An instructive board game combining solving mathematical questions and making moves on a board in the manner of the well-known game of Tic Tac Toe is disclosed. The board displays mathematical values to be used in an operation in one location, and possible mathematical results in an array at another location. After one player selects a mathematical value, another player selects another mathematical value which will when subjected to the operation, will yield a mathematical result corresponding to a result shown at a desired location on the board. The second player then occupies that location. Players attempt to occupy abutting locations arranged three in a row, vertically, horizontally, or diagonally. In one implementation, the game gives players practice in solving quadratic equations.

The invention relates to educational board games having a game board in which players compete to place player pieces on three consecutive grid spaces in a line on the game board during gameplay by selecting a subset of function cards dealt to the players, where each function card specifies one or more grid spaces on which a player piece may be placed, and one or more conditions that must be satisfied in order to place the player piece on the one or more grid spaces, and methods for playing the board games. Each function card represents a program having functions that specify a grid space on which a player piece may be placed. If a function returns true (e.g., the conditions are satisfied), then the player may place a player piece on that grid space. Otherwise, the player may not place a player piece using the function card.

A field of play may include linearly arranged locations in which a game piece, e.g., representative of a letter, may be played, in an attempt to form words. An example field of play includes a 55 grid formed of squares. Each playable location in the field of play is randomly assigned a unique integer number from 1-n, where n is the total number of playable locations. Each of two or more players use identically shaped fields of play, but having different randomly assigned numbers. Players take turns placing letters in their field of play to form words and, as they do so, the same letter is automatically placed into all opponent's fields of play at the same numbered location, thereby obstructing the opponent's progress in forming his own words in his own field of play. Scoring may be based on the number and length of words formed by each player.

The present invention relates to puzzle games, and more particularly to a symbol-based puzzle game where the user solves the puzzle by filling puzzle boxes with pre-selected symbols.

A class of games and activities of skill and logic, particularly puzzles based on reason and logic are described. Disclosed are a method and a system for comparing solutions to the puzzles based on the paths to solution and for completion of the activities based on the order of carrying out the steps of the activity. A number of applications of the method are disclosed for development of further puzzles and activities from the initial puzzle or activity, as well as for other enriching experiences and expressions, particularly the method of providing a priori or real time hints to a participant to solve the puzzle or advance in the activity. Also disclosed is a particular, novel method for participation by remote audience in logic and skill based activities such as creating or improving known logic puzzles and wagering.

A circular logic puzzle The CIRCULAR puzzle has similarities to Sudoku and Latin squares in problem solving, and in this new circular format the many different varieties of game play and playing surfaces can be produced gives many new challenges and perspectives for those who enjoy solving logic puzzles.

A three-dimensional object for use as a puzzle, has a plurality of faces, each face having a locations and numbers at each location. Some of the numbers are replaceably removable, remaining numbers being fixed, and a predetermined rule links all of said numbers on the different faces to enable correct replacement of the removed numbers to solve said puzzle.

A mathematical puzzle game includes a book that has a plurality of pages. Each of a plurality of puzzles is printed on an associated one of the pages and each of the puzzles is selectively solved for entertainment purposes. A plurality of pre-determined numbers is printed on each of the puzzles. Selected numbers are written on each of the puzzles such a sum of a pair of the selected numbers equals an adjacent one of the pre-determined numbers.

Systems for operating a Sudoku style hybrid game are disclosed. Sudoku style hybrid games can include a themed entertainment game in which a player places symbols into a Sudoku puzzle and events within the entertainment portion of the Sudoku style entertainment game can trigger wagers in a real world game of chance. Players may compete against each other to determine a winning player based on the amount of time taken to complete the puzzle of the Sudoku style entertainment game. The outcome of the wagers can result in payouts of real world credit and can also affect gameplay within the Sudoku style entertainment game.

A board game kit includes a Sudoku board, a set of board markers, and a plurality of standard six-sided dice. The board game kit is useful for providing a Sudoku board game for competitive play by a plurality of players.
