モバイル四川省＋一角取り/二角取り

Also known as Nikakutori, this mahjong tile game originates from the well-known Sichuan province and rivals Shanghai (Mahjong Solitaire) as a well-known mahjong tile game.

In addition to various initial layouts, this app also offers Ikakutori mode (a mode in which tiles can only be captured if the number of turns is one or less) and gravity mode (empty spaces are filled underneath).

You can also play in San-Tai mode, in which three tiles can be removed at once. In this mode, tiles can be removed if any two tiles are Nikakutori-captureable.

All layouts are designed to be clearable.

Furthermore, the app is highly advanced, with the following features included:

Features
- A simple benchmark function that measures the processing power of a device by repeatedly creating problems and having the AI solve them.
- A function that displays available positions.
- A function that automatically detects stalemates.
- A function that restarts the same problem from the beginning.
- A function that allows you to play by specifying a problem number. The same puzzle number will be placed in the same position across platforms, making it ideal for competing against friends.

Online ranking function.

You can also play Mahjong Solitaire, a game in which you eliminate tiles by combining tiles that have no tiles on either side.

Similar to Sichuan Province, it is a classic Mahjong game.

While the game is simple and not heavy, it includes many initial positions and convenient features.
