Dark Chess, developed by UnknownProjectX, is a board game app available on Android 9.0. It is a unique twist on the traditional game of Chinese Chess, with a new set of rules that make it an engaging and challenging experience for players of all levels.

In Dark Chess, only higher level chess pieces can capture lower level pieces. If all of your chess pieces are captured or you are unable to make a move, you lose the game. This rule adds a new level of strategy and complexity to the traditional game of Chinese Chess.

The app is easy to navigate, with a clean interface and intuitive controls. The graphics are simple yet effective, with a dark color scheme that fits well with the game's name. Overall, Dark Chess is a great choice for players looking for a fresh take on a classic game.
