  1. Think 3D, people.

  2. g in the y

  3. Hmm, that’s tricky. I thought I was on a roll but it seems I’m not as great of a genius as I thought.

    PS-Recaptcha is “be Barney”…my life goal? :)

  4. Couldn’t you move a quarter from your pocket to the end of the horizontal row?

  5. Move the quarter from the bottom up one space to on top of the quarter where the vertical and horizontal rows intersect.

  6. Sorry folks made a little error. You have to move the top quarter down to where they intersect…

  7. these brain games are starting make me cry! the answer is almost always so aargh…I don’t know a better word in English to describe it!

    @Nick…liked that!

  8. I’m with Nick (and never would have got that one on my own) – it doesn’t say where the moved quarter comes from.

    The solution shown falls short – it only gives two intersecting rows of three quarters each, plus one row of two in the vertical axis.

    (is that 3D enough for you, Ira?) ;)

  9. yay! first one i actually got. and within 10 seconds. the previous ones have been arggh-material.
