A playing card having a substrate entirely of a first predetermined colour overlaid with a removable surface coating entirely of a second predetermined colour contrasting with said first predetermined colour, said removable surface being sufficiently friable so as to be able to be scratched off by a player in a pattern predetermined by said player to reveal said substrate in said pattern. The scratched playing card uses the high contrasting colors (typically primary and secondary colors) to produce letters or image(s). These cards are interchangeably used in a strategic and non gambling card game often utilising the Stroop effect.

The philosophy of games is to provide a mental challenge to the person who is playing the game. With this game a person can build the game according to that person's wants and desires and in this case a dodecahedron is used; the dodecahedron is color coded and an interior sphere is placed with the dodecahedron. Clues that have been placed in pockets of the outside surface of the dodecahedron will consist of locations where coins are hidden. These coins will be gathered and the dodecahedron is manipulated. The interior sphere contains the solution to the game or a prize and is initially locked prior to the start of the game. As the contestants play the game and solve the puzzle, the interior sphere is unlocked and the solution or prize is revealed. The game can be structured to the desires of the individual builder as often as possible.

A game server includes: a main processing unit, connected to a user terminal via a data network, configured to perform user login; and a game processing unit configured to control the user terminal to execute a puzzle game in response to a game execution request signal from the user terminal. The game processing unit is configured to: control the user terminal to display colored blocks arranged in a matrix form of N rows and M columns in a puzzle game area, and to display one game character in an action display area; exchange a selected block with another neighboring block based on user input; determine if a matching block group of at least three consecutive blocks having the same color results from the block exchanging step; remove the matching block group; and control the game character to perform an action according to a result of the block removing step.

Disclosed herein are systems and methods for dynamic generation of an intelligent and location-based puzzle. The method comprises locating a mobile device within a proximity zone associated with an establishment and generating a user dataset comprising a counter representing how many times the user has been identified within the proximity zone. The method further comprises querying, receiving, and displaying a first media element associated with a puzzle. Upon locating the mobile device within the proximity zone for the second time, the method comprises adjusting the counter value and querying, receiving, and displaying a second media element associated with the puzzle.

[Problem] In the past, a prescribed action could not be executed through an enjoyable operation. [Solution] The information processing device according to one embodiment comprises an output unit for outputting one or more blank areas corresponding to one or more items of blank area information, and one or more objects; a receiving unit for receiving a move command with respect to the object; a mover unit for moving the object in response to a move command received by the receiving unit; and an execution unit for, in cases where the position of an object moved by the mover unit exists in a predetermined positional relationship with respect to the blank area, executing an action that corresponds to the blank area or moved object.

A shower shade includes a curtain support and a curtain coupled to and hanging from the curtain support. The curtain may be made of a water impermeable material. A connector is coupled to the curtain support and is configured to releasably couple the curtain support to a shower head, a shower arm, or a shower caddy of a shower so that the curtain covers at least one hot and cold water knob in the shower. The shower shade further provides intellectual engagement.

In an aspect a modular field manipulation apparatus is presented. A modular field manipulation apparatus includes a central field manipulation device. A central field manipulation device includes a first surface having a first field polarity. A central field manipulation device includes a second surface positioned opposite a first surface. A second surface includes a second field polarity. A modular field manipulation apparatus includes a plurality of interconnecting components. Each interconnecting component of a plurality of interconnecting components includes at least a contacting member. At least a contacting member engages with at least a first surface of a central field manipulation device.

A dog toy comprises a first component having a body that defines a cavity, the body having an opening into the cavity. The dog toy also comprises a second component having a body comprising a first protrusion and a second protrusion. Each of the first protrusion and the second protrusion is selectively insertable into the first component opening in a manner where it remains within the opening to close the opening and is removable from the first component opening when a separation force is applied. The separation force for the first protrusion is different than the separation force for the second protrusion. A treat can be inserted into the first component cavity, the first component cavity can be closed by insertion of the first protrusion or second protrusion into the first component opening, and a dog can gain access to the treat by separating the first component and the second component.

Systems and methods for determining relationships between units are described. An illustrative system may include a semantic knowledge base having information regarding stored relationships between a plurality of units associated with content, a processor and a non-transitory, processor-readable storage medium in communication with the processor. The storage medium may include one or more programming instructions that, when executed, cause the processor to direct a display to present the plurality of units to one or more users, receive an input from each of the one or more users, compare the input with the information in the semantic knowledge base and determine whether the input corresponds to a stored relationship and provide a notification to each of the one or more users based upon the determining. The input may correspond to a determination of a relationship between the plurality of units based upon the content of each unit by a user.
