If you lose with paper (they played scissors), they’ll play with scissors again next turn. As a counter move, you you should go with rock. While it may not guarantee your success, it increases your chances of winning.

You should observe your opponent’s hands when playing.
Aside from patterns, observing your opponent’s hand before they launch can also indicate what they’ll throw. Often, a loose hand ends up as paper. If two fingers are loose, it may hint towards scissors. Meanwhile, a tight hand most likely ends in a rock.
