Doing a 7/7 is a very unique thing, it didn't happen as far as we know for the past 2 seasons and now in this season we had like 2 very quickly if I am not wrong, then it stopped again as far as I am aware. People expected it to continue for some reason but it was very unique and just because it happened this year doesn't mean that it will keep going on.
I feel like something bigger could happen, as I have always said there are other big leagues in the world, bundesliga, la liga, ligue 1, serie a all have a big place in the football betting world and I think if we could contribute them as well, we could do 5/5 and 25/25 different bets, where people who have 20+ rights will earn something and if anyone has 5/5 from any league they win a smaller prize as well, and anyone who gets 25/25 would get a huge reward. 5 games, 5 scorers from each of the 5 leagues. Sounds amazing to be fair.
Considering how rare it is to see 7/7 already, seeing 5/5 would be a lot more common and there could be a smaller, way smaller reward for that but if 7/7 is already this rare, then 25/25 will be near impossible. In fact, I am pretty sure that it is VERY rare that we had 25 games in a single week where every team scored at least 1 goal.
It is obvious that most of the time there is at least one 0-0 game and that means it would be quite near impossible to win it. Not only there needs to be at least one goal in all of 25 games, but you would also have to know who scored on that week as well. That is like a 10+ bitcoin win type of rarity, it would happen maybe once every few years, probably not even that much.
I'm not hoping much but who knows that blind selection will give me something
