How do I send "3 extra moves" to a friend?

Joseph-3

I would like to send the gift of "3 extra moves" to my friends, but do not know how to do it.  BTW, I only play on my PC, not on a smart phone... does that make a difference somehow?

I only get the option to send to 8 of my friends who I know don't play anymore.   I want to send 3 extra moves to my friends who still play and who send them to me.
