Schrum-Schrum[1] or Alte Jungfer ("Old Maid"[a])[2][3] is a simple, domino-like, card game from Germany which is suitable for children.
[1] Schrum-Schrum may be played with a Piquet or Skat pack of 32 cards ranking, from highest to lowest: King, Queen, Jack, Ten, Nine Eight, Seven, Ace.
The next player in clockwise order either builds a Seven of any suit onto the Ace if he has one or, if not, starts his reserve pile.
Cards are built on the Ace in ascending sequence to the King, their suit being irrelevant.
After shuffling and cutting the dealer distributes all the cards, it being irrelevant if some players have an extra one.
