Left: king, jade 王, right: strange/odd 奇 (There is a big 大 possibility (opportunity) 可, but it looks strange.) [possibility 可 = The nail 丁 into the opening 口 should be possible.]
Mnemonic
This 'jade' gives big possibilities, because it is a gem.
The app has many other functions, such as character selection according to difficulty, practice programs, handwriting recognition and success statistics!
