Frosty Rumble is a VS 4 mini-game in Sonic Shuffle. It is randomly played when a player lands on an Event Space.
This mini-game has the players running around in an icy arena with ice blocks everywhere. Players must pick up a block and throw it to break it, releasing Rings (and sometimes a Forcejewel) from inside. Larger blocks take longer to lift but have more Rings inside. When carrying an ice block, a player may choose to throw the ice block at another player, making them lose their Rings. It's easier to move a character when they are not carrying a block.
There is a bonus of 20 Rings for whoever gets the most Rings in the mini-game, with a bonus of 10 for second and 5 for third.
|Pick up the ice and throw it at the other players! Rings and Forcejewels will appear from the broken ice.
— Game Rules
|Large blocks of ice contain more rings, but they're heavier, so it'll take you longer to pick 'em up and throw 'em.
