I am desperate to get the solutions.

If you have the solution there is no point in playing the game!

Which level(s) are you having trouble with?

I am having trouble with levels 79 and 111. I beg to differ from RINDI. I am a school teacher, and I encourage my students to solve this game. They are very interested in it.  Only these TWO levels  out of 180  alone pose problem.   I shall be grateful for the solution.

Sir, While I am grateful for your suggestion, I seek your indulgence to state that I have reached the position shown in the picture.  My problem is to get into the   enclosure where there are three  boulders - two at the top and one at the bottom-are placed in an inaccessible position.  I need your help.  Rgarda.

This should help with that, apologies that the bulldozer doesn't always do anything (that's when I was trying to remember how to clear the area!)

I hope you understand I'm trying to help by solving parts of the puzzle so that you can learn from this too :)

Sir,   I remain ever grateful to you for your help.    With your guidance, I could move the boulders in Eastern side into the enclosure.   But, I am unable to get back to the North Western corner to move boulders.  Which ever I move I get blocked.   Could you guide, please.  With sincerest wishers and warmest regards, yours sincerely, r sundararaj  

This is about path preparation before starting the clearance of the top-right (NorthEast) of the puzzle.

Can you share a screenshot of the point you realise you're stuck with the path back?

Sir, As you instructed, I have sent two screenshots for your viewing. Please help with the next step to cross over to the northeastern corner of the game board. I am grateful for your efforts and time. Regards.

Sir, I am sorry for the mistake.  Please help with the next step to cross over to the NORTH WESTERN corner of the game board. I am grateful for your efforts and time. Regards.

Aim for this arrangement:

Sir,   My students and I are at a loss for words to convey our grateful appreciation of your efforts and time. Our six-month-long struggle ended today, thanks to you. Our computer expert is examining how to store critical positions at each level  for guidance in the future.  In our opinion, BULLDOZER (push the boulders) is as best as the Rubik Cube and its variations. It is an excellent test for thinking out of the box.  May the GOD Almighty shower HIS Blessings in abundance upon you and upon all the members in your home under your care, ensuring excellent HEALTH, unfathomable WEALTH, and unblemished SUCCESSES in all your endeavors to all of you in all the times to come. With our sincerest and most affectionate blessings to your children and grandchildren and with our sincerest wishes and warmest regards to your better half and to you,   Yours sincerely, r Sundara raj.
