For the newest and most updated builds please check out Idleon Toolbox or Idleon Companion

Both Idleon Toolbox and Idleon Companion feature the same builds, as well as lots of other useful tools to help you keep track of your progress! Idleon Toolbox requires you to make a copy in Google Sheets to use the builds tab. If you're uncomfortable with spreadsheets or on mobile, use Idleon Companion.
