there is no way to complete level 2084 without using 10 bars unless the “stars aligned “ and you happen to have a party favor plus spaceship plus timed boosters. Those 10 bars can be bought of course but if trying to progress without purchasing gold bars then the completion of chocolate boxes that end in 8 or 25 bars is the only way . See picture above as advancing a level is the only way to win the next chocolate box. Yuk!
