There will always be people trying to get the loot of $100. That can be a lot of money for some, and if they are also able to do it with multiple accounts, then it is a nice snack. The Duelbits team will probably look into this thoroughly and easily catch cheaters and intervene if necessary.
Then can try but they will eventually be caught, Duelbits has maintained its status as one of the trusted gambling sites in the industry and they will not allow cheaters, as long as you are playing it cleanly and follow the TOS on Duelbits you will not encounter any issue it also applies on other trusted gambling site, a big gambling site like Duelbits will always play fair to all their players so players should do the same.
For sure there's an algorithm behind it because like you guys have said, 100$ is already huge money for some and I bet that they're ready for cases like this. Cheating isn't tolerated, of course, they are ready on it since they're a gambling platform and it might ruin their reputation if the platform has a lot of cheating cases. Maintaining the reputation of a platform is pretty hard, Duelbits have grinded that from the beginning so they won't let these kinds of cases happened.
Cheating is always there, it's just that they haven't caught it yet. they won't over-investigate with $100 giveaways unless they catch it by accident

are you sure each code is claimed by a different user ? I'm not sure because I think that if 250 codes are claimed there are at least 100 likes on the post
