What it does
Everything runs in your own browser, on your own BC.Game tab.
Bets until your goal
Choose the base stake and how much to earn. The round ends on a win once you're up by that much.
Martingale built in
After a loss the next stake is multiplied; after a win it goes back to the base. Red, green or random.
Safety stops
Stops when the balance can't cover the next bet, recovers from dropped connections, and refuses to start when you're signed out or empty.
Loop PREMIUM
Play round after round with a 0.5–6 hour break, and finish once the whole run has earned your total goal.
Full control PREMIUM
Your own color order, multiplier and random range, a max lose streak, and higher stakes and goals.
Stop or pause after a win
End cleanly: stop or pause right now, or wait for the next winning bet. Change settings while paused.
The settings, explained
Two settings are all you need to start. The rest fine-tune how stakes grow and how long it runs.
Amount per bet
FREEFree: up to $1Your base stake in USD. Every round starts with it, and after a win the stake goes back to it.
Until earn $
FREEFree: up to $10The goal for one round. The round ends on a win once your balance is up by this much since the round started. Without Loop, that's the end of the run.
Multiplier
PREMIUMFree: 2After a loss the next stake is the last stake × this number. A win resets it to Amount per bet.
Range
PREMIUMFree: offAdds a little randomness: each loss multiplies by a random value from Multiplier to Multiplier + 0.2, so stakes aren't perfectly regular.
Order
PREMIUMFree: default patternThe color pattern for the bets: 0 = red, 1 = green, any other character = random. It's shuffled at the start of each run.
Max lose streak
PREMIUMFree: no limitAfter this many losses in a row, the stake goes back to Amount per bet and the round keeps its goal, so one long streak can't keep doubling the stake.
Loop
PREMIUMFree: one roundPlays round after round. After each round it waits the interval you set on the slider, plus up to 18 minutes at random, then starts the next one.
Until total earn $
PREMIUMThe goal for the whole Loop run. The run finishes once your balance has gained this much since Start (checked as each round ends). Blank = loop until you stop.
Close
PREMIUMCloses the BC.Game tab while waiting between Loop rounds; a new tab opens when the next round is due.
What happens on its own
Recovery instead of a crash
With no Max lose streak, when the balance can't cover the next multiplied stake, the stake drops to $0.1 and the rest of the round aims for +$5, so the run keeps going instead of stopping cold.
Never bets money you don't have
Before every bet the balance is checked. When even the base stake isn't covered, the run stops and tells you.
Survives hiccups
A dropped connection or a missed result is noticed and the bet is placed again only if it never went through. A page that loads slowly is retried.
Always in USDT
If another coin is selected in the wallet, bcauto switches back to USDT before a round starts.
Settings locked while betting
So nothing changes mid-bet by accident. Pause to edit; Resume carries on with the new settings.
A clear log
Every bet, win, loss, stake and balance is listed in the popup, with the time, so you can see exactly what happened.

The free version is the real thing with sensible limits. Premium unlocks every setting.

Installation guide
About 2 minutes. bcauto isn't in the Chrome Web Store, so it's added as an "unpacked" extension, which Chrome allows with Developer mode on. The pictures show where to click (highlighted in gold).
Download and unzip
Download the zip, then unzip it into a folder you'll keep, for example Documents\bcauto. Chrome runs the extension from this folder, so don't delete or move it later.
Windows: right-click the zip → Extract All…. Mac: double-click it.
Open the extensions page
Type the address into your browser's address bar and press Enter:
| Chrome | chrome://extensions |
| Edge | edge://extensions |
| Brave | brave://extensions |
Turn on Developer mode
Switch on Developer mode: top right in Chrome and Brave, in the left sidebar in Edge. New buttons appear, including Load unpacked.
Load the folder
Click Load unpacked and choose the folder with manifest.json directly inside it. The bcauto card appears.
Unzipping made a folder inside a folder (bcauto\bcauto)? Pick the inner one.
Pin it to the toolbar
Click the puzzle-piece icon next to the address bar, then the pin next to bcauto. Its icon now sits in the toolbar, one click away.
Sign in or sign up on BC.Game
bcauto bets from your own BC.Game account in this browser, so sign in first (or create an account with Sign up). Signed out, the popup says "🔑 Sign in or sign up on bc.game first" and Start won't run.
Deposit USDT
Bets are placed in USDT, so deposit USDT on BC.Game (bcauto switches the wallet to USDT by itself). Keep more than one stake: after losses the stake grows, and a run stops when the balance can't cover the next bet. With an empty wallet the popup says "💸 Deposit on bc.game first".
Open Trenball and press Start
Open Crash → Trenball and click the bcauto icon. Set Amount per bet and Until earn $, then press Start. Not on Trenball yet? Start opens it for you.
Turn on premium (optional)
Click ⭐ after "Advanced". Paste your key and press Save, or pick the days and press Pay. The badge turns green and shows the time left.
Updating to a new version
Download the new zip and unzip it into the same folder, replacing the old files. Then on the extensions page click the ↻ reload icon on the bcauto card. Your settings and key stay.
Chrome warns about Developer mode
Chrome may show "Disable developer mode extensions" when it starts. That's normal for unpacked extensions: close the message (don't click Disable) and bcauto keeps working.
Troubleshooting
"Manifest file is missing or unreadable"
You picked the wrong folder. Choose the one that has manifest.json directly inside it (often the inner folder after unzipping).
The popup says "Sign in or sign up on bc.game first"
Sign in to BC.Game in the same browser profile, then open the popup again.
The popup says "Deposit on bc.game first"
Your wallet is empty or can't cover the first bet. Deposit on BC.Game, or lower Amount per bet.
"bc.game isn't available in your region"
BC.Game doesn't accept players from your location, so bcauto won't run there.
"⚠️ page elements not found" or Start does nothing
Reload the BC.Game tab and wait until the game has fully loaded, then press Start again. Make sure you're on Crash → Trenball and the browser window isn't very narrow.
My key isn't accepted
Copy it exactly as shown after paying (BCA-XXXX-XXXX-XXXX-XXXX). "Already running on 2 profiles" means another profile is using it: stop the run there, or wait a few minutes.
The extension disappeared or shows an error after a while
The folder was moved or deleted. Put it back (or unzip again), then click Load unpacked once more.
FAQ
Will it make me money?
No one can promise that. bcauto automates a betting pattern; the outcome of every bet is still chance, and the house keeps its edge. Long losing streaks happen. Set amounts you're fine losing.
Does it need my BC.Game password?
No. It works in the BC.Game tab you're already signed in to and never asks for your login. The license server only sees your license key.
Why won't it start in my country?
BC.Game doesn't accept players from some regions. bcauto checks your location and won't run where BC.Game isn't allowed.
Can I use one key on several computers?
Yes, on up to 2 Chrome profiles running at the same time. A profile only holds a spot while a run is going; stop it to free the spot.
What happens when premium runs out?
The extension keeps working as the free version. Pay for more days on the same key whenever you like.
Is this made by BC.Game?
No. bcauto is an independent tool and isn't affiliated with or endorsed by BC.Game.
