Battleship on Steroids!

About Orapa Mine, from BoardGameGeek:

Choose one person as the problem presenter. The presenter will be the director of the Orapamine, and the remaining players will become mineral explorers. The player who correctly identifies the positions of the minerals (Tangram pieces) placed by the director wins. Players take turns starting with the player seated to the left of the director, proceeding clockwise. Elastic Wave Shooting On the solution sheet, there is a grid of 10 x 8 cells. Choose one of the numbers (1-18) or letters (A-R) along the outer edge of the grid to shoot an elastic wave. The elastic wave travels horizontally or vertically from the fired 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 exits and in what color. Upon hearing the answer, explorers record it on their solution sheets. The player who first correctly identifies the positions and colors of all minerals wins. Players can guess the answer even when it's not their turn -description from the publisher
