Chapter 1, The Lighthouse | Chapter 2, The Clock Tower. | Chapter 3, The Forge. | Chapter 4, The Observatory. | Chapter 5, The Projector, Imprisoned Ending. Release Ending | Escape Ending | Lost Ending

See my review for The Room Three.

Walkthrough:

Ending 4, Lost:

This is the final ending. If you’re missing any of the items needed, go back through my walkthroughs for the Release and Escape endings to find them.

You can also watch my video walkthrough for all three alternate endings here:

Go through the portal again and repeat everything up to the train door. Don’t go through.

This time, place the mysterious device on the right projector. But don’t turn it on yet. Look at the other side and find the screw. Use the screwdriver to unscrew it and slide the covering over to the right. Then, use your eyepiece to go inside and solve the laser puzzle to turn on the projector again like before. DO NOT GO THROUGH THE DOOR YET OR YOU WILL JUST GET THE RELEASE ENDING AGAIN.

Now, place the hexagonal mysterious device on the left projector and use the eyepiece to go inside and turn it on again. The door changes again. Go through to get the fourth and final ending, Lost.

    My game went blank while I was playing the first alternate ending and now I cannot back into the game at all. What can I do?

    1. AppUnwrapper

      I suggest emailing the developer or contacting them on social media. That sounds like a nasty bug.

    This shows how to get to the Lost (4th) game, but not how to get thru it?

    Thanks for the walkthroughs…I the alternate endings (3 of them) and this Game is nothing like I have ever seen…I wonder if any other Mobile Video Games can even boast of coming any closer to this one…Hope this saga continues…

      I loved The Room trilogy, but I found Forever Lost even better. There are 3 Forever Lost games plus a prequel called Alice’s Story. If you haven’t played them already you’re in for a treat. Enjoy!

    Thanks for your guide – my son and I play together and if we get stuck for too long it spoils the fun we have together. So thanks very much

    I love the game but I’m stuck on getting through the door with the beam of light on it. I have got the beam of light to go through centre but it doesn’t do anything. Thanks for your help

    I have completed 3 of the alternative endings. We are now stuck on lost. We used our hexagon object in the previous ending and the game has not /will not reset so we can aquire it again. We are getting very frustrated. We cannot advance without the object and cannot get it again. What can we do. My son is frustrated, I’m frustrated. At wits end. Please help if you can. These walk throughs have helped my 5yo navigate the alt endings and I hate to ser him this stuck.

      Did you try just restarting the chapter? That should give it to you…unless it’s a glitch.

    2. Davina

      I have restarted the chapter 3 times. It brings us back to the center room with the safe already on the floor and the fortune teller already decommissioned… Going nuts

      1. AppUnwrapper

        That’s really weird. I would recommend reaching out to the developer to see if it’s a bug. Maybe they can help.

      2. Sheena

        Having the same issue

  7. Maddy

    I finished the first 3 endings then went to change my fate to do this one, but when I did that it restarted my whole game from the tutorial. Very annoying and inconvenient.

    1. ueje

      you have to press change your fate

  8. Pamela Douglas

    Thanks to your help, I eventually finished, I had to play a couple of the endings twice as I seem to have mixed them up. The tracker ball was the hardest bit as it just wouldnΓÇÖt move, but got the hang of it in the end.

  9. Raylaena

    I’m trying to play the Lost ending and I’m seriously stuck on the lasers with the blue crystal….can’t seem to get them all aligned properly….

    Thank you thank you thank you!
    I was getting so darn frustrated about this stupid light going out for the fourth ending.
    I thought it was a bug.
    I simply forgot about this stupid screwdriver sleeping in my inventory even after thinking about it just a few minutes prior -.-

  11. Caitlin

    Hey, I’ve done everything exactly as you said in this walk-through 6 times and it only let’s me get the “Release” ending. I don’t think I’m doing anything wrong but this is extremely irrigating having to redo this over, and over again.
