I got a very nice Jumping Gems stick, but, as we all know, the gem selection is awkward & rather unbelievable. A friend suggested forcing the needed selection with a forcing die, and TF Dice seeemed right.

What you get:
—one translucent blue die without spots;
—sheet of sticky spots to place on the blank die;
—the gimmick that makes the force work.

What you have to supply:
—a parallel-sided transparent glass;
—a black mat

Problems:
—When you are told that this forcing die setup will work with any die, you realize that this a a $5 trick masquerading as a $25 trick;
—The gimmick is fragile & becomes more fragile after preparation; but you do receive plenty of gimmicks, so there’s that;
—Since a parallel-sided clear glass is needed to shake the die, and a black mat is needed to help conceal the gimmick, the trick arrives incomplete;
—The video instructions do not show the trick being performed in the wild. I’m unsure if this force die setup has ever been used in a live performance;
—The gimmick requires tape on the glass, so you don’t end clean.

Conclusion:
Will this rather fragile & laborious die force work? Yes. But so will a cross cut force, and the cards won’t break, and they’ll leave you clean.

Not recommended.
