The invention relates to a compartment (13) for aboard game box, comprising a rectangular bottom (130); three walls (132, 133, 134) perpendicular to the bottom and rising up from three sides of the bottom, respectively; a wall (131) that is mounted movably relative to one side so as to be actuated between a high position such that the four walls close the sides of the bottom and a low position such that one side is accessible; and means (1360, 1361, 1361, 1370, 1371, 1371) for returning the movable wall (131) to the high position when it starts to be raised.

A toy top includes a body and a bump for attack which is disposed on a circumference of the body. The bump moves up and down according to a force acting on the bump while the toy top spins.

A toy top includes a shaft part having, as a shaft center, an axis that coincides with a center of rotation. A lower end portion of the shaft part includes a shaft tip part and an annular member. The shaft tip part includes a contact member. The annular member is movably disposed around the shaft tip part in an extending direction of the axis. In a normal state in which the axis is perpendicular to a contact surface, the contact member protrudes from the annular member downward, and only the contact member contacts the contact surface. When the axis of the shaft part inclines with respect to the contact surface, the contact member and the annular member contact the contact surface.

A game apparatus including a plurality of first and second player game pieces, each having a first portion that is a chess piece, such that the plurality of first and second player game pieces include all the pieces for a first and second player, respectively for a game of chess. Each of the plurality of first and second player game pieces has a second portion fixed to a corresponding first portion. Each second portion has a recess so that a cube can be inserted into the recess so the cube cannot be seen from a front of the second portion. The game apparatus may further include a base; a grid; and a first and/or second plurality of insert pieces. The grid and the base form a chessboard pattern of a plurality of grid spaces. Each of the insert pieces fits within a space of the plurality of grid spaces.

A balancing device which includes a plate which can be affixed to an object to be balanced, a balance member to be removably affixed to the plate, a support, and both the balance member and support having each one of a pointed spike and concave depression which receives the pointed spike. A user affixes the plate to an object to be balanced and attaches the balance member to the plate. Thereafter, a user places the object on top of the support resting on a surface so that the pointed spike is inserted into the concave depression. The object balances upon the support at an angle which can be adjusted by moving where the balance member is attached on the metal plate.

A system and method for teaching arithmetic has a plurality of training aides or manipulatives wherein a child/student learns arithmetic facts by executing the method using the system. The physical training aids may include a plurality of dice (10,12), a numerical board (20), a plurality of pennies (26) and a container (22). The physical training aids are used with the child where the child creates addition/subtraction problems by rolls of the dice (10,12) wherein the child uses the numerical board (20) and container (22) along with the pennies (26) to solve problems and verify answers by direct observation. Games may be incorporated where the child can use the system and method in playing the games.

A new game piece chamber has a front surface, a rear surface, and an interior. Spaced apart railings extend in parallel from the front surface to the rear surface and have smooth surfaces facing the interior. A securing mechanism is attached to the railings opposite the smooth surfaces. One or more dividers are configured to be removably secured to the securing mechanism and to organize game pieces stored in the interior. A new game board chamber has a first side and a second, opposing side and a securing mechanism on at least one of the two sides. One or more game piece holders are configured for removable attachment to, and repositioning on, the securing mechanism. A game board organizer is attached to the first side or the second side. A new modular gaming case is configured to house game piece chambers and game board chambers.

A game apparatus including a plurality of first and second player game pieces, each having a first portion that is a chess piece, such that the plurality of first and second player game pieces include all the pieces for a first and second player, respectively for a game of chess. Each of the plurality of first and second player game pieces has a second portion fixed to a corresponding first portion. Each second portion has a recess so that a cube can be inserted into the recess so the cube cannot be seen from a front of the second portion. The game apparatus may further include a base; a grid; and a first and/or second plurality of insert pieces. The grid and the base form a chessboard pattern of a plurality of grid spaces. Each of the insert pieces fits within a space of the plurality of grid spaces.

A fragrance infusing dice container and a method of infusing dice with a fragrance are disclosed herein. In particular, the container includes an enclosure defining an interior area within which a fragrance diffuser is disposed. A dice holder is also disposed within the enclosure with a plurality of dice retention openings sized to receive dice therein. The dice holder, and in particular, the dice retained thereby are fluidically arranged with the fragrance diffuser such that application of a scented oil to at least a portion of the fragrance diffuser causes the scented oil to at least partially diffuse and permeate within the enclosure and impart upon the dice.
