A playing board for sliding body games, such as curling and shuffleboard, is herein disclosed. The playing board is formed with irregular surfaces and asymmetrical sides to increase the complexity of the games played on the board. In certain embodiments, various configurations of peaks and valleys can be incorporated that influence a direction, speed, or both of a sliding body that is travelling on the playing board.

A marble jump game includes a base, a tube, a marble track, and a plurality of targets. The tube is configured to be removably secured to a corresponding tube of a receiving tube of a marble run module having a receiving tube. The tube defines an axial direction, and is supported at least indirectly by and above the base. The marble track is affixed to the tube, and extends from a first end to a marble exit. The marble track is configured such that when the axial direction is vertically oriented, a marble placed on the marble track proximate the first end traverses the marble channel and exits through the marble exit. Each target of the plurality of spaced-apart targets is with a game value. Each target has a fixed position relative to the others of the plurality spaced-apart targets.
