A board game incorporating the Ulam Spiral in which players compete to advance along a square spiral path of natural numbers via the prime numbers which are color coded according to the order of the subsequence of primes to which they belong. A player can occupy only one position on the board at any one time, and the player's position is determined by the prime index total that is accumulated via the roll of a die at each turn. The first player to reach the first prime number above some predetermined point on the natural number line wins the game.

Methods and apparatus of associating by a computerized system, labels with the order of execution of steps of solving a puzzle, game or activity, for one or more parts of one or more solution-paths for the puzzle, game or activity are described. Execution of the puzzle solution and also the particular sequence of steps in the solution paths are used to evaluate a relative efficiency of one sequence of steps over the other sequence. By quantifying efficiency of the solution path it becomes possible to logically and objectively compare the efficiency of two or more solutions or completions of the puzzle, game or activity.

A game timer, a game board cartridge, and a plurality of game boards for inserting into the game board cartridge are provided. A play base has a plurality of grids and plurality of timer spots for receiving the game timer with each grid having a plurality of holding cells for receiving one of the plurality of numbered game tiles. A game board cartridge carrier for removeably holding the game board cartridge with the game board cartridge receives at least one of the plurality of game boards. A plurality of numbered game tiles with each of the plurality of tiles having playing tile indicia corresponding to an integer selected within the range of 0 to 9 is provided. The game board cartridge is positioned over the play base and can be rotated in relation thereto. Each of the plurality of game boards is marked with a game board grid having a plurality of rows and columns forming a plurality of squares, with each of the plurality of squares having a game board indicia corresponding to an integer selected within the range of 0 to 9, and with none of the integers repeating within the same row, same column, or with respect to a connecting diagonal square. The plurality of tiles are drawn during game play, so that a player can make a diagonal connection to score points by matching the playing tile indicia with the game board indicia during a predetermined time period measured by the game timer.

A magnetic sudoku board has a housing, a closeable lid and an inner playing surface. The inner playing surface having gridlines to form the magnetic sudoku board. An assortment of magnetic playing pieces includes a large set and small set. To distinguish between the numbers, 1-9, the assortment of magnetic playing pieces has a certain color that corresponds to a specific number. Accordingly, the same number in both the large set and the small set have coordinating colors. These colors visually assist the player so that the same numbers are not repeated in each column, row, and 33 grid box.

A game (2) comprising: a game board (11) comprising a series of ridges, each of the ridges (10) comprising a first face (32) and a second face (33), wherein the second face (33) of each ridge (10) faces toward a first player at one side (30b) of the game board (11) and the first face (32) of each ridge (10) faces toward a second player sitting opposite the first player at an opposite side (30a) of the game board (11); a playing piece (13) comprising a base (44) which corresponds to the faces (32, 33) of the ridges (10); and a die (12) comprising four or more faces (42), each face (42) indicating a numeric value (43), wherein at least one of the numeric values (43) is indicated on at least two of the faces (42).

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 puzzle game including a number map having a 99 grid filled 9 number sets, where each number set includes the numbers 1 through 9. The 9 number sets form unique shapes comprised of 9 grid squares, where each number from each number set is connected at a side of a square in the grid to the other numbers in the set. Corresponding to each number set is a tile group comprised of 9 transparent tiles of the same color, where each tile group is a different color. To solve the puzzle every tile must be placed adjacent a tile of the same color within a single number set. Same color tiles must be placed on a different number within a single number set. The puzzle is solved when each number set is covered by tiles of the same color and the grid completely covered by tiles.
