If you are able to play the 4th card of the same value, you move forward 12 points! If your opponent has another matching card, they’ll earn 6 points.
That way, players can see the last amount that you scored. Whenever you score points, take the peg of your color that’s furthest back and move it ahead of the one that’s in front.
Watch what cards your opponent plays and pay attention to the count to get extra “pegging” points.
