What is Pokémon Ga-Olé...?

"Pokémon Ga-Olé" is a kids' amusement game machine where you can enjoy super intense Pokémon battles on a huge 50 inch monitor! Enjoy Pokémon battles featuring direction filled with intensity and realism!

Summon more and more powerful Pokémon with your very own strength!
"Pokémon Ga-Olé" is a game where you enjoy 2-vs-2 Pokémon battles while cheering on your on-hand Pokémon by pressing buttons according to onscreen prompts!
After battles, your on-hand Pokémon's "roar" increases, which lets you continue battling against the Pokémon that heard the roar and appeared before you! The louder your "roar", the greater the chance of powerful Pokémon apparing, like legendary Pokémon, here represented with "Houou"!



If you brilliantly manage to catch the opposing Pokémon after a white-hot battle that makes your hands sweat, your own Pokémon's "roar" will increase, and a strong Pokémon will appear! Insert a new coin and continue battling!

The "Special "I Choose You Cap Pikachu" Ga-Olé Disk"'s unique design!!


The "Special "I Choose You Cap Pikachu" Ga-Olé Disk" we're giving out is a Ga-Olé Disk you can't otain through normal play! Not only that, but if you use this disk to play "Pokémon Ga-Olé", the special mode "Houou Roulette" exclusive to this disk will activate, allowing Pikachu and Houou to attack in succession!
