モバイル四川省＋一角取り/二角取り is a puzzle game that allows you to play with mahjong tiles in the famous Sichuan province. It offers various initial layouts, as well as special game modes such as ikakudori mode (where you can only remove tiles with less than one turn) and gravity mode (where empty spaces are filled from the bottom).

One unique feature of this game is the three tiles mode, where you can remove three tiles at once if any two tiles can be taken out. All placements in the game are designed to be clearable, providing a challenging yet solvable experience.

It includes a simple benchmark function to measure the processing performance of your device, a display function to show available positions, and an automatic deadlock acquisition function. Additionally, you can redo a problem from the beginning or play by specifying a problem number, making it suitable for competing with friends. The game also features a net ranking function to compare your scores with other players.

This app has been regularly updated, with the latest update in January 2022 adding five new three tiles modes. It offers a wide range of game modes and layouts, including full tile mode which utilizes all 136 mahjong tiles. Although the small size of the tiles may pose a challenge on smartphones, the game provides virtual keys for easy operation.
