1+9=10

Another simple arithmetic card game/activity for young children, also called "Räknespel"/"Counting game" in the rules. The deck consists of cards numbered 1-9 and players draw from it in turn. Whenever a player has cards adding up to 10, they can bank those cards for one point a card. Cards left in hand when the deck has run out count for minus one point per card. The rules suggest playing several rounds with cumulative scores.
