Riegel, which was designed by Paul Schobesberger (Austria), is an abstract game played on wooden board with 10 rows of sliders. Each row has depressions to hold marbles. Each player is trying to get their set of marbles from one side of the board to the other, but can only move onto certain depressions and thus the sliders must be positioned properly for movement. Made by Felsberger in the same high quality as their other games. It is not an abstract strategy game since the moves are decided by dice according to http://toy-net.ch/felsberger/spielregeln/riegel.htm .
