Robinhood: confetti on trades
Robinhood celebrated trades with confetti and offered free-stock “scratch card” rewards. It removed the confetti in 2021 amid scrutiny. In Jan 2024 it paid $7.5M to settle Massachusetts gamification charges, which barred celebratory imagery tied to trading for Massachusetts accounts. It neither admitted nor denied those allegations.

What they did. Confetti animations after first trades and deposits, free-stock "scratch card" rewards for referrals, push notifications and "most popular" lists.
The mechanism. [Analyst inference] Sudden celebratory rewards GT#30 (Actionable Gamification Ch.11, p.297) and mystery rewards GT#72 (Actionable Gamification Ch.11, p.295) attach Unpredictability & Curiosity to the trade itself; a random payout tied to money is Hooked's cautionary extreme HK-RWD14 (Hooked Ch.4). Popularity lists add social proof that can herd new investors INF-T-SP-04 (Influence Ch.4, p.90).
The outcome. Confetti removed March 31, 2021 (2021). Massachusetts settlement $7.5M (2024) Case grade A. From a regulator, a public filing or a peer-reviewed study. covering confetti, scratch tickets, free stock, push notifications and popularity lists; celebratory imagery tied to trading is barred for Massachusetts accounts. Separately, FINRA's ~$70M action (June 2021) covered misleading information, outages and options approvals, not confetti.
What it means at your stage. In finance, health, gambling-adjacent products or anything used by minors, never put chance or celebration rewards on the risky action itself. Celebrate learning milestones instead: finishing a lesson, setting up diversification.
Caveats. A settlement in which Robinhood neither admitted nor denied the gamification allegations. Mechanism link Evidence grade D. Practitioner framework or anecdote: plausible, untested. [Analyst].

The techniques behind it
Each one is a starting point, not a recipe. Gamify It turns a technique into an experiment card for your product: the change, the metric, the guardrail and how long the test needs at your traffic.
- TechniqueEvidence grade C. Limited evidence: few or small studies.
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.
- TechniqueEvidence grade C. Limited evidence: few or small studies.
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.
- TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
Accurate popularity cues
true "most popular" labels and usage counts
Show popularity only as it really is: "Most popular" on the plan most chosen, a defined count of active teams, "copied 3,400 times" on a template. People treat what many others do as a sign of what is right, so a true count helps the uncertain; an inflated one invites distrust once noticed.
