Random Number Generator 1-13

Random number generator 1-13 for card ranks

A suit of cards has 13 ranks, from ace to king. The random number generator 1-13 picks one of them with a single spin, so you can practice a card game, run a drill or settle a “high card” call without a deck. It is free, works in a browser, and every rank has the same chance.

If someone just tells you to pick a number between 1 and 13, it does that too.

Map the ranks

Use this mapping so everyone reads the result the same way:

• 1 = ace
• 2 to 10 = the number cards
• 11 = jack
• 12 = queen
• 13 = king

Then spin:

1. Spin with the center button or Ctrl + Enter.
2. Turn the number into a rank using the list above.
3. Choose Spin again for the next card, or Remove it to keep that rank out.

Options that act like a deck

No repeats

A real deck does not give the same card twice in a row. Switch on No repeats and each rank can come up once, which works like dealing one suit. Press “Put drawn numbers back” to reshuffle.

Numbers to skip

Skip 11-13 to drop the face cards, or skip 1 if aces are not in play. The wheel rebuilds with only the ranks you keep.

Mystery wheel

Hide the labels in the Settings tab for a higher or lower game, so nobody can track the pointer during the spin.

Ways to use a random rank

• Higher or lower. Spin a rank, guess whether the next spin will be higher or lower, then spin to check.
• Math facts. Spin a rank and multiply it by a number on the board. Kings are 13.
• High card. Each player spins once and the highest rank deals.
• Card trick practice. Get a random target rank to find in a shuffled deck.

Odds for each rank

Each rank has a 1 in 13 chance, about 7.7 percent. With No repeats on, the chance for the ranks that remain rises as the others leave. The pick is made with your browser’s cryptographic random generator before the wheel turns.
