1 / 2303 Escape - Denver Escape Room
📍 Thornton, CO
303 Escape runs two chapters of a continuous horror-themed storyline set in the Blackmore Hotel. All rooms are fully private — no stranger pairings ever. Hollywood-level set design, lighting, and audio.
303 Escape had a great puzzle room. We did part2. We enjoyed and it and the main host had a personality that was a perfect match for the story line. Thanks for making it memorable and sorry we couldn’t save you this time. We’ll be back one day!
🏆 Family Action Verdict
Best for families with teenagers aged 13 and up who enjoy horror-adjacent puzzle challenges. The content — serial killer narrative, torture chamber references — is too intense for younger children. Teen and adult groups thrive here. The private booking model makes it excellent for family bonding without strangers in the room.

“Family of 7 from 13-55 yo. We all loved it. We died, but it was a ton of fun. Difficult for sure; we only got 70% through it. We will be back! Highly recommend.”

“My boyfriend and I did both rooms at 303 Escape and we loved both of them! We had a great experience both of the times we have visited. When you walk in through the door, it feels like you're in an actual hotel. Derek, who was our host for part 1, was also phenomenal! He was very helpful and stayed in character which really helped contribute to the ambiance of the escape room. The puzzles themselves are well thought out and the technical design is all very cool. We're really looking forward to the release of part 3 so we can go back!”
