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.
Color of minerals
In Orapamine, there are 4 types of minerals (red, blue, yellow, transparent) and petroleum (black). The elastic wave fired is white, but upon colliding with minerals of color, the color of the elasticwave changes. It can mix colors as it collides with multiple minerals.
a. If the elastic wave collides with a red and blue mineral, it will come out violet.
b. If it collides with a red and yellow mineral, it will come out orange
c. If it collides with a blue and yellow mineral, it will come out green.
d. If it collides with red, blue, and yellow minerals, it will come out black.
e. A white mineral reflects the elastic wave without changing its color upon collision.
f. Black reflects the elastic wave and does not change its path.
The elastic wave does not bounce off but rather dissipates upon hitting it.
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
