Augmented reality and physical game techniques are described. In one or more implementations, an indication is received by a computing device of a location of a physical gaming piece of a game. An augmentation is computed based on the indication by the computing device to be displayed as part of the game. The augmentation is displayed by the computing device on a display device that is at least partially transparent such that a physical portion of the game is viewable through the display device concurrently with the augmentation.

A two-card sleeve apparatus is described. The two-card sleeve apparatus may include a first transparent layer, an opaque layer, and a second transparent layer. The two-card sleeve apparatus may be used to safely store or display two or more trading cards.

An overlay having artwork printed thereon in a strategic location such that when placed over the front face of a card changes the look and appearance of the original artwork on the front face of the card. The overlay may be used with any type of card, but is preferably used with playing cards and trading cards, and is most preferably used with collectible trading cards.

A puzzle building block capable of changing light-emitting areas includes a building block board, a circuit board, light-emitting elements and building bricks. The building block board includes a plate body and connection portions. The connection portions are disposed on the top surface of the plate body. The circuit board is adjacent to the bottom surface of the building block board. The light emitting elements are disposed on the circuit board, and the light emitted from the light emitting elements passes through the building block board via the connection portions. The building bricks are fitted with the connection portions and shield the corresponding connection portions, thereby forming letters or patterns. Therefore, the light emitted from the light-emitting elements can form various letters or patterns on the top surface of the building block board. The present invention also provides a puzzle building block assembly including the above-mentioned puzzle building blocks.
