Twitch Predictions Sniper: Auto-Bet on Predictions
Twitch Predictions are timed gambles - they open, run for a minute or two, and close. If you are not watching chat or are AFK, you miss them. The Predictions Sniper enters them for you automatically, using the strategy you pick. Set it once, watch streams normally, let the channel points handle themselves.
When you keep missing the predictions
Predictions on Twitch are short-window gambles. A streamer (or a mod, or an automated bot) opens one - "will they clear this raid first try?" - and you have a minute or two to weigh in with channel points before voting closes. If you are AFK, in another tab, watching with chat closed, or just not paying attention to that side of the screen, you miss the entry window entirely.
Predictions Sniper enters Twitch Predictions for you automatically, using a strategy you configure. The points get bet, won, or lost without you clicking anything in the moment.
How the Predictions Sniper works
Once Predictions Sniper is enabled, the extension watches every Twitch tab you have open for new predictions. When one starts, the Sniper waits until a configurable number of seconds before voting closes (minimum 2 seconds), looks at the current vote distribution, picks an option according to your selected strategy, and submits the bet.
You do not need to keep chat open or be on the tab - the Sniper runs in the background of any open Twitch tab. If you have chat open, you will see the prediction menu flicker for a split second when the Sniper enters. Otherwise it is invisible.
Four ways to pick a winner: the strategy modes
The Sniper has four selectable vote-selection modes. Pick the one that matches how you want to play.
- Most Votes (default) - bet on the option leading at the time of entry. The "go with the crowd" play. Lower payouts when you win, but a higher win rate over time.
- Least Votes - bet on the underdog at the time of entry. Higher payouts when you win, lower win rate. Good for high-variance fun runs.
- Highest Return Ratio - bet on whichever option has the best per-point payout at the moment. The math-driven "chase the value" mode.
- Lowest Return Ratio - bet on whichever option has the safest per-point payout. Closest to a guaranteed win, with smaller multipliers.
The strategy applies to every prediction the Sniper enters. If you want different behavior on different streamers (more aggressive on one streamer's predictions, conservative on another's), use the per-stream overrides covered in the next section.
Tuning bet size, margin, and timing
Beyond the strategy mode, four global settings control how the Sniper behaves on every prediction:
- Bet % - what percentage of your channel points to wager on each prediction. Set this to a small number (1-5%) for slow long-term play, or larger for high-variance runs.
- Max num of points - a hard cap on how many points the Sniper can bet at once. Useful as a safety net when your point balance is high - keeps you from accidentally yoloing the whole stack.
- Min vote margin % - only enter a prediction if the gap between the two options exceeds this percentage. Use this to skip the close coinflips and only bet when the crowd has a clear lean. (Not applied when using the Return Ratio strategy modes.)
- Seconds before close - how many seconds before voting closes the Sniper enters its bet. Minimum 2 seconds. Later entry means more accurate vote distribution data, but cuts it closer to the wire.
These are the global defaults. To override for a specific streamer, click the Sniper settings button under the chat on that stream - per-stream settings stick to that channel only. The whole settings set is exportable and importable, so your tuning survives reinstalls.
Pair it with Predictions Notifications
If you want to know what the Sniper is doing in real time (or if you like manual control on some predictions and auto-snipe on others), turn on Predictions Notifications in the same settings section. Browser notifications fire when a prediction starts on any Twitch tab you have open and when it resolves with a result. Useful when you have chat closed, are in another tab, or have the browser minimized.
A sub-toggle adds an audio ping along with each notification (off by default). First-time enable prompts your browser for Twitch.tv notification permission - allow it and you are done.
How to enable it
- Install Previews from the Chrome Web Store, Firefox Add-ons, or Edge Add-ons.
- Click the Previews icon in your browser's toolbar.
- In the Twitch settings panel, find Predictions Sniper. Toggle it on.
- Set the global defaults: pick a strategy mode, set the bet percentage, max points, min vote margin, and seconds-before-close to your taste.
- Optional: also enable Predictions Notifications right below it for real-time browser pings on predictions start and end.
- Open any Twitch stream you watch regularly. The Sniper runs in the background from now on - no further action needed.
- Optional: click the Sniper settings button under the chat on a specific stream to set per-stream overrides for that channel.
What else Previews can do for you
Predictions Sniper pairs naturally with the rest of the Previews toolkit. If you spend enough time on Twitch that auto-betting is worth setting up, you will probably also want:
- Auto-Refresh on Twitch Errors - automatic recovery from #1000, #2000, #3000, #4000, and #5000 errors. Pairs especially well with the Sniper since the Sniper needs an open Twitch tab to do its work, and auto-refresh keeps that tab alive through interruptions.
- Clip Downloader - one-click MP4 downloads on every Twitch clip page.
- Multi-Stream & Multi-Chat - watch and chat across multiple Twitch streams at once. The Sniper enters predictions on every Twitch tab in your layout in parallel.
- Sidebar Favorites - pin the streamers you watch (and bet on) most to the top of the Twitch sidebar.
- Plus FlashBang Defender, picture-in-picture, fast-forward to live, voice typing, hover previews for clips and directories, and more.
Frequently asked questions
How do I auto-bet on Twitch Predictions?
Install Previews and enable Predictions Sniper in the Twitch settings panel. Pick one of the four strategy modes (Most Votes, Least Votes, Highest Return Ratio, Lowest Return Ratio), set your bet percentage, point cap, vote margin, and seconds-before-close, then close the settings. The Sniper enters every 2-option prediction on every open Twitch tab from then on.
Does this work on predictions with more than 2 options?
No - currently the Sniper only handles 2-option predictions. Three-way and four-way predictions get skipped automatically (nothing is bet). The strategy logic is built around head-to-head vote math, which does not generalize cleanly to multi-option predictions. Two-option predictions are by far the most common type, so the Sniper still catches the majority.
What is the best Predictions Sniper strategy mode?
There is no single best mode - they trade win rate against payout size. Most Votes wins more often but smaller. Least Votes wins less often but bigger. Highest Return Ratio chases value mathematically. Lowest Return Ratio plays it safer for steady-but-modest growth. Most users start on Most Votes with a small bet percentage and switch modes once they have a feel for which streamers' predictions resolve which way.
Can I have different Sniper settings per streamer?
Yes. The settings in the Previews popup are global defaults. To override for a specific stream, click the Sniper settings button under the chat on that stream - per-stream settings persist for that channel only. You can run aggressive bets on one streamer's predictions and conservative on another's. All settings (global + per-stream) are exportable and importable from the Previews settings panel.
Do I need to keep the Twitch tab open for the Sniper to work?
Yes - the Sniper runs in the background of any open Twitch tab in your browser. The tab does not need to be focused or visible, and chat does not need to be open, but the tab itself does need to exist. If you close all Twitch tabs, no predictions get sniped until you open one again.
Does this work on Kick or YouTube?
No - Predictions Sniper is Twitch-only. Twitch's Predictions feature is unique to Twitch, and Kick and YouTube do not have an equivalent channel-points betting system the same way. Most other Previews features (Multi-Stream, Sidebar Favorites, FlashBang Defender, picture-in-picture, fast-forward, and so on) do work cross-platform.
