For every player there are different buttons to add points within a round:
+1 point +13 points for the one with the player with the Queen of Spades +Remainder, to assign the remaining points to a player Shot the Moon-Button, to add 26 points for all other players in this round
Additionally there is a readjust button to subtract points, if one has made a mistake while adding points.
When all points are properly distributed, you can finish the round, so that the points of the round are added to the total points of the game.
As soon as a player has reached the 100 points in a round, the winner will be determined.
