Find the location of diamonds in the Orapa mine

Choose one person to be the presenter of the problem. The presenter will be the director of the Orapamine, and the other players will become mineral prospectors. The player who correctly identifies the positions of the minerals (Tangram coins) placed by the director wins the game.

On the solution sheet, there is a grid of 10 x 8 squares. Choose one of the numbers (1-18) or letters (A-R) along the outer edge of the grid to fire an elastic wave.

The elastic wave travels horizontally or vertically from the firing position, bouncing off each mineral at right angles or horizontally and vertically until it exits the mine.
The director must answer where the elastic wave comes out and what color. Upon hearing the response, explorers record it on their solution sheet.

The player who correctly identifies the positions and colors of all minerals first wins. Players can guess the answer even when it's not their turn.
