Overlay tools have been quietly changing the way League of Legends is played—and Riot just dropped the hammer on one of the most controversial features yet. What started years ago as simple jungle timers has turned into a full ecosystem of apps that track stats, automate builds, and now even predict your win rate before the game starts.

While Riot has mostly looked the other way for years, a recent ban on ultimate tracking overlays and the rise of AI draft predictors has reignited the debate. Should overlays be allowed? Should Riot just build these tools into the game? And where do we draw the line between smart tools and cheating?

Let’s break it all down.


🧩 What Even Is an Overlay?

Overlays are third-party apps that provide in-game information through external interfaces, usually through Riot’s public API. Popular overlays offer features like:

  • Jungle respawn timers
  • Summoner spell cooldown tracking
  • Enemy ultimate tracking (now banned)
  • Player ranks and win rates
  • Optimal build paths
  • Damage tracking and teamfight stats
  • And yes, some even offer ads or premium subscriptions

For many players, they’re now a default part of the League experience, especially in ranked.


🔒 Riot’s Official Stance: Ult Tracker Banned, Others Still Allowed

About three weeks ago, Riot banned overlays that track enemy ultimates—even if they’re tracked manually.

This move surprised many, considering summoner spell timers, jungle timers, and other combat tools are still allowed. Why ultimates crossed the line but Flash and Ignite didn’t? Riot hasn’t clarified.

But the fact they stepped in at all shows they’re finally drawing a line somewhere.


🧠 AI Win Rate Prediction Tools Now Exist

Just when you thought the overlay wars were cooling down, someone built an app that uses over 10 million matches of Riot API data to predict your win rate during champion select with 62% accuracy.

How it works:

  • You input champion picks as they happen
  • Set your rank (Gold, Plat, etc.)
  • The app calculates win chances based on team comp synergy, counters, and past results
  • If the win rate is low, you dodge
  • Over time, you climb

This isn’t just counter-picking. It’s based on nuanced stats like:

  • How Darius performs into Sion
  • But also, how Darius performs if the enemy team can kite him
  • The system goes beyond lane to analyze team-based win conditions

This isn’t even an overlay—it’s external, uses Riot’s legal API, and yet… it arguably gives players a huge edge in ranked.


🎯 So What’s the Problem?

It’s not just about fairness—it’s about accessibility, monetization, and competitive integrity.

  • Jungle timers are widely used. So why not build them into the game?
  • Summoner spell tracking gives huge value but isn’t banned.
  • Ult tracking? Banned.
  • Paid overlays? Allowed.
  • AI draft tools? Legal, but arguably game-altering.

And here’s the kicker: in China and Korea, jungle timers are built directly into the client. Tencent just… added them. Riot knows players use this info, so in those regions, it’s standard. In the West, you’re either using third-party tools—or getting outplayed by someone who does.


🧠 Why Riot Hasn’t Banned Everything

Technically, Riot could shut it all down. Every overlay pulls data from Riot’s API, and all Riot has to do is limit access to live game data.

But if they did that:

  • Fan tournaments and esports overlays would break
  • Stream tools and community content would suffer
  • Riot would have to take on the burden of building better tools themselves

Instead, they seem to be picking off features one at a time. First ult timers. Maybe more to come.


🎮 The MMO Comparison: Addons, But Worse

The debate feels eerily similar to MMO addon culture, where third-party tools range from helpful to game-breaking.

Games like World of Warcraft have dealt with this forever:

  • Some addons track bosses
  • Some automate rotations
  • Some make you an actual robot

League, however, is a competitive esport, and the stakes are higher. Overlay tools change how people climb, how they lane, and how they win—and most players have no idea how many tools are being used against them.


💸 Some of These Tools Are Monetized

Yes, some overlays now have:

  • Ads
  • Premium versions
  • Locked features behind paywalls

Is it really okay that your opponent might have better tools just because they paid for an overlay subscription?

Even worse—new players might assume this is normal.


💥 Riot’s Overlay Dilemma: Ban It or Build It?

If Riot wants to maintain competitive integrity, they’ve got a few options:

✅ Build It In

Add jungle timers, summoner spell tracking, and more directly into the client. It already exists in other regions.

❌ Ban It All

Kill the API access for live data, block overlays entirely, and go full anti-addon like some MMOs.

🤷 Let It Spiral

Hope people stop complaining and do nothing until someone builds an AI that plays the game for you.

So far, they’re doing a little of each. But with AI draft prediction, stat automation, and now banned features, the situation is boiling again.


Final Thoughts – Overlays Are Changing the Game

What started as a helpful tool has become a mini arms race. Players are using overlays for everything from build guides to enemy summoner timers, and now even win prediction tools based on 10 million matches.

Riot has banned ultimate tracking, but summoner timers and jungle tools remain legal, despite being arguably more impactful. AI-driven tools are already here, and Riot can’t stop them without gutting the API—which would hurt streamers, tournaments, and community projects.

So what happens next?

If Riot wants to protect competitive integrity, they’ll need to either:

  • Build the tools into the game
  • Or take a hard stance and shut overlays down

Until then, the advantage lies with whoever has the best app running in the background.
