Dynamic Games For The ZX Spectrum by Tim Hartnell is typical of many books of this kind. Whether it will appeal to you depends on how many games you already have in your collection and your opinion of the twenty here. On comparison, they stand up well. Tim Hartnell is undoubtedly the foremost Sinclair author, and he has compiled a good variety of programs in this book. The games subdivide into four categories: arcade games, board games, adventure/simulation games and 'improve your mind' games - though I'm afraid none of them are very original.

Each program is supported by introductory text, which details the highlights and programming techniques employed. Learning this way can be both fun and profitable. There are some great games, but games such as 'Checkers', '3D Drive' and 'Death Race 2000' are more typical, although well suited in their degree of complexity to ths type of learning. Books of this nature are useful programming aids, but at a price of £5.95 there may well be others that serve the same purpose more economically.
