Size It Up Daily

One puzzle a day, five rounds, the same for everyone, generated from the date alone — so no two players ever see a different set and reloading cannot reroll you into an easier one. Below is how a daily is built, and what today's numbers are.

The last 30 days

Past dailies are not individually archived any more — the site keeps one puzzle per day and one page to explain it. Want to keep playing right now? Unlimited mode never runs out.

How a daily is built

Each day is a deterministic sequence of five rounds: a warm-up with a modest size ratio, a normal round, a cross-category surprise, a hard round with a ratio above 4×, and a finisher. The reference object is always the larger of the two — the player grows the unknown shape rather than shrinking a known one — and no object appears twice in the same day. Because the sequence comes from the date, reloading cannot reroll into an easier set, and two players comparing scores are always comparing the same puzzles.
