Methodology

Every LESSGAME DAILY puzzle is generated deterministically from the current UTC date. This means that on any given day, every visitor around the world receives exactly the same challenge — with no server round-trip required.

Deterministic Seeding

Each game derives its daily answer from a seed built from the UTC date and the game's content index. A deterministic pseudo-random generator maps that seed to a specific item in the game's content list. Because the algorithm is deterministic, the same date always produces the same puzzle. There is no randomness that varies between players or sessions.

This approach lets us ship puzzles without a backend: the content lists are bundled with the app, and the daily selection happens client-side. It also means puzzles are reproducible — useful for sharing, archiving, and auditing.

UTC-Based Daily Challenges

The daily boundary is midnight Coordinated Universal Time (UTC). When UTC midnight passes, a new puzzle becomes available for every player worldwide, regardless of their local time zone. The countdown on the home page shows the time remaining until the next UTC midnight.

Using a single global boundary keeps the “everyone gets the same challenge” promise honest. No-one gets an early peek or a late disadvantage based on where they live.

Content Versioning

Each game records a content version alongside every saved result. If we ever correct a word, replace a melody, or fix a fact, the content version is bumped. This lets us distinguish results earned under different content sets, so historical statistics remain comparable and fair.

Archived puzzles are also keyed by date and content version, so you can revisit a past day and see exactly the challenge that was live at the time.
