Gameplay
The game uses a 16-by-18 cell maze which is randomly generated. Initially the T. rex lies in wait. Once the player starts moving, the beast begins hunting. Thereafter, the T. rex may either calm down (if the player goes into a part of the maze that is far enough away), or become more active as the player comes closer. If the T. rex gets a direct view of its prey, the monster will run directly at the player.
The T. rex anxiety level, reported to the player as a statement in the status line, provides an indirect clue to the player's relative distance from the monster. These statements are: REX LIES IN WAIT, followed by HE IS HUNTING FOR YOU, FOOTSTEPS APPROACHING, REX HAS SEEN YOU, and RUN HE IS BESIDE YOU or RUN HE IS BEHIND YOU. The player's speed is greater than the monster's, thus it is possible to escape by running (unless the player is trapped in a dead end). The player can manually map the maze on a piece of paper with each step, but this becomes increasingly difficult as the pace increases. The fast pace can also lead to hard keyboard presses, which, in turn, can shake the computer/16K memory expansion connection, and lead to a sudden reset with several minutes worth reload time.
Points are awarded for each step made by the player any time the dinosaur is on an active hunt. Since the player runs faster than the monster, it is possible to accumulate points by running around in circles with the monster just a few steps behind. Points are also given upon successfully getting away through an exit and into another maze.
When the game ends, the player is informed about being "sentenced to roam the maze forever", and then can either "appeal" or continue playing again in the last maze. If the appeal is attempted, it is rejected with 50% probability, in which case the player is sent back to roam the previous maze again. An appeal which is accepted effectively results in the computer self-reset via BASIC's NEW
statement.
