Interlocking building blocks

An interlocking building block system comprising:

• a plurality of rigid, sturdy blocks including at least one standard block, at least one squared corner block, and at least two angled corner units,
• each of said blocks including a top surface, a bottom surface, and four outer faces including a front face, a rear face, a left face, and a right face, and at least one transverse bore passing through said top surface and said bottom surface,
• said bottom surface including at least one elongate, rounded, cutout channel,
• said top surface including at least one elongate, rounded, protruding ridge structured and disposed to be correspondingly positioned in engaging, securing relation within said elongate, rounded, cutout channel in an adjacently stacked one of said blocks,
• said outer faces further including at least one rounded, vertical, cutout channel extending from said top surface to said bottom surface and positioned in said left face in a substantially centered position between said front face and said rear face,
• said outer faces also including at least one rounded, vertical, protruding ridge extending from said top surface to said bottom surface and being structured and disposed to be correspondingly fitted, in engaging, securing position within said rounded, vertical, cutout channel of an adjacently positioned one of said blocks,
• said standard block and said angled corner units including said rounded, vertical, protruding ridge positioned on said right face in a substantially centered position between said front face and said rear face,
• said top surface of said standard block and said angled corner units including two of said elongate, rounded, protruding ridges extending from said left face to said right face, each of said elongate, rounded, protruding ridges being on opposite sides of said transverse bore,
• said bottom surface of said standard block and said angled corner units including two of said elongate, rounded, cutout channels extending from said left face to said right face, each of said elongate, rounded, cutout channels being on opposite sides of said transverse bore,
• said front face of at least one of said standard blocks including a rounded, protruding ridge, extending from said top surface to said bottom surface in substantially centered relation between said left face and said right face, said ridge being adapted to be fitted within the vertical rounded, channel of a perpendicularly positioned one of said blocks,
• said angled corner units including a first angled corner unit and a second angled corner unit for use in the formation of a 90.degree. squared corner,
• said right face of said first angled corner unit being angled so as to form a generally 45.degree. angle with said rear face, and said left face of said first angled corner unit being generally perpendicular to said front face and said rear face,
• said left face of said second angled corner unit being angled so as to form a generally 45.degree. angle with said rear face, and said right face of said second angled corner unit being generally perpendicular to said front face and said rear face, said left face of said second angled corner unit being structured and disposed to be fitted with said right face of said first angled corner unit so as to form said 90.degree. squared corner,
• said squared corner unit being generally square, and said rounded, vertical, protruding ridge being positioned on said front face in a substantially centered position between said left face and said right face,
• said squared corner unit including two of said rounded protruding ridges along said top surface thereof, said ridges being perpendicularly positioned along a length defined by said rear face and a length defined by said right face, thereby allowing the facilitated positioning of said angled corner units thereon, and
• said squared corner unit including two of said rounded cutout channels along said bottom surface thereof, said channels being perpendicularly positioned along said length defined by said rear face and said length defined by said right face, thereby allowing said squared corner block to be securely placed atop said angled corner units.
