Prominence Poker

If you wish to not boost this and get it by playing normally, I think it's important to remark that you will get +1% on the progress towards the 100% every time all of the following conditions are met in a given hand, which means you don't need to have a better hand than every other player at the table and/or be the only big winner of a showdown:

-you need to participate all the way till the end of the hand
-someone else needs to get busted (drop table stack to 0 chips)
-your hand needs to beat someone elses hand, giving you credit for winning main pot / side pot 1 /side pot 2, etc, whichever pot for whichever amount of chips you beat that other player, doesn't matter if it's 2 chips or more, at the end of the showdown.

Example:

Player A goes all in with 80 chips, hand is A A
Player B calls and goes all in with 80 chips, hand is K K
Player C calls and goes all in with 80 chips, hand is Q Q
You call 80 chips and raise 20 chips more, hand is J J
Player D calls 100 chips and still has remaining chips, hand is 2 2

What happens in this scenario is
-Player A wins the main pot of 80 x 5 = 400 chips
-Player B gets busted
-Player C gets busted
-Player D just loses 100 chips
-You lose to Player A, but beat Player D and win pot of 20 x 2 = 40 chips

Result:
Both Player A and you get awarded with +2% progress towards 100% for busting Player B and Player C; that's 1% for each player whose table chip count dropped to 0, even though your hand did not beat all of theirs directly.

Knowing this, may encourage you to always increase the pot at least by the minimum amount everytime 3 or more people are playing a hand and at least 1 has gone all in hence has a chance of getting busted,

Hope this helps. Let me know in the comments if you have a suggestion to improve my solution.

This can be easily boosted in private matches. Preferably in 100 chip games to allow you to buy back in to your hearts content.
