But the several gameweeks I have seen this game being played, I think everyone plays to show they know what they are doing lol but this wouldnt be a bad strategy

Oh and winning back to back isn't easy because it's very competitive with more players jumping in every game week.

Yeah, even i never join the game, but I always following the growing number of participants every week. I know, for now with increasing number of participants, it be difficult to win back to back. However, my main concern is, about @tabas posts
"share the rewards with same amount of identical prediction if they win" this can bring some disadvantage among participants (even though the decision is 100% up to the Vega team and the manager). because even not 100% true, identical predictions with 100% same in answer, can suspect the possibility of cheating by several participants.
Therefore, maintaining the current rule that the first to submit is considered the winner is the right rules for me and maybe another will agree. As discussed earlier
This is because the following principle applies:
In case of tie breaker, earliest entry wins.
if you predict the first and your prediction is right, you are the winner. 2nd, 3rd users with same prediction will be out as winner

this is the easy way to keep the event fair. in the end, this is not just a pedictions only, but also a race.
