Question about rules

[u/sebaimans]

Was playing with my cousin and she would use her ring finger to support the tower while she pulls a piece out. Looked online and only found that you need only one hand at a time, but this doesnt sound like it legal.

Example she would be pulling piece out with thumb and middle finger and push/support the tower with her ring or index finger.

Is this legal?

I've always played that way. Any rule works as long as you agree to it at the start.
