A golf system that includes a tee or other area for striking a golf ball; and a golf green having a concave surface with a ball receptacle located at the lowest point in the surface so that a ball landing and remaining on the green will roll into the ball receptacle. The green includes a resiliently compressible layer coinciding with the concave surface. The resiliently compressible surface may include at least one layer of corrugated plastic material and may be covered with an artificial turf surface. The concave surface may be angled at approximately a 1:4 pitch, and the rear of the green may be approximately one-half times higher than the front thereof. The golf system may include a ball sensor that senses when a ball has been received in the receptacle. The golf green may be mounted on a portable frame.
