BeijingOperaPuzzle is a puzzle casual game that involves elimination. Its rules are very simple, as long as you click on the space, you can eliminate the same faces in four directions, up, down, left, right, and so on, until the game wins after eliminating all the faces. The more faces of the same type are eliminated with each click, the more scores and rewards will be obtained. However, due to limited space, faces, and steps, each choice is very important. The initial choice may affect the final result. Easy to get started, difficult to master, more like a chess game that emphasizes strategy and prediction.
