The terrorist Boris has placed a bomb in the city! As a member of the bomb squad, it is your job to disarm the bomb before it explodes. You start the game with a view of the code number display which is damaged. In order to find the code which disarms the bomb, you have to repair the various circuits in order to fix the display. By selecting a square on the code number display, you will be brought to the corresponding circuit which you can repair using your cutters, pliers, and soldering iron. Your partner, Frank, will guide you through the repairs by telling you what needs to be done, in what order repairs should be performed, and by helping you position the tools. Depending on the circuit, you may need to cut out parts or replace parts (spare parts are located at the top of the screen). If you use an incorrect replacement part, or perform the repairs in the wrong order, you will lose time or even cause the bomb to explode. On the more difficult skill levels, circuit parts may even overheat and cause a fire; luckily you also have a fire extinguisher with you to deal with this situation! When enough circuits have been repaired that you can decipher the code, enter it into the computer and the bomb will be disarmed (an incorrect guess will cause it to explode, however). You may choose to have a one, two, or three digit code to guess and several difficulty levels are available.
