Comb through a World War II–era codebreaking machine’s archive of books in TR-49, a gripping alternate-history puzzler from the makers of mobile classics 80 Days and Overboard! Guided by a mysterious voice, you’ll play unwitting detective—deducing codes, matching them to book titles, and tracing their stories through the past...and maybe the future.

What we love: Reading the preserved documents. While searching the archive, you’ll find everything from amusing family dramas (with convincingly exasperated voice-acting) to deep contemplations on the nature of oppression, violence, and the way AI can change a narrative. Keep an eye out for the cringey-but-hilarious Rampage series!

Quick tip: Each code consists of the author’s initials and two reference numbers, but finding them isn’t straightforward. Pay close attention to publication dates, deaths, and any authors who have changed their names.

Meet the creator: While crafting TR-49, three-person UK indie studio inkle was inspired by the WWII codebreakers of Bletchley Park. “What if an old computer, like the ones Turing built, had been left running?” narrative director Jon Ingold told us. “What might it have discovered?”
