The Daily Deal
— Klondike, and everybody gets this exact shuffle. New one at midnight.
— Klondike, and everybody gets this exact shuffle. New one at midnight.
One deal a day. Not a random one — the one. Every person who opens this page today gets the identical arrangement of cards, so a time actually means something.
The deal is generated from today's date, using a deterministic shuffle. There's no server dealing the cards out, and no database telling you which one to play. Everyone gets the same shuffle because everyone's calendar agrees — which is also why this page keeps working with the internet switched off.
Solve today's deal and your streak grows by one. Miss a day and it goes to zero. That's the whole mechanism, and it is a surprisingly effective piece of psychology — it costs nothing to start and it stings to lose.
Your streak lives on your own device. No account, no login, and nobody at this end knows whether you kept it.
Because it would be a lie. Every game here runs entirely inside your browser — which means any score that could be sent to a server could just as easily be invented. Every no-login leaderboard on the internet is topped by someone who opened the developer console, and we'd rather not pretend otherwise.
What you get instead is honest: your own record, and a result you can send to a friend who played the identical deal. That comparison is real, because you both had the same cards.
(A verified leaderboard is possible — the deal comes from a seed, so a solve could be proved by replaying the moves. It's a good idea, and it needs a server. Later.)
