Having a small custom Begriddled puzzle included on a flyer or other promotional material increases the average length of time people have that material in front of their eyes.

Even if they don’t try to solve it, the extra look can stop it going straight into the recycling box.

While they ponder it, your message remains in their sight.

If they look up the solution online, via a short url such as pzl.one/wmk, along with the puzzle solution you can show them more, and / or direct them to your website. Or put the solution on your own site so they go straight there.
