How Predictions Work

Viewers predict your role in first blood of every match. Pick one of four outcomes before the window closes — you're either right or wrong, and it counts toward your record.

0:30Window Closes
4Outcomes
5:00Remake Cutoff
KILLStreamer scored the kill
ASSISTStreamer assisted the killer
VICTIMStreamer was killed
MIAFirst blood happened elsewhere
Match Timeline
00:00Game loads — predictions have been open since champ select (a dodge resets them and reopens next champ select). Last calls before the 0:30 lock.
00:30Window closes. No new predictions accepted. Calls are final; the system watches for first blood.
~03:00First blood typically lands. The round resolves: viewers who called the right outcome get +1 correct, everyone else gets +1 wrong.
5:00Remake cutoff. If the match ends before this point (DC remake), the round is voided — nothing counts toward anyone's record.
Stream Delay

Run a stream delay to stop snipers? Set it in Settings → Stream Delay (in minutes). GamerNODE holds the lock and the First Blood reveal that long, so your viewers' predictions and the result stay in sync with their delayed stream — the overlay also auto-buffers for normal Twitch latency.

Your Record

Every viewer keeps a record per channel — correct calls, wrong calls, and accuracy. Records are channel-specific; the one you build here exists only on this channel.

Correct vs wrong
Call the right first-blood outcome and you gain +1 correct; miss and you gain +1 wrong. Your record shows both, e.g. 47–18 · 72%. It's free — no points, no rewards, no cash value.
Accuracy
Accuracy is simply your correct calls divided by your total calls. The more rounds you play, the more it settles toward your true hit rate.
Leaderboard
The channel leaderboard ranks viewers by accuracy first; total games played breaks ties, so a sharp regular outranks a lucky newcomer. It's a purely cosmetic standing — bragging rights only.
Chat Messages

GamerNODE can post in your Twitch chat at key match moments. Each message type is opt-in and configured in Settings.

Predictions Open
Predict the streamer's role in first blood: KILL / ASSIST / VICTIM / MIA. Window closes at 0:30 game time.
Predictions Locked
Predictions closed. Watching for First Blood.
Result
First blood resolved — the streamer's role is announced, with how many viewers called it right vs wrong.
Troubleshooting
League client not detected
GamerNODE reads your local League Client API to detect game phases. If detection fails: confirm League is running, restart League, then restart GamerNODE. If your install is in a non-standard path, point it at your install in Settings.
Twitch chat messages not posting
Twitch chat-write requires the user:write:chat + user:bot scopes. If you signed in before granting these, sign out from Settings and sign back in to re-consent. If a type is enabled but still not posting, check your Twitch account isn't on chat cooldown.
Prediction window didn't open
The window only opens for ranked Solo/Duo games on Summoner's Rift. Every other mode — Flex, normals, ARAM, Arena, Swarm, TFT, customs, tutorial, and bot games — is excluded. If you're in a ranked Solo/Duo game and it still doesn't open, check the connection indicator in the header.
Server connection lost mid-game
If GamerNODE loses its connection during a match, predictions in flight are preserved server-side. The app reconnects with exponential backoff. If you're disconnected for more than 60 seconds, viewers see a "channel offline" message until you're back.
A game was voided unfairly
Voided games follow Riot's official remake rule — any match ending before 5:00 is treated as if it never happened. Predictions can't resolve fairly, so no win or loss is recorded. If you believe a game was incorrectly voided, contact support with the game ID from History.

The Call

Four ways it plays out

Every game has exactly one First Blood. Before it happens, viewers pick the streamer's role. One of these is the truth.

K
Killer

Your streamer lands the killing blow on the game's First Blood.

A
Assist

There for the play, tagged the target — but didn't get the kill.

First Blooded

First to die. Your streamer is the First Blood.

No participation

Farming, roaming, recalling — nowhere near the action.

The Loop

From your game to their guess

No Riot API keys, no scoreboard scraping. GamerNODE reads the live game off your own machine and runs the round on your overlay.

STEP 01
Run the companion app

A lightweight desktop app reads your live League game locally and pairs once to your Twitch channel. Launch it, go live, forget it's there.

STEP 02
Chat locks in

When a game starts, the prediction prompt opens on your stream. Viewers pick one of four outcomes — and watch the live tally shift in real time.

STEP 03
Overlay resolves & scores

The instant First Blood drops, GamerNODE classifies the streamer's role, scores every prediction, and builds the channel leaderboard.

What's next

First Blood is just the first first

One engine, many milestones. If chat loves calling First Blood, the same prediction loop rolls out across the map.
