter competition.
The gameplay is structured around 27 official Olympic events, each translated into motion-controlled mini-games. These events cover a broad spectrum of winter athletics, including disciplines such as skiing, snowboarding, bobsleigh, ice hockey, and figure skating. Success in these events relies heavily on precise timing and execution of the required Wii Remote motions.
For players seeking an alternative input method, certain events offer optional support for the Balance Board peripheral, adding another layer of physical interaction to the competition.
Beyond the standard Olympic events, the game features a series of unique "Dream Events." These specialized challenges take the established characters and settings and introduce enhanced features and visuals, allowing for more imaginative and exaggerated athletic contests that go beyond the strict rules of the real-world Olympics.
Players can engage with the events individually, or they can experience the competition within a structured "Festival Mode." This mode spans a simulated 17-day period, allowing players to progress through a series of competitions over time.
As a main release title, this game does not feature any downloadable content (DLCs) or expansions, meaning all available events and modes are included in the initial package.
The primary structure for competitive play is the Festival Mode, which simulates the duration of the Winter Games over 17 in-game days, providing a continuous path through the available athletic challenges.

A mobile game made to promote Mario & Sonic at the Olympic Winter Games. This mobile port only features the playable characters from the Sonic the Hedgehog series. The game was released on iOS devices, and later removed because of the poor quality.

The DS-exclusive adventure mode features a story in which Dr. Eggman and Bowser melt away all the ice needed for the Olympic Games. To set things right Mario & Sonic need to travel to different locations, talk to the inhabitants and solve challenges. Those consist of the sports mini games with certain winning requirements. Playing this mode also unlocks the dream events. Besides this players can decide to enter the party game mode or to play the games separately respectively in a custom tournament. All modes except the adventure mode are also available for up to four players.
