(V3.2) solutions to all levels in worlds 1 to 11.

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 v3.2. 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 v3.1 of graBLOX, MobilityWare’s recommended number of moves was too big for levels 9-24, 10-7, 10-9 and 10-25; this has now been fixed in v3.2, but I can now beat their recommended number of moves in level 11-11 ;-)

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. For world 11 I’ll need to find the time to implement how the new block “pushy” works before I can say anything about optimality of solutions.
