RS4 gameIn this game, you select a box and then select another, and reverse the part between them(including them). That's when the name came from although it's a bit misleading because RS4 means "reverse 5 boxes" :)
Your goal is to arrange the boxes so that there are four squares on the board (order matters). Press "show target" to see it.
This game uses cool CSS3 3D features, as well as Workers for solver, so that the UI won't be frozen during the search process.
You can bookmark the URL to play the same board again.
If this game is not what you initially thought it was, then maybe the encore version will be what you thought it was :)
