All right I guess some Examples of Minigames.
4 v 4: Avalanche Aware
Avoid a incoming Avalanche while Sking down the mountain. Control yourself with the Pad. Shake the Remote to jump. Avoid Snowman, Houses, and Trees.
1 v 3: Robot Havoc
The single player is in a Large Robot trying to get the 3 Players who are avoiding it for 30 Seconds. The Robot can try to squish players and can shoot a Laser by pressing 1 Button. Press 2 for a light Beam stunning players. The 3 Players just move around and jump with 2 button.
2 v 2: Wrecking Time
The teams might try to Destroy a Worn down house. 1st team to do this wins. Use the Pad to move the Wrecking Ball and Shake it to swing it. Try all of the house including the outside stuff. Try not to hit each other or you'll be stunned.
Battle: Slippery Match
The players battle on Ice. It's slippery so be careful. Use the Pad to move, 2 Punch, 1 Jump, 1 then 2 to Kick. As time goes by, the Ice breaks. Sometimes Penquins will get in the way. Last person standing wins 1st.
Duel: Smashdown
An army of Goombas are coming. Control a Thwomp to destory them. Move the Wii Remote Up to command the Thwomp to rise. Swing it fast to make it drop. Crush as many Goombas as you can in 45 Seconds. Afterwards the person who crushes the most wins.
Etc: Mario Puzzle Tetris
Like the Mario Puzzles but now Tetris Style. Make lines of Same Color to clear. Get many Points as you can before it fills up. Press the 2 button to change the position of the Piece. Use the Down Pad to drop it. Left and Right moves it that direction.
Good?
