Frequently Asked Questions

We do, by hand, in plain JavaScript. No game engine, no third-party library, no build step. The site's entire script fits in a single readable file.

Yes. Each one is drawn fresh for every game and checked before it is shown: the maze is a spanning tree, the pipe grid starts from a solved network, the flood grid is tested by a solver. Nothing that requires guessing, nothing that is unsolvable.

Your decision about the cookie categories, and, if you accepted the “preferences” category, your best scores, your challenge streak, and your settings. None of it ever leaves your browser.

All four games work exactly the same, daily challenge included. The only difference: no best score is kept from one visit to the next, and the streak starts over from zero.

Open “Manage my choices” at the bottom of any page and uncheck “Preferences”. Best scores, streak, and settings are erased on the spot.

Because it isn't drawn at random: it is computed from the date. The same date gives the same seed, the same seed gives the same puzzle, on any device. No network request is needed.

Completing the daily challenge in at least one of the four games. Completing all four on the same day doesn't count four times: the streak is measured in days, not games. It breaks if a whole day passes without a single win.

A lost game, or a second win on the same day, adds nothing: the daily challenge can be completed once per day per game. The game tells you so plainly.

You'll get the challenge for whatever date your device shows. Since nothing is checked server-side, there being no server, the streak is a commitment to yourself, not a ranking to defend.

We detect them and record them in your consent record. Since no optional category is on by default, a GPC signal changes nothing about what the site does today: there is nothing to turn off.

None today. If that were to change, the advertising disclosure page already describes the rules that would apply, and advertising cookies would remain conditional on your explicit consent.

Once the page has loaded, yes: nothing more is requested from the network. We don't install a service worker, so a full reload requires a connection.

Yes, all four games included. The accessibility page lists the keys for each game, one by one.
