Abstract: A board game includes a chessboard having squares arranged in a pattern on the chessboard; and pieces adapted to place on the squares respectively, each piece having a no-mark face-up side and a face-down side with either of diagonal lines or a grid of lines being printed thereon. The pieces with the diagonal lines are identified as one side and the pieces with the grid of lines are identified as the opposing side. Either side has one half the number of the pieces. The face-down side of each piece is marked with a scissors, a rock, or a paper. The pieces belonging to either side are grouped as the scissors pieces, the rock pieces, and the paper pieces, all being equal in numbers. The board game is particularly intended to be played by two individuals such as children or non-Chinese adults who cannot read Chinese characters.

Abstract: A strike trainer includes a main frame adapted to abut against a supporting surface and a striking device mounted on a top portion of the main frame. The strike device includes a weighted element secured received in the top portion of the main frame and a resilient member having a first end engaged to a lower end of the weighted element. A rope has a first end securely connected to a second end of the resilient member and a resilient post having a first end secured in the top portion of the main frame and sleeved on the rope. A ball is secured on a second end of the rope after extending through the resilient post and abuts a second end of the resilient post due to a restitution force of the resilient member.
