The PBL Fallacy: Why Points, Badges, and Leaderboards Fail
The three elements most apps add first, points, badges, and leaderboards (PBL), are also the most documented failures in product history. In 2024, LinkedIn retired its "Community Top Voice" badges after internal data showed badge-motivated users prioritized quantity over quality. Foursquare scrapped mayorships in 2014 for the same reason: check-ins increased, but not the discovery behavior the business needed. Google News killed its badge system similarly. As gamification pioneer Yu-kai Chou puts it, "PBL is the scoreboard of a game, not the game itself." This often happens when designers mistake external rewards for internal motivation, a topic explored in Stop Chasing Success: Become Your Future Self Now with Dr. Benjamin Hardy.
Strava: Hyper-Local Micro-Competitions That Work
Strava built 180 million users without traditional badges, using segments, user-defined stretches of road or trail. Instead of one global leaderboard, they created thousands of winnable micro-competitions (the hill on your morning route). A 2022 Science Direct study confirmed that "Kudos" (social acknowledgement) increase future run frequency. Clubs grew 59% in 2024, with 14 billion Kudos handed out in 2025.
Key Lesson: Enable users to compete locally. Engineer competition size, not empty metrics.
The S-Curve Problem: When More Features Backfire
A 2025 peer-reviewed study in Frontiers in Psychology found gamification feature richness follows an S-shaped curve: adding features helps engagement up to a point, then reverses it. Example: Habitica (the most aggressively gamified productivity app) saw 100% of participants experience counterproductive effects, users got absorbed in managing the game layer, burying actual productivity. This pattern mirrors Cultural Transformations: Avoiding Common Mistakes for Successful Adoption, where adding more rules often undermines the core goal.
Key Lesson: If you're stacking streaks + points + badges + challenges + leaderboards, you're past the peak, not climbing it.
The Streak Trap: From Motivation to Obligation
Research from The Decision Lab shows streaks shift from motivational to obligational over time, from "I want to" to "I can't miss today." A 2023 Belgium study of ~2,500 adolescents found streak frequency correlates with FOMO and problematic smartphone use. The EU Digital Fairness Act (2026) targets addictive streak mechanics specifically. To understand how to build habits that feel like choice rather than compulsion, review 9 Micro Habits to Fix Your Attention, Energy, and Happiness.
Exception: Duolingo wraps streaks in agency, users choose their goal level and buy streak freezes. A streak you can't pause or influence is the design researchers flag.
Variable Reward Magnitude: Anticipation Over Loss Aversion
The gap between knowing a reward is coming and not knowing its size is one of the strongest engagement signals. Gameblazers (a fantasy card game) demonstrates three stages:
- Anticipation, Tap a pack; could be junk or the rare you've been chasing
- Reveal, Cards flip one at a time, resetting anticipation each time
- Celebration, Rare card triggers screen reactions, glows, haptics
Streaks run on fear of loss; variable rewards run on pull toward what's next. Opposite emotional engines, different sustainability.
Apple Watch: Completion Drive and the Gestalt Principle
Apple achieved 49.5% behavior change in 160,000 people using three activity rings (move, exercise, stand). The system relies on the Gestalt principle of closure: the brain is hardwired to perceive incomplete patterns as demanding completion. A 90% filled circle creates an open loop the brain wants to close. Users who regularly close rings are 48% less likely to experience poor sleep quality. For more on building physical routines that stick, see Fall Fitness Reset: 5 Habits to Get Back on Track & Feel Confident Again.
Key Lesson: Completion drive produces real-world positive outcomes, not engagement theater.
Competence vs. Badge Theater: Mastery Over Recognition
The 2024 Springer Nature meta-analysis found gamification reliably improves autonomy and relatedness but has minimal impact on competence, the need most tied to long-term intrinsic motivation.
What works:
- Peloton, Output measured in real time, Personal Records auto-flagged. The 100-ride badge means 100 actual rides.
- Chess.com, ELO ratings signal skill development
- Garmin, Training readiness and body battery scores
Build mechanics that signal you got better at the actual thing, not that you opened the app a lot. These principles align with John Maxwell's 5 Daily Habits: The Secret to Success | Personal Growth Plan, focusing on real growth rather than shallow metrics.
I studied hundreds of gamification implementations for mobile apps, and here's the thing. The three elements
every app adds first, like points, badges, and leaderboards, are also the three most documented failures in
product history. Meanwhile, Strava built 180 million users without a traditional badge in sight. An Apple Watch drove a
49.5% behavior change in 160,000 people purely through completion drive.
The Apple one is kind of wild, and we'll come back to it because how they did it is probably the most important point out
of all of the seven research-backed patterns I'm going to cover in this video. You're going to see what kind of
gamification actually works, what's theater, and the specific mechanics the best retaining apps in the world are
actually using. By the way, I'm Tim. I've spent over a decade designing software for companies like Spotify, and
I've helped clients reach the top of the US App Store working on exactly these kinds of problems. Now, pattern one is
what I call the PBL fallacy. PBL stands for points, badges, and leaderboards, the three mechanics every app reaches
for first. And the reason this leads the video is because of what happened in 2024. LinkedIn quietly retired its
community top voice gold badges. Their internal read was that badge-motivated users had been producing quantity over
quality, chasing the badge instead of sharing expertise. And this isn't new. It's actually history repeating.
Foursquare scrapped mayorships and badges in 2014 after their data showed gamification
drove check-ins but not the discovery behavior that business actually needed. Google News killed its badge system for
the same exact reason. The gamification OG, Yu-kai Chou, put it best. PBL is the scoreboard of a game, not the game
itself. You wouldn't walk into a baseball stadium, look at the scoreboard, and feel motivated to play
baseball, right? Most apps though build the scoreboard and forget to build the game. So, let's look at the counter
example, Strava. 180 million registered users and the engagement number that genuinely shocked me. Strava users
average 1 hour of real-world activity for every 2 minutes spent in the app. That's not a retention metric, that's
more like an influence metric. The mechanism doing most of the work is segments. A segment is any user-defined
stretch of road or trail. Run it and your time gets logged on a leaderboard sorted by age and gender cohort. Now,
that sounds like a leaderboard, which I just told you is kind of broken. But, here's the difference. Strava didn't
build one global leaderboard, they built thousands of hyper-local micro-competitions.
The hill on your morning route, the segment outside your office. These competitions are winnable and
winnability is the strongest predictor of competitive motivation. A 2022 Science Direct study confirmed this.
Kudos on Strava, the small social acknowledgement when someone completes a run, increase future run frequency. And
the social side has compounded fast. Strava's clubs grew 59% in 2024 alone, and the platform handed out 14 billion
kudos in 2025. Strava's lesson for founders is direct. Enable users to compete more locally. Engineer the size
of the competition rather than inflating empty metrics. And before we keep going here, if you want to chat about how any
of these patterns would apply to your app, we open up a few free design strategy calls monthly at Zipsnap. You
can grab your spot in the link below. Now, so far this might suggest the answer is just to add the right kinds of
mechanics. More features, but smarter ones. That's where pattern three comes in, and it's the most counterintuitive
of the seven, the S-curve problem. A 2025 peer-reviewed study in Frontiers in Psychology found that gamification
feature richness follows an S-shaped curve. Adding features helps engagement up to a point. After that point, more
features actually reverse engagement. The empirical proof here is Habitica, probably the most aggressively gamified
productivity app ever built. Daily tasks become quests. Habits become character stats. Missing a task damages your HP.
The peer-reviewed study on Habitica found that 100% of participants experienced counterproductive effects.
Users got so absorbed in managing the game layer that actual productivity behavior got buried. This is cognitive
overload disguised as engagement. If you're stacking streaks plus points plus badges plus challenges plus
leaderboards, the data says you're past the peak of the curve, not climbing it. Which brings us to the most dangerous
mechanic in the founder toolkit. Streaks. Pattern four is the streak trap. Research from the Decision Lab
found that streaks gradually shift from motivational to obligational the longer they run. Users move from I want to do
this to I can't miss today. The canonical case here is Snapchat. A 2023 Belgium study of almost 2,500
adolescents found that streak frequency correlates with FOMO, problematic smartphone use, and reduced social media
self-control. In 2024, the Nevada Attorney General filed litigation against Snapchat. And the EU Digital
Fairness Act heading toward a legislative proposal in late 2026 is specifically
aiming at addictive streak mechanics. So, if you're shipping a streak in 2026, know this. The longer it runs, the more
it shifts toward obligation. And you're shipping into space that's now being monitored by regulators. That doesn't
mean streaks are universally bad, of course. Duolingo has run hundreds and hundreds of experiments on theirs, and
the version they ship today obviously retains users. But notice how they ship it. Users choose their goal level. They
can buy a streak freeze. The mechanic is wrapped in agency. A streak you can't pause, can't influence, and can't escape
is the design researchers are currently flagging. Okay, so if streaks burn out at day 31, what works instead? Pattern
five is variable reward magnitude, anticipation not loss aversion. The gap between knowing a reward is coming and
not knowing how big it is. That's one of the strongest engagement signals in all of product design. Take the example of
Gameblazers, a fantasy card game where the pack opening flow is the heart of the product. The product has three
stages. Anticipation, you tap a pack, no idea what's inside, could be junk, could be the rare you've been chasing for
weeks. Reveal, cards flip one at a time. Each card resets the anticipation cycle. Same data, but one dopamine event
becomes five. And celebration, rare card hits, screen reacts, glows, haptics. That's why you tap the next pack. Now,
compare that to a streak. Streaks run on fear of losing what you built. Variable rewards run on the pull towards what's
next. Same surface behavior, opposite emotional engine. One burns out while the other keeps recharging itself. By
the way, we designed the entire Gameblazers app at Sipsap. And we do this for a lot of clients, including
Freecash, who's paid out over 300 million euros and are absolutely killing it on the gamification side. So again,
if you need help with this kind of stuff for your own product, we run a few free design strategy calls each month. Links
down below. Now, the Apple Watch thing I told you was possibly the most important part of this entire video. Here's what
they actually did. They built the entire system around one principle, completion drive. And that's how they got 49.5%
behavior change in 160,000 people. The activity ring system is possibly the most underrated
gamification design pattern in consumer tech. They've got three rings: move, exercise, stand. Close all three to
complete your day. The system runs on one principle from cognitive psychology, the Gestalt principle of closure. The
brain is hardwired to perceive incomplete patterns as demanding completion. A 90% filled circle creates
an open loop, and the brain wants to close it. Users who regularly close rings are 48% less likely to experience
poor sleep quality. This is exactly what great gamification design is all about. The mechanic produces a real-world
positive outcomes, not engagement theater. And here's the part most founders miss. Apple's rings work
because they make you want to finish what you started. Anticipation toward closure. That's the engine. If you can
choose which lever your app runs on, completion drive is a strong alternative. Pattern seven builds
directly on this. I call it competence versus badge theater. The 2024 Springer Nature meta-analysis on gamification
found something brutal. Gamification reliably improves a user's perception of autonomy and relatedness, but has
minimal impact on competence, the one psychological need most tied to long-term intrinsic motivation. Most
apps engineer recognition and forget to engineer mastery. Peloton is the cleanest counterexample of this. Members
who use the social and output features work out 15% more frequently, but the mechanism isn't competition, it's
competence feedback. Output is measured in real time. Personal records gets auto-flagged. The 100 ride badge means
something because it represents 100 actual rides. That's not theater, that's evidence of skill development. Chess.com
runs the same play with ELO ratings. Garmin's training readiness and body battery scores do it in fitness
wearables. Build mechanics that signal you got better at the actual thing, not mechanics that signal you opened the app
a lot. Now, if you found this breakdown helpful at all and you're wondering how this might apply to your own product,
for the last time, we open up a few free design strategy calls each month at Sipsup. The link's down below, as
always. Also, if you like this video, you'll probably also like this one, somewhere around here, where I break
down how Spotify, Tinder, and Netflix use psychology to dominate their categories. Now, until the next one,
have a great life.
The Apple Watch uses the Gestalt principle of closure, where the brain perceives an incomplete 90% filled circle as an 'open loop' demanding completion. This design led to a 49.5% behavior change in a study of 160,000 people, with users who regularly close rings being 48% less likely to experience poor sleep quality. The system produces real-world health outcomes, not just engagement metrics.
A 2024 meta-analysis found that while gamification improves autonomy and relatedness, it minimally impacts competence—the need most tied to long-term motivation. Effective systems like Peloton measure real-time output and auto-flag personal records, Chess.com uses ELO ratings to signal skill growth, and Garmin provides training readiness scores. These mechanics reward actual skill improvement, not just app usage frequency.
PBL elements are frequently added first but also most documented failures because they act as a scoreboard without creating meaningful game mechanics. Companies like LinkedIn, Foursquare, and Google News abandoned such systems after finding they encouraged quantity over quality, like posting low-value comments or checking in without genuine discovery behavior. Gamification pioneer Yu-kai Chou explains PBL is merely 'the scoreboard of a game, not the game itself.'
Strava avoids traditional badges by using user-defined 'segments' to create hyper-local micro-competitions, such as racing on a specific hill in your neighborhood. Instead of one global leaderboard, this generates thousands of winnable challenges tailored to individuals' daily routes. A 2022 study found that social recognition ('Kudos') boosts future activity, and clubs grew 59% in 2024, demonstrating that engineered competition size drives more authentic user engagement.
According to a 2025 peer-reviewed study, the relationship between gamification features and engagement follows an S-shaped curve: adding features like streaks, points, and leaderboards initially increases engagement, but beyond a peak, more features cause a reversal. For example, Habitica, a heavily gamified productivity app, saw 100% of participants experience counterproductive effects, becoming so absorbed in managing the game layer that it undermined actual productivity.
Research shows streaks shift from motivational to obligational over time, fueling FOMO and problematic usage, especially in adolescents. A 2023 study linked streak frequency to addictive smartphone behaviors, and the upcoming EU Digital Fairness Act targets such mechanics. Duolingo avoids this trap by wrapping streaks in user agency: learners choose their goal level and can buy streak freezes, making the streak something they can influence rather than a coercive obligation.
Variable reward magnitude, as seen in Gameblazers, generates engagement through anticipation of an unknown outcome (e.g., opening a pack to potentially get a rare card), followed by a reveal celebration with glows and haptics. This creates a ‘pull toward what’s next,’ whereas streaks rely on fear of loss. These opposite emotional engines lead to different sustainability levels, with variable rewards fostering longer-term motivation.
