Quoted from roger0043:Neo, you are so right on that one. Gauntlet sucked down countless numbers of my quarters when I was about to die.
I was lucky, the arcade that had a Gauntlet had a prototype one that didn't delete foods. Once you learned the levels and got your skill up a bit, you could play it as long as you wanted. The local record: 11M points, found out that after level 999 it wraps back to level 8, 37 hour game. The guy ran up enough health that he left it sitting overnight while the arcade was closed and 60,000 health later the game was still going. My personal best was a 10-hour game, 450 levels, 4.5M points which was good enough for #2 on the Elf high score board.
