Bought this to replace an older set which had some tiles missing. This set has slightly smaller tiles but exactly the same number of tiles and patterns as my old set and the tiles are also made of the same high quality material. One strange thing I've noticed - the booklet in the new set doesn't feature some of the puzzle formations that are listed in the booklet which came with my old set but which are obviously still playable with this new set seeing that the tiles are exactly the same patterns as my old set. Good price for a 'solitaire' puzzle which features many puzzle variations as well as being playable against opponents as 'games'. This will last for many years because of the quality of the materials and the puzzles will keep you going for many more years to come - they get harder and harder as the number of tiles are added to each puzzle combination.
