The 13th Doll is a game created by and for fans of The 7th Guest series! It began as an all volunteer, freeware passion project, but evolved into a fully licensed game.

In the 7th Guest, evil toymaker Henry Stauf built a mansion, and invited 6 guests. A 7th Guest, Tad, snuck in and was trapped there, afflicted by mystifying spirits, dolls and the ghosts of the other guests - until he defeated Stauf.

The 13th Doll ties in with the events of The 7th Guest. A decade after Tad managed to escape the mansion, he is still haunted by the souls, dolls, and Stauf's victims he left behind. So haunted, in fact, that the young man now resides in a mental institution - misunderstood, plagued by guilt and obsessed with one idea: to escape the dreary padded walls of his asylum cell, return to the mansion - the site of his innermost fears - to rescue those he left behind and defeat Stauf once and for all!

Soon, a new doctor by the name of Richmond arrives in the asylum. Naïve to the legacy of Henry Stauf, and equally bewildered and intrigued by the fantastic legend, the staunch rationalist plans to take Tad on a cathartic trip back to the mansion.

This unconventional therapy attempt rapidly turns into a fateful journey, unravelling Tad and Richmond's contrasting worldviews and leading the unlikely duo straight into a horrifying vortex of lies, illusions, lunacy and death. And soon a blood-curdling question arises: Have the two visitors really made their way to Stauf's harrowing home on their own accord or are they mere pawns in a much grander, inescapable scheme?

While playing The 13th Doll, a lot of time will be spent navigating through gloomy sites, concealed rooms and maze areas from an immersive first person perspective. Thanks to the game being developed in Unity3d, this becomes an advanced and engaging experience, as the engine allows free movement and a fully accessible environment in detailed high-definition visuals. For the first time, players will be able to explore every inch of Stauf's residence and face all its eerie inhabitants up close and personal. A plethora of interactive, delightfully animated objects will bring even the most desolate locations to life.

Logic puzzles were an integral part of The 7th Guest's gameplay, and The 13th Doll follows suit. We've designed 26 original brain-teasers, all varying in style and offering a wide array of intellectual challenges. These diabolical creations are found throughout the game - whether it be card tricks, pathfinding and chess challenges, or even artificial intelligence puzzles versus Henry Stauf himself!.

Windows 7 is listed as a minimum computer spec at both GOG and Steam, so it should play, Ana. There isn't even a video card requirement listed.

Oops! I see the game developer has posted about the issue just before I posted this! Hopefully, they can get it worked out.

If your computer has good enough hardware, you might be able to just upgrade it to Windows 10.

Note: We know about some issues with Windows 7. Even though it isn't officially a supported OS, we're doing all we can to identify the cause and get things working!

I could have sworn it said Windows 7 on Steam too! Obviously I misread it!

We've identified at least one of the contributing factors to the black screen/game crash issues. It has to be fixed in quite a few areas in the code. We're working on it!

That being said, this is also caused sometimes when the appropriate Webm codecs aren't installed, as mentioned in the links earlier.

There's already somebody here in the hints and help forum looking for puzzle help.

That means we did it right!
