It looks like an ordinary real die. It rolls like an ordinary real die. But it's no such thing. Whatever number your spectator throws, or chooses, you will know it straight away. You can be blindfold, have your back turned, or be in another room. You can do book tests, divination, fortune telling, cleromancy, or just simple mind reading. It also has a sensitive "which hand" ("Kurotsuke") mode that detects when the cube is moved.  

At 16mm x 16mm x 16mm (5/8 inch) these are the same size as normal gaming dice. They have curved edges and no seams. They are even waterproof. 

The Cube contains a rechargeable lithium polymer battery, but cannot be taken apart. 

.

The Cube comes in two versions - wood and plastic. The wooden versions are made from reclaimed walnut. They give the die a retro feel, and probably reduce the spectators' suspicion that electronics are involved since it seems impossible to enclose so much complicated electronics inside a small block of wood. 

The plastic version looks more like a regular cheap modern die. They are ivory white with black spots.  I have previously made them in red and blue and still have a few of these for sale. Each one is hand-made and finished, in a time-consuming process. 

 

You'll know what number has been thrown because you have a receiver that vibrates with the corresponding number of pulses, like the buzzer on your cellphone. 

 

The receiver measures 75 x 35 x12mm. The easiest place to have it is tucked into your waist band, where the on-off switch is easily accessible.  

The strength of the buzzer pulse is adjustable

The wooden Cube is charged in a charging unit, which you connect with a USB cable  to any USB source (eg a cellphone charger unit or a computer). 

 

The white plastic Cube is charged wirelessly. Just place the Cube onto the charger, and it will start to charge. A red light inside the Cube glows to show that charging is taking place. 

The same units also charge the receiver via a cable

 

The Cube can be charged within about 15 minutes - or quickly topped up in 5 minutes. It will transmit continuously for about two days on a single charge. 

In sleep mode, the Cube consumes very little power

As well as being able to tell you which face is uppermost, an additional feature is motion detect mode. By putting the Cube into this mode, a whole new range of effects becomes possible. As soon as the Cube is moved, even slightly, you receive a signal. This enables you to discover which hand a spectator is holding the Cube in (Kurotsuke) - by holding their wrists and slightly moving them up and down - or to discover which of several spectators is holding the Cube (and which ones are holding a non-gimmicked die). Or to detect when the Cube has been moved.

With no obstructions, the Cube transmits up to 130 feet (40m). If the Cube or the receiver are covered or otherwise obstructed, the range is reduced. If you need a greater range, please get in touch to discuss options
