Terms of entryand prize terms

Edge Cases, operated by to be announced.

A free puzzle competition of skill. No purchase, deposit or wager is required, and none is possible. Nothing on this site is gambling.

You must be 18 or over. One account per person.

The competition is not available to residents of, or persons in, countries or regions subject to comprehensive sanctions, as published by the UN, the EU, the UK and the US (see section 6, Winner checks).

The organiser, anyone who helped build or test the case, and the sponsor’s staff involved with the competition may play, but cannot win the prize.

The race opens for everyone at Saturday 24 October 2026, 12:00 UTC. The winner is the first entrant to file a correct determination for exhibit 10, by server time to the second. Ties are broken by the fewest wrong submissions.

The official race closes 7 days after the start (Saturday 31 October 2026, 12:00 UTC). The case stays playable after that, but only finishes before the close count. Second and third place are recorded the same way.

Prize: to be announced, provided by to be announced.

The prize is paid in USDT to a wallet address in the winner’s own name, on a network agreed with the winner, within 30 days of successful verification. There is no cash alternative. Taxes and fees on the winner’s side are the winner’s responsibility.

Before payment, the winner must verify their identity and age, confirm their eligibility and residence, and pass a sanctions screen. If they can’t or won’t within 14 days, the prize passes to the next eligible finisher.

No sharing answers or accounts. No automated submission tools. No attacking the site. The organiser may disqualify entrants for breaches, including on evidence from per-entrant answer data. Disqualification decisions are final.

The organiser may postpone, pause or cancel the race for reasons outside its control, for example a technical failure that makes the race unfair, with notice on this site.

The site is provided as is. Nothing in these terms excludes liability that cannot be excluded by law.

The winner’s handle, not their real name, is published on the site and in posts about the race. Anything more is published only with their consent.
