You are a detective hunting down a bank robber on the run and trying to recover the money he stole. At the start of the game, the computer displays a forest surrounded by a hedge. The robber has just entered the forest from the West (left-hand side). As he blunders about among the trees, he leaves a trail of footprints and scattered banknotes. After a while, the robber may drop the bag of money in the hope of throwing you off his trail.
You will have to wait a few seconds while the computer gives the robber a ten-move start. Then begin tracking him by keying in the direction (N, E, S, W) you want to go, followed by a number for the distance you wish to move. After each move, any clues you find about the robber’s trail will be shown on the screen:
N, S etc = footprints going North, South etc
X = confused footprints going in several directions
£ = scattered banknotes
+ = shows that the robber no longer has the money
* = the stolen money
R = the robber
If the robber reaches the East (right) side of the hedge, he may escape from the woods and get away.
The game continues until both the robber (R) and the money (*) have been found. The object is to find both of them in as few moves as possible.
