[SOLVED] How to submit a bot to arena?

I’ve won simple training bots, and got a popup “please submit you bot to arena”, which I dismissed. Now, I’ve searched every link I could find, both in game page, and my profile, and elsewhere — the only mention of arena I can see is when I delete a training bot and press “+”, it says

Compare your AI with the following and push your bot to the arena to unlock new players.

So, how do I do that?

Sorry, I’m new here, and I imagine this be kind of FAQ, however from those and google I don’t see it documented.

Okay, nvm, I found a button Submit at “Actions” panel. Essentially, just search the browser for text “Submit” at the page with the game and you’ll see it.

Click the yellow “Submit” button at the bottom right.
