That is a really nice idea. The response would be twice as good :)

@@FuntimeMagic There's all sorts of extra effects you can use with this. I also use Tenyo Flash Dice, so you can make the spectators selected number coincide with the six identical numbers appearing from the flash dice. I have the Hanson Chien Sonic Dice gimmick which looks much nicer, so I prefer using that. And when you combine everything, you then have the forced playing card plus the flash dice for a killer mentalism effect.

I think the die isn’t really a cube. If each side has a slightly different length, you can feel it from the outside. To decide if it’s odd or even maybe there is a small piece in the middle because only the odd numbers have a hole there.

Yes it is a guess

See through bottom

@@davidgerrard9964 No he cannot see through the bottom. very easy trick

Yes, that's correct. Each of the sides, aka the 3 axis, (x, y and z) has a different height. And depending on how high the lid is raised, it tells you which of these three axis the dice is orientated. And there is a small dimple inside the middle of the top lid. So depending on whether it's an odd or even number, the lid will jiggler around or lie flat. So then you know the combination of which of the three axis plus whether its odd or even, which gives you the number of the dice. I combine this with six playing cards (1-6) to enhance the mentalism effect. So after determining what the number is you then force the identical playing card.
