If you open the file in Notepad or some other text editor, you’ll get the source code. Near the top, you’ll find

 // !-------------------------!\\
// start stuff you should edit \\

var minflezz = 10000;		// script will stop playing if flezz would drop below this level
var maxwins = 5;			// how many times you want to win. usually 20, if you're aiming for your daily antifreeze
var betamount = 1;			// how much to bet. usually 10000, again for antifreeze
var debug = false;			// set to true to see debug output in error log
var betmod = false			// you should just leave this false.. really.

 // !---------------------! \\
// end stuff you should edit \\

Just change betamount to 10000 and maxwins to 20.
