Inventory bag tag on top right. Items are drag and drop to the bag slots.
I figured it out, I never saw it on the side of my screen as a little brown box. Thank you for the info and maybe the box could have a little message stating like inventory because I was so confused for several matches. Also a big fan of the first game that I got a new phone and redownloaded it just to beat it on the first match in about less than 10 mins. XD
