Sjoelen is also known as Dutch Shuffleboard and Jakkolo. Sjoelbak is the name of the board, not the game itself.Playing involves each player having three chances to slide wooden disks along 6 foot table in an attempt to get them through four arches numbered 1 to 4 at the other end. Getting disks into the low scoring compartments is just as important as the high ones because each set of 4 disks in the four compartments scores double (20 instead of 10 points). - BoardGameGeek
