Eri.cards

Both adults and children can play in Eri. But the game is not as simple as it seems at first glance. Place cards on the playing field, making lines from them. Extend them and cross the lines between each other. The more colored figures will be in the line, the more points you will get for it. But remember that the figures on the cards in the line should not be repeated.
