A device used for playing [i][[Duel Monster]][/i] card games in the  [[Yu-Gi-Oh!]] manga and anime. Typically takes the shape of a forearm-mounted contraption with foldable blades that is used to place cards on it. The device utilizes "Solid Vision" technology to generate [[hologram]] of monsters and cards played by both players.

In [[real life]], the device was conceived by [[Takahashi Kazuki]] as a way to give characters an ability move more freely during a card game match for dramatic effect instead of having them [[duel (yu-gi-oh!)|duelling]] on a table.
