   See attempts needed for desired certainty

• 1

  Low drop rates require many more attempts than expected

• 2

  A 1% drop rate doesn't guarantee success in 100 tries

• 3

  Bad luck protection exists in some games

• 4

  Track your actual attempts vs expected

• Thinking 1% means guaranteed in 100 tries

• Not understanding independent probability

• Rage quitting due to bad RNG streaks

• Not factoring in attempt time
