Project Spark

It is now possible to do this by yourself, all you need is a second gamertag, doesn't even have to have Gold membership.

Upload a world on your main tag, log out and into your second tag, remix the world 10 times, making sure to Save + Share, make it visible to be on the safe side.

Log out and back into your main tag.

Achievement unlocked.

After months of trying to figure out how to get this achievement completed, I finally figured out how to get it. You have to have 10 copies of your world published at the same time. What I ended up doing was creating 4 new gamer tags, and have them remix and save/share that world 3 times per gamer tag. Once you have 10 copies of that world actively being shared, your achievement should pop up (took about 5 minutes for me) after you log back in with your main account.

PS you can only create 3 new outlook accounts per day.

With the server shutdown this achievement is now unobtainable.


The other guides are great, but this is mainly for the people that have more than 10 remixes and still don't have the achievement. If you have that problem then skip to the bottom. The first part is to explain for anyone just starting.

Creating the remixes

First of all, this is best done with a second account (Gold or Silver membership) or a friend that is online at the same time you can communicate with. Have your friend/second account find the world you want remixed and click "Remix." From there follow the below:

1. Press
2. Save
3. Save + Share
4. Place in a new slot
5. Make it Visible to all
6. Exit the world

Repeat the process until there are 10 remixed worlds uploaded at the same time. Log in to your main account, or restart the game when your friend says they've done it, and the servers should update and pop the achievement. If not, refer to the below section.

Fixing the remix glitch

I only found this because I had 25 remixed worlds active and only 10% progress. The tracker will only improve if the lineage tab has your world with the creator or co-creator label on it. In my case, the lineage glitched and said "UGC Error." I could earn rewards from the remix, but not the achievement. Just verify that all worlds that are remixed have your account as the next world in the lineage chain and it should pop without a problem. If you find a world that results in the UGC error when remixed, then remix another world on your main account and try it with that one.

Out of courtesy, delete these remixes when you're done so you don't clutter up the feed for those trying to get Rising Star or also want Catalyst. It's also a good way to have your upload privileges revoked, if Team Dakota still enforces that.

If this fixed your progress please leave a comment! I want to make sure this works for people. Hopefully it helps someone.

The solutions already posted have the right idea, but I thought I'd spell out the steps a little more clearly.

1) First, with your main account, create any world. This can be an unchanged remix of an existing world. It does not matter.

2) Now, with your second account, log in to Spark and choose, "Play."

3) Search for your created world, and select "Remix." (You don't have to play it.)

4) Hit the menu button and select Save -> Save As, then change the name slightly. I added "remix 1" to my first remix.

5) Once it saves, select Save-> Save+Share.

6) The game will ask you to select one of 100 save slots. Select "New Slot."

7) The game will ask you if you want the world to be visible. Select "Visible."

8) Once it saves again, select "Exit." You should be back on the info page for the original world. You can repeat steps 3-8 nine more times, then log back in with your first account and the achievement should pop shortly!

To check your progress, go to the info page for your originally created world and tab down to "Lineage." you need the 10 remixes to show up down there. This should only take about 30 minutes, tops.
