If you’ve got some downtime at work, why don’t you try doing a jigsaw puzzle online?
Smartkit calls themselves a “puzzle playground” and rightly so.
You can choose from a variety of puzzles to put together and four different dimensions of each. The larger you go, the more pieces you’ll have to work with.
Once you start, you can change the color of the background and you can show the full size picture for a little help. There’s also a timer on the page so you know how much time you’ve wasted so far.
