Love it but I need some guidance!! – Bubble Shooter - Fun Bubble Games Review

I love this game , I'm on level 167 and am getting thru the last few levels by trial and error, if anyone is playing could u please use this review Space to briefly explain to me what the little numbers in the bubbles mean , I feel really stupid asking for help, but I'm using up my lives and coins like crazy, thought I could do this on my own, I don't want to stop playing , Thank u so much to anyone that would be willing to take the time ❤️❤️ !!
