Abstract: A slider puzzle with an assembly of slide members is provided. Each slide member intersects with at least one other slide member at an intersection point and is moveable between two end stop positions or any number of positions in between. Each slide member is also provided with a gate selectively located at each intersection point in accordance with a pre-determined sequence or sequences of moves. The gate either allows or prohibits movement of an intersecting slide member relative to the gate between the two end positions in whole or fractional increments. The object of the slider puzzle is to move all slide members in order that the puzzle is in a solved configuration.
