Like solving mysteries and playing games? The folks at Puzzah! have created a FREE Urban Treasure Hunt that anyone (even the kiddos) can play and earn prizes. Here’s how it works: Come to the LoDo store between 11 a.m. and 8 p.m. to pick up a treasure hunt packet. Then visit six locations in Denver (including the Denver Mint and Millennium Bridge, learn about the history of each monument and fill in different codes. You return to Puzzah! and use the codes to open up six different boxes to get prizes such as mini puzzles and fortune cookies filled with Brain Teasers. The Urban Treasure Hunt will be ongoing through the year. Puzzah! is part of the new trend of “puzzle rooms” where a group of people enter an interactive game space and try to solve a mystery within a specific amount of time (such as one hour). 1440 Blake St. #150 (20 seconds from the 16th St. Mall), Denver.
