很好但有点小bug
有时候肯肯数独的四则运算符号显示不出，只有数字，删除重装会变好

你好，肯肯数独里没有运算符号的话，表示可以用 加减乘除 任一运算哦，可参见题型“玩法说明”
Not in English!
Not sure how we’re supposed to use this if nothing is in English.
Response from developer
v3.9.6 already use device language as app's default language, please upgrade. Sorry, previous app defaults to Chinese. You can switch the language to English on the "About" page (the last tab button at the bottom of the homepage).
