subaku, Japanese for Number Explosion, is just as it sounds. You touch a number, it explodes (value decreases by one), then the surrounding numbers pick up some of the collateral explosion (value increases by one). Easy to learn and difficult to master, subaku will keep you entertained for hours as you devise strategies to attack each puzzle and complete them in as few moves as possible.
