Each series was structured as a tournament whose grand prize was a holiday to any destination the winner desired.
The contestants started the round by choosing four free squares each to turn to their respective colours.
Next, each in turn chose one square; if a picture was hidden there, the host asked a question related to it.
However, a miss sent them into a dead end, from which they could return and pass the junction only by answering another question correctly.
If the contestant made it past the final junction before time ran out, they exited the maze and were asked a bonus question worth 10 points.
