What I love about Artifact Puzzles is the unique cuts and whimsy pieces, the surprises that each puzzle holds, the discoveries! Cathedral of the Changing Tides was my birthday gift. Thirty six years before, a very special birthday gift arrived in the form of my third child, Daniel, who remarked when I opened the box and started sorting the pieces, “turtles!” Indeed, there were a lot of turtlish shaped pieces, which really made me wonder how on Earth they connected… Other whimsies included birds, a stork, fish, gargoyles… Gargoyles? Oh yeah, a cathedral needs a gargoyle or two. However, I don’t want to utterly spoil this for those who decide to go for it and discover this puzzle for themselves. Suffice it to say that it is unique, fun, challenging, with some interesting surprises. I didn’t time my efforts, but I suspect it took me a good 5 or 6 hours to put the whole thing together, but it will probably take me less time the next time that I do it. Of course, I didn’t look at the image, because I prefer to be challenged. I definitely found it to be fun, but more difficult than usual, because of the tricky shapes, and less obvious color differences. Also, you do have to be careful, because it is possible to do it wrong. Some pieces do fit together, even though they are the wrong ones, so you have to be sure the color lines match exactly. I wouldn’t advise this to be a first time Artifact puzzle choice. However, seasoned puzzlers, who collect them and love them, will definitely enjoy this one! It is also a beautiful image, with lovely colors!
