Joss sticks with numbers

My mother-in-law bought a lot of new joss sticks for praying during Chinese New Year. I'm not a religious person and i dont pray much. Come to think of it, i've been living here for the past 8 years or so and i cant even remember when was the last time i lit a joss stick at the altar. Maybe i've not met my calling yet. Since we're on the subject of joss sticks, have you seen those that will a produce four numbers at the top few inches for people who loves to bet on numbers when lit?

My brother bought some before Chinese New Year for our late father's 49th day prayers. I wonder if he bet on those numbers or not. I didnt. If i did, maybe i would have won some money, lol. I can then go to Las Vegas for a holiday during Chinese New Year since i cant celebrate.
