Abstract: A putt practice device includes an elongated, thin, planar base having a carpeted upper surface, a putting end, and a target end. A pair of spaced rows of pegs extend upwardly from the planar base. Caps consisting of cut off golf tees having holes drilled into their lower ends are placed on the two rows of pegs, defining a putting path along which a sufficiently accurately putted golf ball can roll without touching any of the modified golf tees on either side. A removable ball stop is attached to a pair of the pegs at the target end of the putt practice device. The putt practice device also can be utilized on a putting green by removing the ball stop, and aiming the longitudinal axis of the putt practice device toward a hole on the putting green. If the surface of the putting green is sloped, the orientation of the practice putting device can be aimed to one side or the other of the target hole to compensate for slope in the putting green surface.
