Categories: Flash, Free, Games, Online, Room Escape

Submachine 7 – The Core, the seventh installment in the most popular Room Escape series ever created, is live!

“The game starts in The Sanctuary but big machines have been build up and the great wall to the left has been destroyed.

You will soon find a portal gateway to the Winter Palace, which was build by Sir Henry o’Toole, the architect of the Lighthouse.

The garden of the palace strangely resembles the structure of the Subnet…”

Have fun!

  5. mgb says:

    Ahh got past the Show

  6. mgb says:

    I haveShow

    now stuck

  7. White Wolf says:

    Found most of the keys and have found most of the ladders. Should be over half way through. At a loss right at the moment. Three key stones and that fit 30 keyholes. LOL

  8. mgb says:

    Actually I have Show

  9. mgb says:

    maybe the code Show

    don’t know what to do now…

  10. White Wolf says:

    Out with 3 of 5 secrets.
    Three tokens. So I’ll have to go back in later.
    Had to use the ingame walkthrough for the key stones. Found a hint but didn’t understand it. Maybe on the second round I’ll figure it out.

  11. mgb says:

    Out :) another nice game

  12. mgb says:

    For the 3 keystone/30 keyhole puzzle Show

  13. otacsof says:

    Wow, that guy is a amazing! It would be a million years before I came up with anything close to his games. I don’t waste my time with anyone elses games.

  14. White Wolf says:

    A text walkthrough will take all day. I will work on it but I’m sure you will get through it without one.

    Walkthough Part 1












    I have a ten page honey do list today so I’ll have to come back to this when I can. This will give you a good start.

    • DNOMN8R says:

      Thanks – I’d been totally stuck.

      Good luck on that honey-do list…I’ve got a hunch you’ll need it. [insert emoticon here]

    • White Wolf says:

      OK.. I got the honey do list done! LOL

      Walkthrough Part 2








      I still can’t find the other two secrets. I know I’m close, I just can’t find them. There are two places I couldn’t get to. I’m sure someone will find them and let me know.

      The game auto saves so you can go back to it and try different things. This will at least get you out. You’ll need to learn the rest. I will add a link to the picture of the symbols if you can’t figure them out.
      Good luck!

  16. White Wolf says:

    5 of 5 secrets!
    It’s late.. I’ll let you all know were tomorrow.

  17. White Wolf says:

    For all 5 secrets you need the tokens..

    1. Show

    2. Show

    3. Show

    4. Show

    5. Show

    Use maps next to the arches and picture hint to find Symbols and their order needed to call the cable car.

    Symbols and Positions 3 and 1 on control box


    Symbol and Position 2 on control box


    Symbol and Position 4 on control box


    Symbol and Position 5 on control box


    OK.. That should do it. Out with all five secrets.
    Good luck!

      What to do with the tokens:

      • White Wolf says:

        OK.. I was in that pipe but couldn’t find the target portal. I was wondering what people were talking about using the coins. I tried and couldn’t get any farther into the pipe.

        I found the place to put the light bulb on the first round of play and knew something else had to go in there. I was looking for another light bulb. LOL

        The portal is so dark I couldn’t see it. Like the hole were you put the glowing box. My flat screen sits at an angle that I can’t see anything on the upper part unless I stand up.

        Thanks to the author for the background on the game development. I like behind the scene peeks.

    the tokens you get from secrets are used in the secret lab area.

  20. Darkstar says:

    This one, was really Hard

  21. Em says:

    Yeah!! A new submachine!!

  22. Em says:

    I got a different ending from white wolf, I clicked on a green portal after I climbed up the ladder in the cable car.

  23. Em says:

    It has to be more..what to do with the glowing box??!

    • meow :3 says:

      i feel the same way, like there’s more to the game I’m missing or something. what do we do with the glowing box? how do we use the secrets? is this all of the game?

      • NurseGrenade says:

        Just like the other games by Mr. Skutnik (I’m talking about Daymare and Covert Front, too), this one leaves cliffhangers to add suspense and such. Not to mention it leaves you wondering “Whoa, what’ll happen next?“

  24. mimi says:

    I don’t know how put the symbols in control box
    can u help me?
