Real-money infrastructure, two script tags deep.
Two script tags. One init call. A new revenue stream for your game — with no accounts, payments, or player screens to build.

Challenge.init({ program: '<<YOUR_PROGRAM_ID>>' });
</script>Any game can pay its players.
Puzzles, speedruns, arcade classics — Bounties and tournaments drop straight in, and Challenge funds the prizes.
Every game qualifies
A revenue stream for games that never had one — solo runs, puzzles, speedruns.
Zero prize risk
Challenge funds every prize and carries the exposure. You never hold player money.
Monetize from launch day
House-funded tournaments run with no calibration wait — a purse and a live leaderboard on day one.
Engineering you don't have to build.
The hard parts of real-money play — priced, monitored, and guaranteed by Challenge.
Fair bars keep players paying
Every bar is priced from your players' real scores — beatable enough to keep them trying, never a number you have to tune.
Zero cost to your load time
A 2KB stub paints the pill before your page finishes loading — your performance budget doesn't notice we're there.
Mispricing can't hurt you
Every live Bounty's pass rate is monitored around the clock — a bar gone soft takes itself off sale before it costs anyone trust.
Disputes designed out
The player always got exactly the deal they saw — terms freeze at payment, and an unfinished round refunds itself. Nothing to arbitrate, ever.
Safe for you. Fair for them.
You never touch player money — and money never moves on anything a player can fake.
Nothing to leak
Only a public program ID lives in your client. Secrets stay on your server — a compromised browser can't spend a cent.
Cheaters can't cash out
Scores enter only from your authenticated server, after the fee is already charged. There is no client path to money.
Compliance handled
KYC, age checks, state gating, responsible gaming — carried by Challenge, so you ship a game, not a gambling desk.
An afternoon, not a sprint.
- The whole build is on the right: a snippet, one record call, one server POST.
- Prove the entire flow on sandbox keys before a real dollar moves.
- Flip to your live key and earn a monthly revenue share on every Bounty — we only make money when you do.
