ツモ切りにゃ！ is an unofficial Chrome extension designed to assist players in the popular Mahjong game, 雀魂. This tool enhances gameplay by transforming right-click actions into double-click commands, enabling users to efficiently perform tile discards and cancel actions with ease.

The extension features recent updates that improve usability, such as fixing the click generation position to the location of the cancel button, which helps prevent unintended tile plays. Additionally, the extension allows users to assign the same functions of right-clicking to the spacebar. Note that users should enable specific settings for optimal performance, and the developer disclaims any responsibility for losses incurred through the use of the extension.
