Mahj Call is an independent American Mahjong app designed to make learning and playing welcoming for newcomers and experienced players alike. Available for iPhone and iPad, it guides beginners through a first game with Helena, then offers twelve short lessons that can be taken in any order. Players can practice complete hands, from the deal and Charleston to calls, jokers and Mahjong, against three friendly bots at a relaxed pace. The Coach highlights promising hand options, and larger tiles are available for easier viewing.

The app also features three free Daily Mahj Puzzles, including challenges to find a hand, judge whether hands qualify for Mahjong and identify tile sections. Players can earn charms through games, lessons and puzzles, then spend them on hand-drawn tile sets and table mats. For social play, Mahj Call offers private tables with customizable house rules and Quick Match. These features, along with unlimited practice, are included in a paid membership; everyone receives a free practice hand daily.
