OpenKart - A solid racing game foundation


OpenKart (Formally Bloxy Kart) is a racing game built to be reliable and have little to no issues.

As of October 16, 2022, Bloxy Kart has been rebranded to OpenKart, and developers of all kinds can help contribute to Bloxy Kart, or even take OpenKart for themselves and make a new racing game!

Learning how the game works should be very easy. I made it very organized.

Found this game a bit ago, so wanted to make a kart racing game, and now look at this lol


Sad to hear that it’s discontinued but take care as always! was used to play this game but thank you, i’ll also try learning from the source code or maybe remaking this.


This is absolutely depressing and great to see at the same time.
@BillB1ox :sparkler: Don’t give up yet, success is standing back up when facing failures, the courage to be brave when upon fear and the effort to push through the numerous obstacles!

Who haven’t restarted a project before? Who haven’t changed their idea? Who haven’t faced difficulties? But where all still here, some with money, some with fame, but most importantly, with a undefeated and courageous heart!

If you do pick to leave however, it is your choice, but remember that, we will carry on with our dreams on Roblox, and you’re always welcomed to return :slight_smile:


Sad to hear that you have decided to go. Roblox is probably going somewhere bad, but there’s a chance the people at Roblox can get their crap together.

Farewell, my friend.

On another note, I am excited to see what you guys will do with this! Please notify me if you have done anything with this, I would like to play it!


Very sad to hear that this is the end for bloxy kart…

It was a fun experience, but, that’s how it ends?

Anyways, it was nice knowing you, and also enjoying Bloxy Kart was a unique experience.


Unfortunately, Roblox doesn’t do anything for their small creators, I actually almost got into Metaverse Champions but my game was not popular enough…

Can’t wait to see what you will do with it!

I hope i can bring the game to success somehow


That’s just life! Happens everywhere, the society doesn’t do much either for little entrepreneurs either.

You’ve spent a good effort on the game, and that’s what got you experiences, and you could honestly use them very well if you reform a new project.


I might come back when Roblox finally makes Studio native on Apple Silicon.

It is officially the only app on my Mac that is still Intel.

I’ll work on my project so it hopefully profits enough for me to purchase a basic windows pc, the 14-inch Mac is great and all but getting old and buggy plus with many limitations.
I guess that’s one of my motivations.

As an M2 Mac User I share in your frustration. Roblox is unfortunately really slow at getting anything done. They are the only intel app I use, literally everything else has been updated.

Sadly i found some bugs.

This one is very big as it legit breaks full match making.

Stuck on the loadingsreen for singleplayer for 10 minutes

You probably accidentally deleted files in replicated storage.

I’m not sure i did.


Infinite loading looks like the place was either not prepared correctly or that you don’t have the correct ID’s in ReplicatedStorage > BloxyKartService.

The BuildModeMatches file in ReplicatedStorage is simply a relic to Build Mode from the real Bloxy Kart. I believe that I forgot to remove something in StarterGui.

Seems awesome so far! Keep up the great work.

Bloxy Kart v4.5 recently finished development. Would you like an OpenKart v4.5, or are you fine with v4.4? Please note not all features of Bloxy Kart will be added to OpenKart just like the initial version of OpenKart.

  • Keep OpenKart v4.4
  • Make OpenKart v4.5
