Spell your number, moving your poker chip ( ) over one card for each letter as you do so.

Example: If SEVEN is chosen, you spell S-E-V-E-N and end up on the Ace of Clubs.

If you end up on a face-up card, turn all face-up cards face-down.

If you end up on a face-down card, turn all face-down cards face-up.

Congratulations! As the name of the trick suggested, you chose the only red card.
