i have got working keeps count of games won , lost, assigning score based on amount of attempts/lives saved haven't been able find way keep total score of games played. each game unfortunately has seperate score. if can advise me on way of doing this, appreciated.

create int totalscore variable wincounter, losecounter , score defined. increment after each call scoregame()

score = scoregame(attempts); totalscore += score; system.out.println("your score is: " + score); 

if want permanently save statistics between sessions it's whole nother story. need write scores file after each round , start program reading score file. it's hardly impossible, requires bit more code.
