How to play with stones?

Rules of the game to catch stones: (1) Leave three stones (or small sandbags made of cloth) on the table; (2) Pick up one of the stones and throw it upward; (3) Before the stone thrown upward falls on the table, grab the second stone on the table and catch the stone thrown upward just now. And so on, grab the third stone. (4) If you grab three stones at the same time and then throw them up at the same time, the palm will turn over quickly, so that the three stones will fall on the back of your hand; Then throw it away. If you can catch three stones, the game will be successful. (5) If the thrown stone is not caught, or the stone on the table is not caught, the game is over and the opponent begins.
