This free on-line version of the Rush Hour Game was originally posted here at the MathCounts website (https://mathcounts.org/Page.aspx?pid=1512), who in turn got it in from the ThinkFun website (http://www.thinkfun.com/mathcounts/play-rush-hour).
I remember when I first got the ‘real version’ of this game on a road trip during a family reunion in Canada. Warning: This game is addictive and can be very frustrating at times.
I highly reccommend this game. I think it would make a great logic game for the classroom.
