The basic idea of the prop is from an unknown Czech magician. Included with the prop are three video presentations and tutorials, which you can perform as mental or winning game effects. The basis of the effects is to predict the winning symbol and / or the number chosen by the spectators and the routine builds on itself to a logical and bewildering conclusion. The winning symbol is the symbol which will be above the spectator's freely chosen number after rotating the disc as many steps as the chosen number, in the direction indicated by the arrows on the disc. As a first phase you can predict the spectator's winning symbol without seeing the disc. The second performance is about predicting not only the spectator's winning symbol but his chosen number as well. Finally in the third presentation you can predict two spectators' numbers and winning symbols. Super easy to master and perform! The prop is examinable, there are no hidden gimmicks! The item is made of premium high quality jobban hangzik plastic material, instead of cardboard. A different outcome each time!
