first step is go to file explorer and then open "windows c:" then choose "program files 86">"steam">"steamapps">"common">"hernewmemory">"games">"scripts">"mechanics" after that search a file named "lottery.rpy" and open it as a txt file and edits the "ticket" code like this
r = renpy.random.randint(1,100)
if r <= 45: #60%
ticket = 100
but you just have change the "ticket = 100" with this number (300,500,and 1000) then you just "ctrl + s" and create a new game so the codes work
