The cards in the detective game are placed on top of each other so that their back sides can be seen. then, printed shapes consisting of 9 pieces are placed in the middle where everyone can reach. the bell is placed in the middle where everyone can reach. the cards are turned over starting from the top card in sequence. the first person to see the shapes on the game card on the ground presses the bell and shows the shapes. you need to be careful. because all my pictures have a few different variations. the shape you first see may not be correct. for example, you may encounter the cat picture you see both with and without a tail. if there are three shapes on the card, 3 points are added, if there are 2 shapes, 2 points are added, if there is 1 shape, 1 point is added. if the bell is pressed incorrectly, the game continues. no negative points are given to the person who presses the bell incorrectly. the person who collects the most points wins the game.
