Lotteries are pretty much self-explanatory. You simply pick (or are given) a set of numbers and if your combination of numbers matches the drawn ones, you win!
Of course, there’s a little bit more to know about lotteries in general but the best way to learn is to dip your toes and just play. If you’re interested in trying out the lottery here, Play88 offers QQKeno — one of the most well-known lotteries in the world.
