This can be tough, but believe me it is doable. I have solved it hundreds of times and now can do it each and every try, 1st time.

But, let's make sure you have not made an error that is preventing you success:

- The most common mistake is setting the Gears (down below) incorrectly. They must be set (L - R) at 4, 3, 7. The common mistake is not realizing that you are STARTING at position 1, not position zero. So, to set gear on the LEFT to 4, you pull it down 3 clicks (because you are STARTING at position 1, three clicks moves you to position 4). Then move the center geat down 2 clicks to position 3. Then move the RIGHT gear down 6 clicks to position 7.

Below is the quickest path for getting all four crystals vibrating.

Here is the step-by-step fastest order for tuning the Spider Chair Crystals

RIGHT SLIDER to 4.
LEFT SLIDER to 6. (Timed portion doesn’t begin until you set the center slider.)
CENTER SLIDER to 12 up at the very top for an instant (don’t let go of the mouse button yet) then drag it down to 1.
LEFT SLIDER to 3.
RIGHT SLIDER past 7 (don’t let go), then down to 5.
CENTER SLIDER to 5 (center slider knob on a horizontal line with the right slider knob).
LEFT SLIDER TO 12 (go past 10 without stopping).
CENTER SLIDER TO 12.
RIGHT SLIDER TO 12.

Notice, you don't have to pause on any of the settings, just touch them and move on.

I'm glad that helped. Great to hear you are enjoying the game so much.
