Mono -puzzles- vs モバイルペグソリティア Uso & Estadísticas

This is a puzzle game where the goal is to make the number of stones (black circles) on the board just one. Each stone can jump over another stone next to it in the vertical and horizontal directions. The stone that is jumped over disappears, reducing the number of stones on the board by one. Keep doing this until there is only one stone left on the board.
