Anyone playing right now is a Pioneer: an early tester whose feedback (via the Feedback page) directly shapes what we build, polish, and prioritize. The May 2026 monthly prize pool ($225) is guaranteed by HAG_Ai regardless of public sponsorship — so the competition is real, even on day one.

Two ways: (1) Hit 10/10 in any single round — you instantly get $1 USDT (up to 3 paid instant wins per player per month; beyond that, your 10/10 still counts on the leaderboard but doesn't pay out). (2) Finish in the top 3 of the monthly leaderboard for an additional $50 / $25 / $10 USDT at month end. Both stack.
Each player's best single run in the current month is what counts (highest score, fastest time). Only runs scoring 5/10 or higher qualify for the leaderboard. Top 3 at month end win $50 / $25 / $10 USDT respectively. Months reset on the 1st of every month at 00:00 UTC. Past winners are listed permanently on the Past Winners tab.
Ties are broken by total time (faster wins). If still tied, the earlier submission wins. Each name only counts once per month — keep playing, and only your best run is on the board.
Only filled positions are paid. If only 2 distinct players play, only 1st ($50) and 2nd ($25) are awarded. The unfilled prize rolls into next month's pool.
After every round you get a unique claim code like K9XF-3MN7-LP4Z that only you see (and the server records). It's auto-saved in your browser. If you finish top 3, you enter that code on the Claim Monthly Prize page to verify it was actually you. Names on the public Past Winners page are partially obfuscated (e.g. Joh***oe) so impersonators have nothing to latch onto. No code = no payout.
If you used the same browser/device for your winning run, the Claim Monthly Prize page lists all codes saved on this device. If you cleared your browser or switched devices, contact hello@gkall.online with the exact details of your winning run (name, score, time, day) — we can verify against the database.
Winners submit their Tron (TRC20) USDT wallet via the Claim page. Each claim is reviewed manually by the operator and paid from the sponsorship pool. No private keys are held on the server — payouts are not automatic, but they are real.
Switching tabs or applications, opening developer tools, attempting to copy/paste, right-clicking, or answering implausibly fast (under 1.5s) on hard questions. Triggering any of these forfeits the round.
The site avoids questions you've already seen on this device. Pool currently contains 200+ items across four difficulty tiers. Once you exhaust the unseen pool, repeats may appear.
No. The leaderboard takes a display name only. Claims require a wallet address and optional contact.
Sponsorship donations to the TRC20 wallet on the Sponsor page. The pool is finite and shared across winners. If donations run low, claims queue until refilled.
No. Playing is free. You only ever receive funds — never spend them — for completed wins.
Tron USDT transfers cost a fraction of a cent vs. several dollars on Ethereum. More of every donation reaches winners.
