For puzzle lovers, there’s a lot to enjoy in Project Iceworm. We really just found ourselves wishing that 21 Keys Escape Rooms would have built a puzzle that turned on the lights.

Project Iceworm, a covert 1960s venture by the US military, attempted to hide medium range nuclear missiles under the ice of Greenland. This was planned without the knowledge of the Kingdom of Denmark, of which Greenland is autonomous territory. The intent was to enable secret first strike capabilities against the Soviet Union.

The project was ultimately a failure and cancelled in 1966, its secrets lost beneath the ice… until now.

And yes, Project Iceworm was a real thing.

In-game: The entry way to the game, a restricted area with a lab beyond the door.


We entered Project Iceworm armed with flashlights or headlamps (our individual choice).

The gamespace was physically small, with an elegant wood and metal makeshift laboratory look. It had a unique aesthetic that was obscured a little too much by perpetual darkness.

In-game: Closeup of mounted box gloves for handling hazardous materials.


21 Keys Escape Rooms’ Project Iceworm was a standard escape room with a higher level of difficulty compared to other local games.

Core gameplay revolved around searching and puzzling.

➖ / ➕ Project Iceworm was unnecessarily dark. We wished we could have solved something that would have turned on the lights. That said, 21 Keys Escape Rooms provided headlamps, so we all had hands-free flashlights that illuminated whatever we were working on. This lighting situation, however, bumped awkwardly against a particular search puzzle.

➕ Project Iceworm was a puzzle-driven escape room. It had solid, layered puzzles with satisfying solves. These puzzles rewarded persistence, in a good way.

➖ Much of the clue structure was on laminated paper. Although this worked for the game, we would have liked the cluing to be more fully integrated into the gamespace.

➕ 21 Keys Escape Rooms built an interesting dexterity contraption into this game. It was a fun puzzle and we appreciated the extraction. It was unexpected.

➖ Project Iceworm was grounded in a story, but the story didn’t play a role in the escape room. Our experience didn’t have an introduction, conclusion, or dramatic event. The overall experience felt one-note and too emotionally level.

➕ The set was small, but it looked good.
