Why Point de Genie exists

We are a very small team, and we love games that fit in a single rule and can be replayed forever. Point de Genie brings four of them together: a maze, a pipe network, a memory game, and a flood puzzle. We wrote them ourselves, in plain JavaScript, with no game engine and no framework.

What we like about these four is that none of them is a hand-drawn level: they are all generated. The fun comes from a solver that guarantees there is a solution, and a generator that never repeats itself.

What we built

Four games, each with its own page, illustrated rules, and best scores. The whole site is one stylesheet and one script file. There is no build step, because none is needed.

Each game's logic is kept separate from its display. That lets us test the rules without a browser: the maze generator, the pipe scrambler, the flood solver, and the Sequence pattern all run in our test suite on every change.

Daily challenge

Each game draws a puzzle from the date. Not from a server, not from a random draw: from a function that turns the date into a number, and that number into a maze, a grid, or a pattern. Two people on opposite sides of the country open the same page and face the same puzzle, without a single byte passing between them.

We care about this for a specific reason. A daily challenge is usually the excuse a site gives itself to open an account, send a notification, and build a leaderboard. Here, the date is enough. Your streak lives in your browser, is compared with no one, and if you lose it, you are the only one who knows.

What we deliberately don't do

• No accounts. There is nothing to create, so nothing to lose, nothing to resell, nothing to leak.
• No analytics. We don't know how many people are reading this sentence, and we're fine with that.
• No sound. Sequence, our memory game, is played by eye and by written announcement, not by ear.
• No advertising today. If that ever changes, the advertising disclosure already describes the rules we hold ourselves to.
• No online leaderboards. Your best scores and your streak are in your browser; they have no exchange value and no recipient.
• No notifications, no reminders, no emails telling you your streak is in danger.

Two things we would do differently

Flood's target comes from a greedy solver, not an optimal one. It is always reachable, but it is not necessarily the absolute minimum number of moves—finding that minimum is a far more expensive problem to compute. We would rather show an honest, beatable target than an exact number the browser can't reach.

Your streak depends on your device's clock. Set it back a day and you will replay yesterday's challenge; set it forward and you will skip a day. We could check against a time server. We won't: it would be the site's first network request, and it would exist to keep an eye on someone who is only playing against themselves.
