Mahjong Solitaire is an online gaming site dedicated to free, browser-based Mahjong puzzles. Players can start without registering and enjoy the game on desktop computers, phones, and tablets. The site offers a range of tile layouts, including Anchor, Bridges, Fortress, Standard, and other designs, with options to choose a game or select one at random.

In each puzzle, players remove matching pairs of tiles that are not covered and have at least one open side. The aim is to clear the entire layout. Game controls include New Game, Shuffle, Undo, and Hint, while on-screen indicators track time, score, and remaining pairs. The site also keeps personal statistics and provides guidance on rules, tactics, and visual strategies to help players plan moves and avoid blocking useful tiles. Mahjong Solitaire is presented as both an entertaining logic puzzle and a way to practise visual attention. The interface and instructions are available in multiple languages, including English, Japanese, Italian, Chinese, German, French, Spanish, and Portuguese.
