hey guys! I'm back with an interesting puzzle. It's shown on a Mondo Magic Singapore, so i thought u guys might be interested in it =)

ok so here's the puzzle:
Notice that all columns and rows add up to haf 10 dots each. As seen, each column consist of 4 boxes, each having different number of red dots. So here's what i want you to do:
1) Remove 1 dot from any of the boxes containing 2 or 3 red dots. Notice that when u remove it, the sum of all boxes in that column/row decrease by 1, i.e. No. of dots=9.
2) Now, move 1 red dot from any box containing 2 or 3 dots on the adjacent rows/columns to the corner box (i.e. the box that contains 1 or 4 dots)
3) Sum up the number of red dots in each row/column. Is it still 10?

It should be still 10 =D Amazed?! Dun be amazed yet. Try repeating step 1 to step 3, and be amazed again!! Try it out! Use a pen to draw the dots or any objects to act as a dot. Take some time of mugging and marvel at this puzzle. Do you believe in magic? =D

P.S. I was amazed at first. But after some pondering, i realised the mathematical application to this puzzle. So, think about it and take a break from all the mugging! Ur brain cells need refreshment by working on such interesting puzzles ;)
