Jackpot Opportunity is a single-player event match in Super Smash Bros. for Wii U. The player controls Villager and must collect 1000 coins in a coin battle against 3 other Villagers, each with different custom moves. Unlike a normal coin battle, being KO'd is an automatic failure. Assist Trophies that appear in the match will only summon Isabelle.
This event is unlocked by clearing Oh Yeah, Luigi Time!. Completing the event unlocks the right path.
Completing the event on normal or hard difficulty within 100 seconds awards a Countdown Lloid equipment.
