Deca Sports Extreme consists of ten games, as it is customary for the Deca Sports series, and they are:
- ice hockey
- snowball fight
- snowmobile raving
- sumo wrestling
The game is in 3D, but 2D gaming is also allowed and recommended for the younger than seven years. Multiplayer can be played by up to four players either by local wireless or incorporating the 3DS download play option. All game modes and options from the preceding titles are there once more; new are the power-ups and unlockable items to customize playing characters as well as teams.
