The 4 bubbles

They play 2 players or 2 teams (parents can team with their children and help them in the tables that do not dominate too much). We have to get together 4 cards of the same color (4 in line) and prevent our opponent from doing it before us, all based on multiplying 2 numbers on the bottom of the board (from 1 to 9). The game has regulations in Catalan and Spanish.
