An imaginative way to learn 60 specialist words associated with medieval castles and to find out where they belong in the castle. Aimed at the 11 to 15 age range, it would also be useful to adults. Accompanying the cassette is a list with 60 words and their meanings, and 9 x 13 outline grid, on which you can make a plan of the castle as you move around, naming each square and looking for three pieces of a gold goblet.

In order to proceed you're asked a question relevant to that part of the castle, and a correct answer allows you to proceed on your quest. A wrong answer brings a ringing tone and a guard appearing to hit you into the moat, before you restart - which can be awkward if you are deep into the castle. Small numbers appear at screen top right to let you know your position on the grid.

All spellings must be correct, and up to four variations are given for each question asked. But be careful to collect disguise, keys and light as soon as possible.
