At what age did you first solve a sliding puzzle ?

[BeNotDeceived]

For the purposes of this poll you can choose up to three numbers. One for yourself, and two others such as friends or family members. This is for 2 dimensional sliders, typically with 15 numbers and 16 slots. Also, never forget your children

I was three, but you didn't have that option, so I picked four. I don't know when anyone else has solved one since I have never thought to ask.
