The present golf putting simulator device includes an elongated body member which tapers from the back end where the ball is putted to the front end where a golf ball cup-like opening is provided. The body member includes an upper putting surface and channel members which extend along each side of the body member from the forward portion to the rearward portion. Each channel member is provided with a base surface which is positioned angularly to slant from a high forward end position to a low back end position whereby golf balls entering either channel will gravitate from the forward end to the rearward end.
