Dextram is an arcade shoot 'em up game with a twist. There is no shooting, and you can only turn right. The player controls a ship that is always moving forward, and by pressing a button the ship turns right. The game is a simple score chaser with the goal of getting an as high score as possible. Points are given by getting the enemies to crash, either into each other or into the walls. There are also different power-ups to that can be used to destroy the enemies such as a laser, missiles and a shield.
