    "Summon the JSON is awesome. Such a great idea for a game. Playing solo or with techie friends, it’s a fun way to stay sharp and even learn some new JavaScript functionality. This would be an awesome Christmas or birthday gift for anyone who likes JavaScript.'

    "STJ is unique for me because it implements in a correct, intuitive, and fun way, the complex task of teaching you and reminding you of some programming concepts. People who know, call that mechanism “gamification”. So, STJ is just that, a great gamified programming deck of cards."
