Abstract: A sliding tile puzzle in which a series of rectangular tiles having exposed upper surfaces marked with indicia are packed together in a square planar array for lateral sliding movement in the planar array into a vacant space to change the relative positions of the tiles in the array thereby altering the indicia sequence. Tile turntables are mounted in four corners of the array so that tiles can be slid laterally thereon and are connected by gears to a handle shaft which extends perpendicularly below the array and which can be pushed axially upwards and twisted to raise the corner tiles above the plane of the array and rotate them for return to the array in a changed angular position. Upward movement of the shaft also raised a locking plate into engagement with adjacent tiles to prevent movement thereof.

Abstract: A game device has a series of annular wheels with exposed game indicia carrying facets around perimetrical edges and rotatively mounted in stacked, face-to-face relation on an axle rod extending from a handle housing part mounting an LCD display and mode operating buttons. An actuating and locking ring button is mounted on a free end of the axle rod. Wheel interiors are provided with coded areas identifying rotational positions and detected by detectors on the axle rod identifying wheel sequence and rotational positions corresponding to combinations of aligned indicia such as letters, the sensors providing corresponding signal to a microprocessor in the handle programmed to compare words with a dictionary in memory and calculate a players score for display on the LCD. The coded area can be bar codes or apertures for detection by a scanning head driven along the axle or circuit board mounted contact protuberances.

Abstract: A money counting game or contest in which one or more players attempt to manually count large amounts of currency within a predetermined, relatively long period of time to win a prize. Audio and video monitoring apparatus are provided to record the players.

Abstract: A hand-held puzzle comprising an planar, square array of mirror surface tiles confined for sequential planar movement via a ninth, vacant, tile size space or to alter the positions of individual blocks in the array. A humanoid character molded in one piece from elastomeric material has hands and feet anchored to preselected respective corner tiles by adhesive so that the limbs torso can be twisted, intertwined and contorted into stable different configurations by such sequential movement of respective tiles. The character's body is marked with black and white stripes which extend in straight manner along the limbs and torso when the body is undeformed enabling the direction of distortion of the limbs body to be more readily perceived by a player.

Abstract: A copy preventing sheet-form screen comprises a lenticular screen formed by a sheet of transparent plastic material having, a series of adjacent lens portions with major optical axes perpendicular to the front face and a series of light blocking striae located spaced apart underlying respective lens portions. The striae extend across a major part of the major optical axes so that when covering a sheet printed with meaningful information, the screen enables the information to be easily seen when viewed obliquely in ambient white light but prevents a meaningful copy thereof being made by conventional, perpendicularly aligned, phototransference techniques. The screen can be attached to the printed sheet by adhesive or formed as an adhesive tape to cover only preselected areas of printing. The screen may also form one or both sides of a security envelope enclosing the printed sheet and sealed by a security label carrying an authorized signature.

Abstract: A puzzle comprises a plurality of puzzle elements held together along a common axis. Each of the puzzle elements includes first and second faces and a peripheral edge. A series of discrete symbols are formed along the peripheral edge of each element. Preferably, the puzzle elements are magnetic wheels held together by magnetic forces. The magnetic wheels have a series of protuberances on one face which are adapted to register with a series of cavities on an opposing face of an adjacent magnetic wheel. The magnetic wheels are rotated relative to each through a series of click-stops which correspond to discrete positions of the magnetic wheels. A solution is achieved when all of the symbols on each of the magnetic wheels are properly aligned.
