Translating as "By the Width of a Tire," this game covers a Tour de France-type of bicycle race. Each player takes control of a four-member racing team, and the goal is to score as many points as possible for the whole team. Movement is primarily handled by dice, however a limited card set partially replaces die results. Once you add unique rules which allow riders to draft one another and multiple kinds of road surfaces, this game has much to offer race fans.
Published in 1991 was the more widely held reprint (Jumbo also produced a Dutch edition called Demarrage!).
Homas Tour is the original edition of the cycle racing game later known as Um Reifenbreite. Many copies of the original game were destroyed in a warehouse fire in 1979. The combination of its sudden rarity and recognition as a good game meant that Homas Tour was (and is) very desirable, particularly to collectors. Everyone else can save their money and enjoy Um Reifenbreite!

BLUE is from the series Factor-5 and is the first jigsaw in which you can compete against other players. You must quickly find suitable pieces to make the jigsaw and then swap the pieces which are the wrong colour - you will be surprised by how many possibilities there are. The games in Factor-5 each consist of five nearly identical jigsaws. Each jigsaw has a letter identifying it (A, B, C, D and E), towards the up-per left corner.

The piece of the jigsaw with the identifying letter is the Starting piece. Each jigsaw has the same picture, but a total of 43 different objects in the picture have different colours.
