I received a bonus from a bookmaker

I received a bonus from a bookmaker, but I don’t understand what to do with it and how to use it correctly for betting. Can someone explain it in simple terms?

I was also stunned at first when the bonus arrived, and what next was unclear. I simply opened the promotions and terms section; everything was laid out there without any complicated language. The page 1xbetonlinepk.com/promo was especially helpful. After that, it became clear that the bonus wasn't a separate payment, but an addition to my bets. I started with individual football matches to avoid confusion. After a couple of days, everything fell into place.
