You don’t have to spend a few hours on it, because theoretically you can win by just offering random options. How many slots are there on duelbits? For example, generate a number from 1 to 1,000 on random.org’s website and try to find that slot. If the slot does not have a suitable color range from the picture, then generate a new number and so on. The first suitable random slot can be sent as an answer variant. According to my observations, the slot is guessed on the second or third day, so we have at least three chances. If you take the total number of slots, subtract those that don’t fit the color scheme, you get a number of possibilities. All we have to do is take a few of them and send them as a possible response. The odds of winning are much higher than in lottery and free participation. Just thinking in theory. Maybe someone will win 200$ if there are 90 rounds offer as an answer only Sweet Bonanza.
