Mario Party: Island Tour is a party game developed by Nd Cube and published by Nintendo for the Nintendo 3DS. It is the thirteenth overall game in the Mario Party series and the first one for the 3DS. The game features popular characters from the series coming together to play on various board games, with the goal being to beat the other players to the end.
Mario, Luigi, and their friends all receive a note inviting them to Party Islands to come play games. Bowser becomes jealous over not being invited, so he instead throws a party in Bowser's Tower and captures the fun things in the Party Islands with a bubble machine.
