Merry Flipmas

From BoardGameGeek:

Merry Flipmas (And a Happy Zoo Year!) is a light, puzzly hand manipulation game. Each card has two carolers on it, one on the front and one on the back. You can only play the side facing you, and you cannot rearrange your hand. On your turn, you can choose any adjacent group of cards and flip them, giving you the carolers on the back, but also reversing the order of the cards. Each carol requires a different arrangement of singers, and if you get your carolers in order, you can sing it. Players draw and discard cards to match the patterns of the carol cards on the table. The game ends when a player has collected the winning number of carols, which changes based on player count. Can you be the first choir to sing all of your carols? -description from the publisher
