Songbirds

User summary
ことりファイト! (Birdie Fight) is card game about birds trying to achieve dominance in the forest. Each bird is a different colour in the game.

Players are forest spirits, trying to secretly guide their chosen bird to success. The cards are numbered 1 to 7 in red, blue, green and white. The players lay a card from their hand to a 5x5 grid after nut tokens (points) are laid out for each row and column.

When the grid is full of cards, the rows and columns are checked. The colour with the highest total in a line takes the nut token for that bird. Colours with tied totals are ignored, so a low value card can win the nut token for that bird.

When the nuts are totalled up for the birds, the players reveal their final hand card. That card is the bird they favoured (so more than one player might be helping the same bird), and for each player, the number on the card is added to the nut total to identify who has the dominant bird.

Since the players choose which bird they favour by leaving it as their final hand card, they can delay this choice until they see how the game is panning out.

The game rules come in Japanese and English, the game itself being language free. The game includes rules for 2-4 players or a solitaire/co-op mode for 1-2 players.
