なないろのおと (Nanairo no Oto)

In Prismatic Note, players move around seven piles of colorful musical notes, trying to be the first to collect all seven colors. A player's turn consists of moving to a new space, and using a "spell" card to activate one or more piles, giving the players on those piles a card. Duplicate colors cancel each other out. The game ends when one player has exactly seven colors.
