Originally published 70 years ago (1938), this book has gone though many revisions and is now into its 22nd edition. Modern versions of the book are difficult to obtain second-hand, but fortunately the latest revision has now arrived, with 96 pages rather than the 52 pages of my parents 1960s edition. It looks like the booklet format has changed rather than any more information added. This 'Penguin' booklet is smaller and spiral bound. I'm not over-impressed with the printed style, there's few illustrations, no colour except very garish red highlights, and there's no index - just the contents chapter headings, e.g. 'Types of Hands p 41 to 67'. So it's difficult to find a specific hand without flicking through, and they aren't listed in any particular order as far as I can see. I'll have to borrow my mum's 1960's version to compare, but either way it seems a missed opportunity to bring Robertson's 'The game of Mah Jong' into the 21st century. But it's all there, paper quality is good, and it looks like the books built to last. Plus one can hardly grumble at the price (I paid a fiver from Amazon). The books 14.5 x 14.5 cm x 1cm thick and is held easily in one hand when open, plus the spiral binding keeps it open at the correct page.
'The Game of Mah Jong' introduced the European and Commonwealth methods of scoring Mah Jong hands, which are more interesting and complex than the simpler original Chinese rules. To quote "This concise booklet is an authorative guide to the rules and scoring of the game of Mah Jong. Using specimen hands to illustrate techniques, it outlines the most correct and popular method of playing this fascinating game". Interestingly the Chinese characters on the right side of the cover of earlier editions translate as 'Mah Jong Rules', apparently Robertson didn't dare to put that into English - in the preface, he states that "Mah Jong players do not use one set of rules". Since then this classic book has became the most used reference standard for Mah Jong scoring. This is an essential book for anyone with three friends and a Mah Jong set.
