Can you get all twelve right?

Yes. Entering and playing cost nothing. No purchase, subscription, advert or review is needed, and none of them gives you an advantage.

Anyone who lives in one of the eligible countries and is 18 or older (in the United States, also the age of majority in their state: 19 in Alabama and Nebraska, 21 in Mississippi), except the organiser and his household. The eligible countries are Andorra, Australia, Austria, Belgium, Bulgaria, Czechia, Estonia, Finland, France, French Guiana, Germany, Guadeloupe, Hungary, Ireland, Japan, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Macau, Malaysia, Malta, Martinique, Mayotte, New Zealand, Norway, Poland, Réunion, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United States. Some of them may not be open to entries yet, for example while a translation of the rules is being checked: the join form shows which. You join and play on an internet connection in the country where you live: connections from elsewhere, or through a VPN or relay that ends elsewhere, are refused. One entry per person. What each country includes

By skill alone. Only a perfect run, all 12 right, can win. A question not answered within its 5 seconds (plus your connection allowance) counts as wrong. If several players have a perfect run, the shortest total answering time (measured by the server, minus each player’s connection allowance) wins. Each answer counts for at least the question’s reading time, so answering faster than anyone can read gains nothing. If they’re still level, the jackpot is shared equally.

The server is in the EU, so a question and your answer take longer to travel the further away you are. The server measures each player’s connection delay and makes up for it, up to a limit for each region: 150 milliseconds in Europe, 300 in the Americas, Mayotte and Réunion, and 400 in Asia and Oceania. How it works. The tournament is at 8 pm Central European Time, which is Monday morning in Asia and Oceania.

Then nobody wins that week, and the jackpot rolls over: US$100 is added for the next tournament, again and again, with no upper limit, until someone has a perfect run. After a win it starts again at US$100. Everyone still sees the ranking. The one exception is the last tournament, if the organiser ever ends them: see “Will it always roll over?” below.

When the lobby opens at 7:45 pm. Before that, the amount shown is the jackpot as it stands, and it can still change; from then on, it’s that tournament’s jackpot.

Yes. The tournament is organised by Andrei Tchernoivan (VAT number MT33118505), its only sponsor, who pays the jackpot. His full address is at the bottom of this page. Apple and Google are not sponsors and are not involved.

By bank transfer in US dollars from the organiser’s bank in Malta, to an account in the winner’s own name. The winner is told in the app when the tournament ends and claims the jackpot there within 14 days. The organiser then asks by email, never in the app, for bank details and, if needed, proof of age and of residence in the country the winner declared, and checks the winner against the EU and US sanctions lists and, for Swiss residents, the Swiss (SECO) lists. It’s paid within 30 days once the claim and eligibility are checked. The organiser pays his own bank’s fees; he does not pay fees charged by other banks, your bank’s conversion of US dollars into your currency, or any tax due. A jackpot not claimed in time goes to the next eligible player with a perfect run or, if there’s none, into the next jackpot.

A phone or computer with a current browser (not a private window), an internet connection in the country where you live, and a nickname. No account, nothing to install: you play in the web app at app.mnemocracy.com. The App Store and Google Play apps are coming soon.

Yes, each on their own phone with their own entry, and everyone sees the top ten afterwards. Helping each other during the game is against the rules, and taking part with more than one device, installation or nickname disqualifies all of that person’s entries. A connection takes a limited number of entries, so a big group on one Wi-Fi may find some joins refused.

If a technical problem, a Wikipedia outage or anything else outside the organiser’s control would make it unfair, the tournament may be postponed or cancelled, and the app says so. A postponed or cancelled tournament’s jackpot carries over unchanged. A question that turns out to be wrong or ambiguous is removed from everyone’s score.

For as long as the tournaments run. If the organiser ends them, he announces the last one in the app at least 4 weeks ahead. The last tournament has the same rules, except that if nobody has a perfect run, its jackpot is not paid.

The tournament keeps only what it and its statistics need, such as your nickname, the country you live in, your answers and times, and a code to count returning players, and deletes them 90 days after the tournament. After that only totals are kept, published without nicknames and never for a group of fewer than 5 players. Your IP address is used to check that you connect from the country you declared and is not stored. A winner’s claim details are kept longer, as the rules explain. Privacy notice
