Patent number: 10625166Abstract: A sliding loop game with move constraints includes a playing field formed by intersecting strings and loops. Each loop is a selfconnected chain of sites. Each string consists of a chain of sites. Both ends of a string are virtually connected in a loop via invisible connecting sites. Each site is occupied by a game object specifically marked by a color, pattern, character or characters, number, image, or any other identifying marks. Game objects in a loop or a string are moveable as a whole group along the respective sites in the loop or string. If the game object at the endsite of a string leaves the string, it reappears in the endside at the other end of the string. Movement constraints are applied to the game objects by using master game objects. Hints on target positions of game objects and allowed movements directions are indicated on the playing field.Type: GrantFiled: May 29, 2018Date of Patent: April 21, 2020Inventors: Sergey K.

Patent number: 6089871Abstract: A method and apparatus for teaching mathematical skills to players of all ages includes a game board having 100 spaces printed on a first board side, the spaces numbered from one to ninetynine and having one logo space. Each space, in addition, has printed on it a prime number factorization, an exponential representation, or both, corresponding to the number contained within the particular space. Each player rolls a plurality of dice having prime numbers assigned to each die face. The object of the game is for players to score points by occupying board spaces between spaces imprinted with prime numbers. A space is occupied by applying the rolled dice to match a prime number factorization of a particular space, whereupon a chip is placed on the particular space to denote ownership. The dice used to occupy a space are then no longer used for occupying other spaces during a round of play.Type: GrantFiled: March 8, 1999Date of Patent: July 18, 2000Inventor: Andrew P. Jaffe

Patent number: 6079983Abstract: An educational instrument for numbers for providing students with an educational tool that would be fun and challenging. The educational instrument for numbers includes a base member having a top side, a recessed portion in the top side, a first longitudinal slot, a second longitudinal slot, a first longitudinal groove extending from the recessed portion and terminating near a first end of the base member, a second longitudinal groove extending from the recessed portion and terminating near a second end of the base member, a matrix of numbers disposed in the recessed portion, a first cover means slidably disposed in the first longitudinal slot and movable over the recessed portion, and a second cover means slidably disposed in the second longitudinal slot and movable over the recessed portion and over the first cover member.Type: GrantFiled: December 3, 1999Date of Patent: June 27, 2000Inventor: James T. Kane, Jr.

Patent number: 6077079Abstract: An educational board game which is used with a conventional deck of playing cards. The game includes a board which has a matrix of spaces in vertical and horizontal rows. Some of the rows are guide rows containing suit and numerical value indicia relating to the playing cards. The remaining spaces contain numerical values having a mathematical relationship to corresponding spaces in the guide rows. Each of the remaining spaces is covered by a removable tile that bears the numerical value of the space and one of the suits of the playing cards.Type: GrantFiled: May 22, 1998Date of Patent: June 20, 2000Inventor: Latrell Barnes

Patent number: 6065970Abstract: A method of playing a game which includes (i) a game board which is divided into a plurality of sections such that each of the sections defines a playing location, (ii) a number disposed on each of the playing locations, (iii) a plurality of cards, and (iv) a number disposed on each of the cards is disclosed. The game includes the steps of (a) providing a game player with a multiplicity of the cards, (b) the game player determining if the number indicated on any one of the cards is a first mathematical multiple of the number indicated on any one of the playing locations, (d) removing from the multiplicity of the cards a first card that has the number indicated thereon which is the first mathematical multiple of the number indicated on one of the playing locations, and (e) positioning the first card on one of the playing locations such that the number indicated on the first card is the first mathematical multiple of the number indicated on the playing location on which the first card is positioned.Type: GrantFiled: April 13, 1999Date of Patent: May 23, 2000Inventor: Karen Crawford Elliott

Patent number: 6062566Abstract: A dominosstyle mathematical operation game is provided including a plurality of dominos each having a top face and a bottom face. The bottom face of each domino has a pair of equally sized sides each with a unique combination of a number indicia and a mathematical sign.Type: GrantFiled: February 12, 1998Date of Patent: May 16, 2000Inventor: Lemuel W. Lemons

Patent number: RE37212Abstract: A tape measure is provided in which orientation of the primary indicia are varied to allow reading of measurements from either side. A centering strip is provided which gives fractional values corresponding to the primary indicia, thus allowing easy calculation of certain fractions of a given measurement. Other visual aids for improving ease of use are provided, such as stud centering marks, distinct colors and variations in numeral and hatch mark sizing.Type: GrantFiled: December 17, 1999Date of Patent: June 12, 2001Inventor: Forrest A.
