Cloning is the industry's open secret
Every successful indie game attracts copycats. Some clones are shameless asset rips. Others sit in a gray zone — similar mechanics, different art, plausible deniability.
These five cases show how cloning plays out in practice, what the original developers did, and what every indie dev can learn from their experience.
1. Threes vs. 2048
What happened
Threes was a puzzle game developed over 14 months by Asher Vollmer and Greg Wohlwend. It launched on iOS in February 2014 at $1.99. Within two weeks, a free clone called 1024 appeared. Days later, 2048 — a clone of the clone — went viral.
The outcome
2048 became more famous than Threes. It was free, open-source, and spread across every platform. The Threes developers published their entire email chain documenting 14 months of design iteration, showing how much thought went into every mechanic that 2048 copied in a weekend.
It didn't matter. 2048 had already won the attention war.
The lesson
Speed matters. By the time the Threes team responded publicly, 2048 was already a household name. If they had detected the first clone (1024) within days and acted immediately, the cascade might have been stopped before 2048 ever existed.
2. Flappy Bird and the clone flood
What happened
Flappy Bird, by Dong Nguyen, became the most downloaded app in the world in January 2014. When Nguyen pulled it from stores in February, cloners filled the vacuum. Within 24 hours of removal, over 200 Flappy Bird clones appeared on the App Store.
The outcome
Some clones were exact copies with different bird sprites. Others were "tributes" that rode the same keywords. Apple and Google eventually cracked down, but it took weeks. Several clones racked up millions of downloads before they were removed.
The lesson
A hit game with no clone monitoring is a sitting target. The Flappy Bird case is extreme, but it demonstrates how fast the cloning machine moves — and how slow store enforcement can be without developer-initiated reports.
3. Among Us and the mobile copycats
What happened
Among Us launched in 2018 but exploded in popularity in mid-2020. By late 2020, dozens of mobile clones appeared with near-identical gameplay: "Impostor," "Betrayal.io," "Spy Game," and others. Some copied the visual style wholesale — colored astronauts with no legs doing tasks on a spaceship.
The outcome
InnerSloth, the three-person studio behind Among Us, was overwhelmed. They had planned a sequel but scrapped it to focus on updating the original. They filed takedowns against the most egregious clones, but the volume was staggering.
Several clones on the Play Store exceeded 10 million downloads before removal. Some are still live under slightly altered names.
The lesson
Small teams can't manually monitor every store when their game goes viral. By the time InnerSloth caught up, clones had already captured a significant portion of the mobile market that Among Us itself hadn't reached yet.
4. Wordle and the gold rush
What happened
Wordle, created by Josh Wardle as a free web game, became a global phenomenon in late 2021. Within weeks, multiple paid apps called "Wordle" appeared on the App Store — some charging up to $29.99. Others like "Wordus" and "Word Guess" copied the exact gameplay with minor visual tweaks.
The outcome
Apple manually removed several of the most blatant rip-offs after media coverage. The New York Times acquired Wordle in January 2022, and their legal team pursued remaining clones more aggressively.
But the damage was already done. Players who searched "Wordle" on the App Store during those early weeks often downloaded a paid clone instead of finding the free original.
| Clone | Price | Downloads before removal |
|---|---|---|
| "Wordle!" (iOS) | $3.99 | ~200,000 |
| "Wordle - Word Game" | $2.99 | ~150,000 |
| "Wordus" | Free (ads) | ~500,000 |
The lesson
Name cloning is the fastest attack vector. If you don't monitor for your game's title appearing on stores you haven't launched on, someone else will claim it. Trademark monitoring should start before your game goes viral, not after.
5. Vampire Survivors and the survivors-like wave
What happened
Vampire Survivors by Luca Galante launched in early access on Steam in December 2021. By mid-2022, the "survivors-like" genre existed as a category on Steam, and mobile stores were flooded with games borrowing its core loop: auto-attacking, wave survival, roguelike upgrades.
The outcome
This case is more nuanced. Many "survivors-likes" are genuine genre entries — games that take the core concept and build something new. But others are direct clones with copied asset styles, identical upgrade systems, and confusingly similar names.
Our own scan of Vampire Survivors found 6 matches across app stores, with similarity scores ranging from 73% to 91%. The top match scored 85% on name similarity alone.
The lesson
When your game defines a genre, the line between "clone" and "genre entry" gets blurry. Automated monitoring with similarity scoring helps you focus on genuine threats — the 90%+ matches — instead of wasting time on games that just happen to share your genre.
The common thread
In every case above, the developers found out about clones too late. By the time they responded — through public statements, DMCA takedowns, or legal action — the clones had already captured downloads, revenue, and mindshare.
The pattern is consistent:
- Indie game gains traction
- Clones appear within days to weeks
- Developer doesn't notice for weeks to months
- By the time they act, the damage is done
What you can do differently
The developers behind these games were talented, successful, and blindsided. The only thing they lacked was early visibility into what was being published on stores they weren't watching.
Daily automated monitoring closes that gap. You get an alert the day a suspicious listing appears — not the day a frustrated player tweets about it.
