I am constantly trying to improve the poker client. I came up with an idea where if you didn't want to pay a fee to enter, you don't have to..

If you do, then you can win more:

Optional Buyin Upgrade:

Users will be given the option on All Tournaments with a buyin depending on the prize pool size. Let’s use the example of a 300,000 Coin Tournament

I will need a new option here to choose if this is an “Optional Buyin Game” http://prntscr.com/onlpc3

Users are given a choice when they enter a contest. They will be paid out a % of what (if) they win depending on how much they paid to enter the contest.
https://prnt.sc/ojjg2n when they register, they are presented with a popup that says:

Please Choose Your Buy In Amount:
XXXX Coins entry fee will give you 100% of whatever amount you win
XXXX Coins entry fee will give you 50% of whatever amount you win
0 Coins (Free) will give you 15% of whatever amount you win
NOTE No matter which option you choose, the full amount will be added to the leader-board and leader-board prizes (coming soon).

Pay 3% of the INITIAL prize pool (3% of 300,000 coins is 9000 coins) and you would win 100% of any prize you win. So if you won 85,000 coins you actually get all 85,000 coins

Pay 1.5% of the INITIAL prize pool (1.5% of 300,000 coins is 4500 coins) and you would get 50% of any prize you win. So if you won 85,000 coins you actually get 50% or 42,500 coins

Pay 0% of the INITIAL prize pool, you would get 15% of any prize you win. So if you won 85,000 coins you actually get 15% or 12,750 coins

The prize pool would increase by whatever the person chooses, (So if someone puts in 2000 Points, the prize pool increases by 2000 Points).

People would get FULL credit on the leader-board points no matter what they picked.

When we show what the users won, in parentheses show the amount they really won if it was less than 100% http://prntscr.com/omq5wq

The Tournament Buy-in amount name here: http://prntscr.com/onltw2 Would be "Optional"
