There was once me and my gf go arcade, then see got 1 that is
past the lvl A, so we try our luck, change $20. Who know we put in
the 1st $5, the catcher jam, lppl, ask the person come reset the
level bar. No choice, play and see if have the luck to hit
jackpot.
Play till last $1 liao, bar just past the level A, and people
watching how come got people play when the bar level so low. And
with the last $1, we kanna the jackpot. Damn lucky man.
