Shumujong (digitz mahjong) is a unique new mahjong style puzzle. Instead of matching symbols, your task is to match numbers to equal the necessary sum in order to clear the board. You can use any digits to make the needed number. Be careful of which numbers you choose so you don't run out of matches!
