A spectator chooses a playing card, then selects one of three symbol pieces (sun, moon, or star) and marks their chosen card. They then give the second symbol piece to you, the performer, and keep the third for themselves.

Then you summarize: "You have chosen a card and marked it with a symbol piece of your choice, then you have chosen another piece for me and one for yourself. You have made four decisions, and I have not influenced you in any way. On the contrary: If you want, you can now swap any symbol piece with another!"

Once your spectator has finally made up his mind, the prediction that has been on the table the whole time is read out, and four matches emerge:

The chosen card is predicted, as is the symbol of the marker stone and the respective symbols in the hands of both participants!
