Abstract: A game. There is a game board having openings on its surface and headings, each indicating an occurrence in a competitive event. Indicia are marked on the board at each side of the openings and slides are received on the board. Each slide extends across an opening between two indicia. A blank portion on each slide aligns with an opening at a first position of the slide. Information on each slide relates to each number on each side of the opening when the slide is moved to a second position. A plurality of cards are included, each with one of the indicia that is also marked at the side of the openings. Thus, on watching a competitive event, as an occurrence takes place the slide is withdrawn at that occurrence space to indicate that the holder of a card with one indicia on it loses and the holder of the card with the aligned indicia wins.

Abstract: A game device utilizing the old and well known concept of connecting adjacent dots of a matrix of dots by utilizing a connecting line formed by a player during his period of play. In this known type of game device, the matrix of dots is usually arranged periodically in a horizontal and vertical array with the purpose of the game being to complete more squares than an opponent. The present invention provides a tri-level gameboard with each level having a number of dots thereon with each level also including a predetermined number of fixed and optional "stops" that are distinguishable by color and/or configuration to prevent a player from capturing the enclosed shape, such as a square, triangle or the like having any side composed of a "stop" thereby introducing the use of skill and strategic planning by the players inasmuch as a player, by judicious use of the "stops" can decisively control the outcome of the game.

A plurality of tiles are provided for each player, each tile being marked with one of the base 11 digits [1, 2, 3 . . . 10] for placing on the board. Each player places one tile at a time in an attempt to provide rank, file, or diagonally contiguous sequences which sum to a number even divisible by ten. A combinatorial sieve to generate all non-redundant combinations of three integers which sum to either ten or twenty is used to derive the number of tiles marked with each digit (35).

Abstract: A sensing frame is positioned so that a basketball will pass through a rectangular shaped opening in the sensing frame when a free throw shooter shoots the basketball towards a goal. The sensing frame has a beam of light directed across it above the top of the desired path of the basketball for the basketball to enter the goal and a second beam of light directed across it below the desired path of the basketball to enter the goal. If either of these beams of light is broken, different alarm signals indicate to the shooter whether the path of the basketball is high or low. The sensing frame is adjustable both vertically and about a horizontal axis to enable the desired positioning of the sensing frame relative to the shooter.

Abstract: A drawing stencil tablet to aid a child to color and draw includes a planar stencil plate having interior openings defining tracing edges that outline a character or shape. A plurality of spaced-apart locating posts project down from an edge of the plate and engage in registering openings in a stiff planar base when the plate is placed flush against an interior area of that base so that a base margin extends all around the plate. When the locating posts are received in the base, movement of the plate relative to the base is prevented so that a child can trace or draw on a sheet of paper sandwiched between the base and the plate with assurance that the position of the stencil plate on the paper will remain fixed.

Abstract: A poker game is disclosed which includes several gameboards. Each of the gameboards includes at least 52 locations, or more if the use of jokers is desired. Each of the locations displays therein a symbol of a different playing card from a standard deck of cards. Each of the locations also displays therein one of a series of at least 52 sequential numbers, which are independent of and unrelated to the playing card symbols. Either the playing card symbols or the numbers are randomly arranged on each gameboard. Each of the gameboards thus has different combinations of playing card symbols and indicia within its locations. A "wheel of fortune" is provided for randomly generating a series of numbers corresponding to the numbers on the gameboards. Upon operation of the wheel of fortune, each gameboard has associated therewith a poker hand consisting of the playing cards symbolized in the locations corresponding to the series of numbers thus generated.
