It's hard to understand what you are asking due the chopiiness of how you are asking it.
If I understand you right, you want to save a variable for everyone, so that if they won a previous game they get an extra HP (whatever that is). I'd use a hash table.
Create a small hash table. For each item (username) you can set data values (total won, total lost, high win, extra points, etc.) You'd read it back in at the start of the next game and adjust it accordingly.
Basic hash table commands are:
hmake game 100
hload game game.hsh
hadd game username data1 data2 data3
hdel game user
hsave game game.hsh
