Card Math, Magical Math + More

A dealer deals one card faced up. From there he draws nn cards to a new pile based on the value of the first card(jacks, queens, kings, and aces are 11,12,13,1 respectively)

He continues to make piles using this method until no cards remain. What is the probability that when using this dealing method, the number of cards in the last pile are equal to the card on top of the 2nd to last pile?


I recently learned what Mathematical magic is by watching this video. My challenge for you is to create your own mathematical magic trick.


In my free time I was able to formulate my own 2-player card game. I call the game "Four kings" and the rules are as follow:

  • Both players have hands of 4 cards
  • Players take turns either battling or discarding a card in their hand for a new one
  • To battle, each player lays down their hands then they revile them to create 4 war 'battles'
  • Players takes the cards won through their war battles and discards any extra
  • In the case of a draw, two cards are drawn over the equal valued cards and then battle
  • If a player ends up with less than 4 four cards they draw cards until there's 4 in their hand
  • The game ends when one player has 4 kings in their hand

Here are some problems involving cards

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
