In this game there are 5 bombs hidden in a 8x8 grid. The goal of the game is to find and locate all these hidden bombs before time runs out. To find out the location of these bombs, you can send probes into the grid by clicking on the boxes outside of the grid one at a time and observe its path traveled to guess the location of the bombs. Probe always travels in a straight line and when if comes into a direct contact with a bomb it will be stopped; this is known as a "Hit." If a probe comes next to a bomb it will be deflected 90 degrees to the right if it is on the right-hand side of the bomb; or it will be deflected 90 degrees to the left if it is on the left-hand side of the bomb. A probe that got deflected and comes out on the other side is known as a "Detour." Finally, a probe may also come back out of where it enters this is known as "Reflect." As you marked each of these probes entrance and exit, you can make accurate guesses as to where does each of these bombs locate on the grid. You can mark the location of each of these bombs in the grid by clicking directly on the appropriate location once you selected the bomb icon on the right. Once ready, click on the "Try Guess" button to confirm the bomb locations to defuse. Keep in mind that incorrect guess will excite the bomb and decrease the time on the timer. If you run out of time, you loss the game.
