Notes

  • Generators produce rewards periodically for a few days
  • Rewards depend on the upgrade level
  • No need to collect your rewards on time: they will stack and can be retrieved anytime
  • Uncollected rewards are sent by mail once the generators disappear
  • No need to rush the first minutes: you receive full rewards for the ongoing period you invest in
  • But if you miss the first period completely, your rewards will be reduced
