A mistake with one blue ball cost 5.75 million yuan. The second prize of the Double Color Ball won this time by "Ink-stained Cloud" was hit using a back-number betting method. From the order screenshot, it can be seen that his numbers accurately hit all six red balls of this issue's Double Color Ball draw. However, the blue ball he selected was "15", while the blue ball for this issue was "11". Thus, "Ink-stained Cloud" very regrettably missed out on the grand prize of 5.75 million yuan for this issue.
It is worth noting that "Ink-stained Cloud" only registered as a NetEase Lottery user on January 30, 2012. Just 22 days later, this lucky user won a 61,066 yuan prize at the lowest cost. The story of winning a big prize shortly after registration has been played out multiple times on NetEase Lottery.
Link: What is back-number betting?
Back-number betting refers to placing a bet on one or a set of numbers for two or more consecutive draws. Back-number betting can be divided into continuous and intermittent types. Continuous back-number betting means the draws are consecutive, while intermittent back-number betting means the draws are not consecutive. For example, if you choose one set of betting numbers and decide to buy them for five consecutive draws, you just need to pay a 10 yuan advance payment, and the system will automatically place bets for you in each draw.
