I just ran this with some frame adjustments as part of a Tyranny of Dragons campaign (this was a sidequest in Luskan with this temple being dropped in the ruins of Illusk), it worked great, and was a nice palate cleanser after many game sessions of heavy combat. As noted in the other reviews, these puzzles are of certain types that might not work well for every group, but they worked very well for mine. Just make sure you have a way of showing ALL the players the relevant imagery (I used Discord to share images as well as a single sheet for each puzzle image). Clear imagery for the card puzzle is particularly important to tell between suits of cards. My group is full of puzzle-minded folks, so none of these stumped them for very long. I only had to give the briefest of hints twice. I amped up the baddies at the end for my own purposes and it all came together.

So, don't be afraid to just use the puzzles in sequence for whatever purpose you need as they all work very well together and then up the CRs of monsters that you encounter to challenge your players at whatever level they are at. The introduction to Puzzling Temple encourages DM to use this material creatively and I applaud them for that.

My group played through this and had an amazing time. My players loved all of the different puzzles and didn't struggle substantially with any of them. Toward the end they guessed the big reveal but in some ways that was even more fun! This module was also very low prep for me as a DM- it's well laid out and easy to follow.

As another commenter mentioned the puzzles are mostly English word play. The adventure is also completely linear. If any of those things are likely to be issues for your players this may not be the right module. I also found that this module was particularly great for a few new players who love puzzles but were feeling intimidated by DND.

Overall run time for my group was about 5 hours (4 players at level 3- the twilight cleric loved getting to use turn undead at the end!)

The adventure has a very interesting proposal, but unfortunately for me it will not work. Almost all of the adventure's puzzles are based on wordplay and letters, which in this case are all in English. Although I am fluent in English, my native language and that of my group is not English, and many in my group do not understand English. So I can't use this adventure with them. And the puzzles have very specific with wordplays, which makes it difficult to adapt them to other languages. I tried. I know this is a very specific review, but like me there must be other people who speak other languages who might want to buy this adventure, so be warned.

I was very lucky to play through a very early version of most of these puzzles. I am not great at puzzles however I had a great time and it took five of us a while to make it though. I think if you have a low combat expecting party it is a lot of fun. You maybe get to run different characters than you normally would. This is a lot of fun for a lot of people and a great switch up for a party that is maybe needing a break from a dungeon or just wants a game with some super well thought-out puzzles. The clues are a great addition to this so you don't have an all or nothing expirience. That is a smart addition to this adventure.
