Person A formed 10 small balls of paper (plain white paper, all 10 looked the same). Then person A picked up all 10 paper balls and threw them on a table at the same time. Then you should be able to tell what number between 0, 1, 2, ... and 10 the pattern represents. After everyone gave an answer, person A said the correct number. Then person A picked up all 10 balls of paper again and the next game started.

The table on which the paper balls were thrown was not empty. Everyday things were standing around on the table (bottles, glasses, cutlery, ...). Person A said that everything that is on the table is part of the game and after the 10 small balls of paper have been thrown nothing on the table may be moved. I think that was just for show to mislead the players.
