  Rewards of the hunt with natural stopping points

  discovery that knows when to stop

  Let users search for useful or interesting things where the next item is uncertain, mixing what they asked for with occasional discoveries. Build in endings: a daily drop at a set time, 'you're all caught up' markers and session summaries.

• TechniqueBModerateEvidence grade B. Moderate evidence: solid studies with some limits.

  Rewards of the self: instant feedback and visible progression

  feel competent, see progress

  Break hard work into small steps that give immediate feedback about the task, show progress markers, and unlock more advanced tools as users show they are ready.

  Fit the reward to why people come

  reward that matches the motivation

  Before designing rewards, interview at least five customers about what they find enjoyable, encouraging or satisfying, and match the reward to the reason they came: social, material or mastery. Then check how often each reward lands and whether users notice it.

• TechniqueDPractitionerEvidence grade D. Practitioner framework or anecdote: plausible, untested.

  Stack social, material and mastery rewards in each loop

  three kinds of payoff

  Map each core loop on three reward types and fill the gaps: a social payoff (who responded), a material or informational payoff (what's new or useful), and a mastery payoff (progress or completion). Score the coverage before adding mechanics, and add small, harmless surprises.

  Easter Eggs / Sudden Rewards (GT#30)

  surprise reward

  A reward users did not know existed, set off by something they did not know about, such as a rare refund on a card purchase or a hidden badge for an unusual moment. It sparks delight, word of mouth and speculation about what caused it.

  Mystery Boxes / Random Rewards (GT#72)

  known trigger, surprise reward

  Completing a known action earns a reward whose content stays hidden until it is revealed, like a chest after a weekly goal. Show the box before the reveal, guarantee a worthwhile minimum and rotate the pool; never sell the boxes.
