(V3.1) solutions to all levels in worlds 1 to 10.

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 v3.1. 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.

Level 1- 1: 1.d7
Level 1- 2: 1.a11 2.d7
Level 1- 3: 1.g7 2.f7
Level 1- 4: 1.f10 2.b7

Level 10-25: 1.b10 2.g9 3.a5 4.g3 5.a2 6.h6 (note: 6 moves)

Note that in v3.1 of graBLOX, MobilityWare’s recommended number of moves is too big for worlds 9-24, 10-7, 10-9 and 10-25. I am particularly proud of 9-24, which I can do in 13 and MobilityWare could only do in 15 ;-)

According to my computer program (which may have bugs!) the solutions above are minimal solutions to all the levels, other than 6-18 and 09-24 for which I’m not sure, because the levels are too complicated to solve by brute force.
