Give it a try, if you get stuck, I'll send you a video of the solution

So I guess no real tricks were required since you didn't list them. I won with a bot bump and a slider mount. R didn't like playing the game (walking around the outside) which caused a restart each time. The bot mount was also very tricky to keep R attached but also get B up. I'd prefer to see more reliable moves.

I have won without using the ball.

Yes it looks like there are several ways to win. I forgot to close it

@Shan14 can you please post the video solution. I'm stuck.

That's the way I mean

@Shan14 -

Since a trick was required in your intended way and you didn't bother to follow your own words, I'm considering passing from here on. Disappointing....

@Meko Guy
Actually I don't really understand the name of the trick *
so may i ask you a favor first before uploading in this forum?

Simpler win.

Spoiler: Video

@ridgerunner yeah
