Spin the Black Circle. It’s tough, but I made it all the way through. There is a YouTube video of a walkthrough if you need it.
Only took me 5 minutes.
To realise that it was going to drive me crazy. So I did the brave thing and gave up.
Interesting concept.
This is awesome. I have no idea what level I’m on though.
That’s quite cool. No idea which level I’m on either though.
If you leave the site and then return, it will let you choose which level you want to play (up to the last one you attempted) and you can see how far you’ve gotten. I think there were 23 total.
Ah, that works. I’m stuck on level 12, that spikey spiral pattern.
Level 12:
I think the concept for this one is straightforward. You should maintain some momentum through the outer parts, but watch out for too much momentum when it gets tight in the middle or your ball will jump off the track.
Yeah, no kidding! :mad: 
Holy crap. If you think that level is hard, just wait until you reach the one with the red bouncy ramps. Spikes, fire, electricity, mid-air acrobatics… all kinds of bad.
Well, now I"m on 16. Crap! This is going to come down to luck.
I’m going to have to leave this one for tomorrow; I’ve spent 20 minutes on it going nowhere. :dubious:
Level 16 advice:
Tilt the wheel one notch counter-clockwise to get the ball rolling. Just as it leaves the platform, hold down the Right button to spin clockwise. This will come pretty close to the groove, but you may have to adjust a bit.
I made it to 17 last night, then got tired. Not sure if I’ve got the patience to go further, but it does make for a great way to blow off homework.
16 was rough but it seems you can control whether the ball free-falls in a clockwise or counter clockwise direction. If you do it right, you get the ball falling counter clockwise while moving the background clockwise.
17 is evil, though.
17 wasn’t too bad for me. Took about 4, maybe 5 tries tops (not including the one desperation attempt of going through the electric currnent, hoping it might forget to kill me).
What worked for me was not to roll across the paddles; the speed you need to make headway against the rotation will just send you off in to the spikes. Instead, I rolled off the platform at a decent speed and bounced off the paddle tips while slowly rotating CCW. Took two or three tries before I dropped neatly into the hole.
20 is the one I’m still stuck on. I’m almost afraid to pass it; the last 5 levels are sure to make this one seem like a cakewalk.
Ok, Maybe I’m being stupid - How do I actually begin playing the game? I can’t find a link to click on.
OK I found it. ‘Click here to play’ under a picture of something else entirely
