Tutankham is an arcade action game played from a top-down point of view. You are an explorer in King Tut's tomb on a mission to retrieve as many treasures as you can find. In addition to the treasures, you will also find a key in each chamber. This key is needed to unlock the entrance to the next, more difficult chamber. Be careful, for the tomb is guarded by many dangerous creatures! Cobras, bats, scorpions, and more appear in the maze and will cause you to lose a life if you're caught! To defend yourself, you are armed with a laser gun which can be fired left or right, but not up or down. In each chamber, you are also given one "flash" which can be used to destroy all creatures currently on the screen.
The gameplay involves navigating through increasingly difficult levels of the tomb, collecting treasures and keys while avoiding deadly creatures. You must use your laser gun wisely to fend off the enemies, making the most of your limited number of flashes. With each successful completion of a level, you'll unlock new areas of the tomb, presenting fresh challenges and opportunities for treasure hunting.
