(V3.3) solutions to all levels in worlds 1 to 12

June 9, 2013

NEW: Click here if you want to try some new graBLOX levels, and to find out how to send me your levels.


Because people keep asking — here are solutions to all the levels in GraBLOX v3.3. I use “chessboard notation” as explained here — basically a1 is the bottom left square, h1 is the bottom right, and h12 is the top right.

In v3.3 of graBLOX, MobilityWare’s recommended number of moves is too big for levels 11-16, 12-11 and 12-18 and possibly others.

According to my computer program (which may have bugs!) the solutions above are minimal solutions to all the levels in worlds 1 to 10, other than 6-18 and 09-24 for which I’m not sure, because the levels are too complicated to solve by brute force. My computer is currently working on levels 11 and 12 to see if it can find any solutions in fewer moves than those above.
