I checked again :roll:

The 4 x 4 matrix is formed by the co-ordinates 0,0 to 3,3. How can I draw it here? :(

I tried to plot it in excel. Please check the screen shot below:

Start from lower right corner of the 4x4 grid.

Correct! If you went out of the box(grid) you will get another solution! :)

Your solution crosses a line already drawn which is not permitted as stated in the very first connection puzzle. Try again ! :)

Let us move from squares to circles and balls! :)

A 40 cm diameter ball is on the floor touching a wall leaving a gap where the perpendicular wall joins the floor. Can a ball with 7 cm diameter pass through the gap (between the ball, the floor and the wall) ?

Radius of ball 20cm.

According to Pythagoras,
Distance between centre of ball and the edge of wall = 28.28 cm (sqrt(20^2+20^2)).
Of this 28.28cm, 20cm is already covered by the ball.

So a ball with diameter less than 8.28cm can pass through the gap.

Was a nice stress relief.

Oh! I didn't know that we shouldn't cross any line.. but then, with that constraint even the 9 dots puzzle has no solution.. right? :)

If a line goes through a dot it is not considered crossing a line. If it crosses between dots it is considered crossing a line! :) You could try something similar to the solution for 9 dot puzzle ! :)

8.28 cm is the distance between the large ball and the corner where the wall meets the floor. What is the distance between that corner and the largest smaller ball that can go into that gap? :)

I am sorry I dd not scroll back to see any solutions posted ! :)

I can't figure it out, unless I am allowed to retrace my path along one of the lines. Could you post the solution please?
