How to Play

Draw a card from the deck and place it into any column you choose. Keep an eye on the score above each column — once you hit 21, the column is cleared and you earn points. But be careful: if the total goes over 21, you lose! Plan your moves, challenge your friends, and see who can score the highest!

Tips for Beginners

  • Scan all available moves before choosing the first obvious one.
  • Plan one or two turns ahead when the game gives you time to think.
  • Use simple, consistent strategy first; risky plays make more sense once you know the rules.
