Mines of Minos

As the last robot, you must traverse the mine's various levels, gathering spare parts to make more robots (extra lives). You must either avoid the monsters or blow them up with a bomb. After a few seconds, if the monster hasn't hit the bomb, it will explode harmlessly. You can only drop one bomb at a time. If a monster is killed, it will regenerate somewhere in the maze.

To deposit your spare parts, you must get to the center top or bottom of any level. To move to another level, hold your joystick button down while moving through the tunnels on either side. You can also use these tunnels, without holding down the button, to quickly get from left or right side of the maze to avoid monsters.

To win the game, get to level five and ram each of the three stationary monsters to kill them. You will need at least two spare robots as the ramming will destroy you and the monster.

In two-player games, player one is the robot, player two is a monster. If the robot runs into the monster being controlled, the monster is destroyed instead of the robot. However, by pushing the joystick button, player two can switch to another monster, allowing the robot to run into an uncontrolled (and therefore deadly) monster.

The game features difficulty switches: left for the robot and right for the monsters. You can set it to half speed with A or normal speed with B. Game variations include one-player and two-player modes, spare parts needed for a spare robot, mine levels that flood, slowing you down if you enter the water, and more.

Each level has its own unique settings: in some games, dropping bombs is not allowed when the area floods, while in others, it's possible. The game also features invisible mines, which are only visible during explosions by time bomb.

The difficulty of the game depends on several factors, including the player and the level.

Scoring is as follows: destroying a monster earns 20 points, picking up robot parts gives 70 points, depositing robot parts deducts 70 points. Every 1000 points scored raises your power level by one unit until you reach 4000, at which point it caps out.
