01
Everyone starts equal
Every serpent enters with the same starting state. Position, timing, movement, and extraction decisions create the advantage.
Live extraction · W1 / W2
Steer. Survive. Extract.
Build your line, carry arena value, and choose when to bank it—W1 for safety or W2 for a higher-pressure finish.
Training and Ranked use no wallet funds. Cash Arena is optional, eligibility-gated, and can lose the full entry plus disclosed fee.

What makes COIL clear
02
Risk stays visible
The closing storm and two extraction windows are shown in the HUD, so you can decide when to secure your run.
03
The server decides results
Movement, collisions, value, placement, and match results come from the authoritative game server—not from a player's browser.
How one match works
Learn the core loop in under a minute.
Every match starts equal. Your route, boost use, extraction timing, and survival decide what you secure.
- 01
Steer and collect
Aim with your pointer, collect arena value to grow, and use boost only when the speed is worth the mass it spends.
- 02
Extract at W1 or W2
Hold the extract control inside the live rim sector to secure value early, or stay longer and accept more pressure.
- 03
Leave or chase the crown
Exit with secured match value, or remain in the collapsing arena and contest the final crown.
Game modes
Choose competition without hidden wallet risk.
The mode selector separates learning, rating, and any real-value contest before you enter a queue.
No wallet risk
Training
Learn movement, boost cost, storm pressure, and extraction timing without a buy-in or wallet balance requirement.
No wallet risk
Ranked
Compete for skill rating and leaderboard position. Ranked results affect SR, not your wallet balance.
Limited rollout · optional
Cash Arena
A real-value USDC contest mode now rolling out in stages. The rollout is expected to reach 100% of otherwise eligible accounts in supported locations by 1 September 2026. It is not yet available to every account; age, identity, security, risk, and live service checks apply, and the full buy-in plus disclosed fee can be lost.
Trust by design
Fair play is built into the match.
Betacoil combines server-authoritative gameplay, layered anti-cheat checks, replay-backed evidence, and clear conditions before money can be involved.
01
Server-authoritative anti-cheat
The server owns match state and results. Live request validation and deterministic replay checks prevent manipulated client state from becoming an accepted result.
02
Money is never the default
Training and Ranked do not put wallet funds at risk. Cash Arena is a separate optional mode with additional checks and disclosures.
03
Rules before the decision
Eligibility, total amount locked, fees, maximum possible loss, and settlement status must be shown before a Cash queue is confirmed.
Start with training
Understand every decision before you play.
