Opening claim text (preview).
What is claimed: 1. A practice putting device that includes: a rollable putting mat; and a housing including a midportion about which said putting mat is rollable and unrollable, a first end portion connected to one side of said midportion, and a second end portion connected to the opposite side of said midportion; each of said first and second end portions of said housing having an exposed outer peripheral surface shaped to be rollable directly on a floor surface to roll said putting mat up onto said housing by winding said putting mat about said midportion of said housing, and to unroll said putting mat from said housing. 2. The practice putting device as defined in claim 1 , further comprising a side ball return arrangement; said side ball return arrangement including a side return mat; said side return mat is rollable up onto and unrollable from said housing; said side return mat is a separate mat from said putting mat; wherein said side return mat has a) a width that is less than the width of the putting mat, b) a length that is the same or different from a length of said putting mat, and/or c) a thickness that is less than a thickness of said putting mat. 3. The practice putting device as defined in claim 2 , wherein an end portion of said side return mat has a side return mat weight, to facilitate in maintaining a flatness of said end portion of said side return mat after being unrolled from said housing and a ball stop to inhibit or prevent a golf ball from rolling off a back end of said side return mat. 4. The practice putting device as defined in claim 2 , wherein said side return mat includes a) a center groove to facilitate in maintaining a golf ball on said side return mat as the golf ball rolls along said side return mat, and/or b) one or more side walls to facilitate in maintaining a golf ball on said side return mat as the golf ball rolls along said side return mat. 5. The practice putting device as defined in claim 2 , wherein one of said first and second end portions incudes first and second flanges; a spacing between said first and second flanges is the same as or greater than a width of said side return mat so that said side return mat is rollable onto and rollable off one of said first and second end portions. 6. The practice putting device as defined in claim 1 , wherein a top surface of said putting mat includes markings to provide information to a user; said markings include one or more of distance markings, one or more lines along a longitudinal length of the putting mat to inform a user how straight a putted golf ball travels along said putting mat, and/or markings to indicate one or more targets on the putting mat. 7. The practice putting device as defined in claim 1 , wherein a front-end portion of said putting mat includes a weighted device to facilitate in maintaining a flatness of said front end portion of said putting mat after being unrolled from said housing. 8. The practice putting device as defined in claim 1 , wherein a front-end portion of said putting mat includes a connector used to releasably connect a top surface of said front end portion to a bottom surface of said putting mat when said putting mat is rolled up onto said housing. 9. The practice putting device as defined in claim 1 , wherein: a maximum cross-sectional area of said midportion of said housing is less than a maximum cross-sectional area of one or both of said first and second end portions of said housing; and a spacing between said first end portion of said housing and second end portion of said housing is the same or greater than a width of said putting mat so that said putting mat is rollable about said midportion and is partially or fully located between said first and second end portions of said housing when said putting mat is fully rolled up on said housing. 10. The practice putting device as defined in claim 9 , wherein the exposed outer peripheral surface of each of said first and second end portions of said housing has a generally circular or oval shape so that said outer peripheral surface of each of said first and second end portions of said housing is rollable on the floor surface; at least one of said first and second end portions of said housing includes a floor orientation arrangement, in the exposed outer peripheral surface thereof having the generally circular or oval shape, that facilitates proper orientation of said housing relative to said putting mat and the floor surface once said putting mat is fully unrolled from said housing onto the floor surface; said floor orientation arrangement limiting or preventing rocking of said housing on the floor surface once said putting mat is fully unrolled from said housing on to the floor surface. 11. The practice putting device as defined in claim 2 , wherein said housing includes a ball well to receive a golf ball that has moved past a back end of said putting mat or has fallen through a golf ball opening located at or near a back-end portion of said putting mat; said ball well is configured to cause the golf ball in said ball well to be fed to said side ball return arrangement. 12. The practice putting device as defined in claim 11 , wherein said side ball return arrangement includes a return opening located in one of said first or second end portions; said return opening to enable a golf ball to exit said ball well and to move on to said side return mat. 13. The practice putting device as defined in claim 11 , wherein a front portion of the side ball return arrangement is elevated above the floor surface when said housing is positioned on the floor surface and said putting mat is fully unrolled from said housing; wherein said front portion of said side ball return arrangement forms a downward ramp portion of said side return arrangement to cause a golf ball to roll downwardly toward the floor surface on said downward ramp portion. 14. The practice putting device as defined in claim 1 , wherein at least one of said first and second end portions includes one or more golf ball slots and/or cavities to store one or more golf balls on said at least one of said first and second end portions. 15. The practice putting device as defined in claim 1 , wherein said housing includes a bubble level used to indicate to a user whether the floor surface on which said housing is sitting is level. 16. The practice putting device as defined in claim 1 , wherein said outer peripheral surface of at least one of said first and second end portions of said housing includes a floor orientation arrangement that limits or prevents rocking of said housing on the floor surface once said putting mat is fully unrolled from said housing on to the floor surface. 17. The practice putting device as defined in claim 16 , wherein said floor orientation arrangement comprises a flat portion on said outer peripheral surface of at least one of said first and second end portions of said housing. 18. The practice putting device as defined in claim 1 , wherein said midportion of said housing includes a flat mount surface that supports an end portion of said putting mat; wherein said flat mount surface includes an opening that is aligned with an opening in said putting mat and that allows a golf ball to pass therethrough. 19. The practice putting device as defined in claim 18 , wherein said flat mount surface has an upward angled orientation when said putting mat is fully unrolled from said housing and said housing is properly situated on the floor surface; said upward angled orientation causing a rear end portion of said putting
