"A professional doesn't play games and neither does this upgrader. Upgrade ores by 30% up to 4 times."


The Professional Upgrader is a Premium-tier upgrader that increases ore value by 30% (1.3x multiplier) up to 4 times (a total multiplier of 2.85x). The Professional Upgrader was released during the 2015 Halloween Event starting 10/10/15. With a Tesla Resetter, the Professional Upgrader can be used 8 times on a single ore, bring the total multiplier up to 5.7x. However, this uses up more space. This item received a lot of negative attention until berezaa buffed it in the Layout Update.


  • The Professional Upgrader bares the appearance of 2 Doritos™ Bags, 5 Mountain Dew™ cans, a pair of 'Deal With It' glasses, an Illuminati symbol, and an Intervention Sniper; an obvious reference to the 'MLG' memes.
  • The Intervention Sniper can be used to direct ores in the centre of the conveyor for upgraders such as Freon-Blast Upgrader or Clockwork.
  • This item was buffed during the Layout Update patches on 3/4/2018 from a 10% upgrade to a 30% upgrade.
  • This item can be placed down unlimited times to power the Book of Knowledge for a x100 multiplier boost.
