Backgammon Circle

This Backgammon variant is based on an illustration of the games book of Alfonso el sabio X., dated around 1200. It is for 2 to 6 aged 8 and up.
Rules are very similar to Backgammon. 2 on a field are a block. You begin with your 4 pawns on your start field. You move with two dice clockwise. If you roll a double you can roll again after moving. In difference to backgammon you can only capture with the number on the red die or in combination with the red die. You must reach your start field with the exact number.
The flexible board is made by serigraphy and the 24 wooden pieces are hand colored. Other material is 2 dice and 6 target cards.
