Some websites have similar jackpot like this.
IMO, this kind of jackpot more profitable to a user who can be using a bot transaction every time someone deposits/buying the tickets then the bot will react to buying the ticket too. It makes him become the last person who buying the share, now the question how you can handle this kind of activity. I mean this is not really fair who someone who buying a share/jackpot by manually.
Cause of that is, I more like it a jackpot using a random generate random from the smart contract to determine the winners.
Which website do you refer to ? ( other than fomo3d )
I understand, but their is not much we can do, it is about the game design it self, we don't have much options here.
For early levels bots have no interest but they could have one if the games goes into very late stages.
The problem with using a bot is ( from a game theory perspective ) you need to be the only one doing so because if 2 players use bots it doesn't work for neither of thoses players. So maybe we can't count on the fact players will not try bot just in case some one else could do it and it would ruin the whole strategy.
Also even if only one player use a bot he can't know where the game session is gonna end he can only make sure game session not gonna end if is not the winner so if you use a bot you expose yourself to bet a huge amount without being sure to win ( except with an infinite amount of money of course ).
