Three stages
Thirty seconds stand between you and your rivals. Here is the run of play.
Paste any task. The AI engine classifies it, titles it, sets difficulty, and structures test cases in seconds.
Invite your rivals. Once slots are filled, a 30-second ready check begins. Everyone enters simultaneously.
Solve it first. The deterministic judgment engine validates submissions server-side to the millisecond.
Four formats
Every format has its own win condition and scoring rules. Pick the arena that plays to your strengths.
Functions, algorithms, and data structures in a sandboxed editor. JavaScript and Python supported.
›fn reverse(s) -> s[::-1]
First to pass all 20 hidden tests
Scored by percentage of test cases passed
General knowledge, pop culture, and history. The correct answer is hashed and locked before anyone enters the room.
›In what year did...?
First correct submission wins
No partial credit — correct or incorrect
Puzzles, riddles, and lateral thinking. The answer is objective. The trap is always the obvious choice.
›If A < B and B < C...
First correct submission wins
Closest numeric or text match on timeout
Speed arithmetic, equations, and proofs. Pure calculation against opponents who are exactly as fast as you.
›the sum of x squared plus y
First correct submission wins
Closest numeric value on timeout
The engine
The AI engine is a creation assistant, not a referee. It reads raw task briefs, structures the details, and sets up test cases.
Before any lobby goes live, the room creator has full editing control over the title, difficulty, and test cases. The winner is always decided by a deterministic system.
Paste blocked
Clipboard paste is disabled for the full live arena — coding and trivia.
Tab monitoring
Leaving the arena tab disqualifies you instantly — no second chances.
Split view & side panels
Chrome split view, AI sidebars, and right-click assistant panels are detected — with a warning before removal.
Sandbox execution
Every submission runs in an isolated container. 5s timeout, 128MB RAM cap.

Coins, not cash
Hosting is free. You never pay to create an arena — only competitors pay the entry fee at start. Each competing player pays 100 coins when the arena goes live. That entry fee funds the bounty — the winner takes the full pool.
Coins are non-transferable values inside Bountixx. They drive progression and competitive stake, not cash transactions.
