|Many themed puzzles keep the idea fresh.|
To keep things fresh, JigZone has a puzzle of the day and also a custom puzzle feature that I haven't tried out yet. Underneath the puzzle space is some statistics about how long you have taken compared to the average and the fastest time - I plan to introduce these to my students as they progress.

They have some ads on the puzzle page. The top ad is an unobtrusive banner but the bottom ad is a square video which autoplays and enlarges to a full-screen video advert when you mouse over it. For my young (and even older) students this is a huge temptation to play with. We constantly do talks about the purpose of advertising and remind our kids about our limited bandwidth, which means running a full-sized video ad is not the best idea.
Despite the adverts, JigZone offers a great puzzling experience for my students.
