The Adventure Game - Season 4

First of six programmes
A direct broadcast from Arg - a small red planet on the far side of the galaxy, inhabited by a race of friendly, trans-metamorphic dragons who have the ability to assume the shape of their visitors.
Each week three explorers from Earth travel to the planet in search of the Great Crystal. However, on arrival they find that their quest is hampered by a series of logic problems, set by the planet's ruler, His Royal Highness, The Rangdo of Arg.
This week's Earth visitors Sheelagh Gilbey, Ian McNaught-Davis & Roy Kane

An amusing game of logic and ingenuity broadcast from Arg, on the far side of the galaxy.
His Highness, the Rangdo of Arg, delights in testing the perspicacity of any visitors who arrive on the planet in search of the Great Crystal.
Will his problems baffle this week's trio, or will they enter the Black Mine?
The explorers this week are Johnny Ball, Barbara Lott and Liz Hobbs

The third of six direct broadcasts from Arg, a small red planet on the far side of the galaxy, inhabited by polite dragons. A team of three explorers from Earth are about to arrive on Arg, searching for the Great Crystal which has been hidden by the planet's ruler, a rather grumpy teapot.
Tackling the problems this week with logic, amusement and dexterity, are Fiona Kennedy Ian McCaskill and David Sandeman

His Highness the Rangdo of Arg has arranged a particularly tricky set of problems for this week's explorers. How many Argonds are lurking round the pond, and how are the explorers expected to get through the Crystal Mine when the anti-gravity boots are chained up?
Tackling these and other puzzles this week are Ruth Madoc, Professor Heinz Wolff and Deborah Leigh Hall

As this week's team of Earth explorers arrive on Arg, His Highness the Rangdo has just finished setting a series of problems to thwart them in their quest for the Great Crystal. Will they complete their task before being evaporated, or will they have to settle for a green cheese roll as compensation?
Travelling to Arg this week Joanna Monro, George Layton and Val Prince

The final broadcast direct from the Planet Arg. Another team of Earth explorers have problems to solve. Will any of them win a cheese roll and survive long enough to cross the Vortex?
This week's explorers are: Heather Couper, Keith Chegwin, & Adam Gilbey
