REA Reaction

The Puzzle Effect’s The Path was a solid take on a traditional escape room format. This room was all about the puzzles, and a wide variety of escape room puzzle types were represented. A few puzzles had nice tie-ins to the subject matter presented, including zodiac animals and a small collection of Chinese artifacts.

In contrast to The Puzzle Effect’s other rooms, The Path had zero combination locks. As our team played The Path after some of The Puzzle Effect’s more lock-heavy rooms, this was a breath of fresh air.

The Path would be a great option to sell newer players on the concept of escape rooms. While The Path provided less novelty for more experienced players, its smooth, straightforward puzzle flow could be enjoyed by all, and it was a serene environment in which to spend up to an hour.

A dojo-like environment, with a strong east-Asian aesthetic.

REA Reaction

Grim Stacks was the kind of Harry Potter-inspired game that we wanted to explore. It stood on its own, but its allusions made fans feel at home.

The bookstore setting was really smart because the Puzzle Effect was able to completely sell it as a real environment.


From a gameplay standpoint, this was a solid, well-themed game. We enjoyed it quite a bit.

We would have loved to see a little more drama from the finale. It was a super crafty conclusion that was a sub-woofer away from greatness.

If you’re in Denver and a fan of J.K. Rowling-esque magical fantasy, go visit Grim Stacks.

Who is this for?

  • Harry Potter fans
  • Puzzle lovers
  • Any experience level (but it will be hard for true newbies)

Why play?

  • An adorable setting
  • Challenging puzzles
  • A clever ending


The nefarious owner of a magic book shop had captured a powerful creature and locked it away. The magical beast needed rescuing before it was forced to do evil deeds.



Grim Stacks was a charming twist on the Harry Potter-esque escape game. Instead of placing us within a wizarding school, we found ourselves in a magical book shop. That was smart because it was easy to sell us on this world.

The first act of this experience looked great. The second act was a bit of a step down. It absolutely worked, but it didn’t quite feel as thoroughly designed.



The Puzzle Effect’s Grim Stacks was a standard escape room with a moderate level of difficulty.

Core gameplay revolved around observing, making connections, and puzzling.



βž• Grim Stacks looked great. It was magical, in an adorable, nerdy way. It was a bookshop, after all. It was an approachable and inviting space to puzzle in.

βž• The game flowed well.

βž– Some of the cluing was presented on laminated papers. There was an opportunity to better integrate these components into the game world.

βž• The puzzles had depth. They were layered solves. We appreciated puzzles that we could really sink our teeth into.

βž•/ βž– The ending was clever. It provided a conclusion that made sense in the game world, while leaving the heavy lifting to the players’ imaginations. That said, there was opportunity to go bigger, adding bolder visual cues and auditory effects, without changing the concept or blowing out the budget.

Tips For Visiting

  • There is a parking lot.
  • The Puzzle Effect offers this game in other cities as well including Bakersfield, San Luis Obispo, Phoenix, and Boise. The opening scene is slightly different in these locations, but the gameplay is the same.
