Mario Party 9 Bosses and minigames: earn points without feeding rivals

Separate cooperative boss damage from competitive scoring.

Edition covered

Original Wii edition. Everyone shares a vehicle; character choice does not supply a unique Dice Block.

Bosses reward individual performance

Four players face a large Whomp during a boss minigame.

Everyone attacks one boss, but the score table ranks the players. Surviving without scoring may leave you behind.

Free Play isolates the troublesome event

Practice a minigame directly before another board attempt. It is faster than waiting for the same event to reappear.

Boss Rush follows Solo completion

After finishing Solo Mode, purchase Boss Rush for 500 Party Points in the Museum to play boss sets.
