Kwyjibo is a modern classic. It’s a pop up trick that has a stringent rule set to perform the trick “right”. If you can master this trick you’ll be ready for level 2.
Start with a Trapeze. Pop the yoyo up and cross your hands, throw hand on top and hitting the vertical string. The yoyo will land on the outside string.
Rotate your hands so that you are now cross armed with your non throw hand on top.
Pop the yoyo up again, uncross your hands with your non throw hand index finger hitting the vertical string. When the yoyo comes down it should land on the outside string for a Double or Nothing.
Slightly pop the yoyo up once more, drop the Double or Nothing and pull apart to land the yoyo back to a Trapeze. Bind return and your finished.
