If you want a fun, mind-blowing effect to carry with you everywhere, look no further!

Four cards are displayed face up. One of the cards is freely selected by a spectator. The chosen ace is revealed to be "odd" because it's the only card with a RED back! ALL of the other backs are BLUE-backed!

Next, a different card is selected, and this card now becomes the "odd" card, because it's the only card with a BLUE back and all of the other backs are now RED!

The first "odd" card has a red back, while the second "odd" card has a blue back.

Now for the finale! The remaining two aces are turned over to show their backs are now YELLOW and GREEN!

In the end, each card's back is a 100% different color, adding to the mystery and visual impact.

Best of all, everything can be FULLY EXAMINED, and the routine resets instantly.
