Three fresh puzzles every day, a ranked Hard mode with its own leaderboard, and the Daily Triple for players who want a real fight.
Every day at midnight UTC, three brand-new puzzles unlock: one Easy, one Medium and one Hard. They are the same three puzzles for everyone in the world, so you can compare your time against anyone. Practice mode gives you the full toolset — undo, redo, pencil marks, candidate highlighting, check-cell and check-puzzle — so it is a comfortable place to learn rather than a test.
A calendar view tracks which days you have completed. Finishing a day keeps your streak alive; missing one resets it. Past days stay open, so you can go back and clear a puzzle you skipped — that fills the calendar square, though only same-day solves count toward the live leaderboard.
Ranked is the competitive version and it plays very differently. It is Hard difficulty only, you get exactly one attempt per day, and the assist tools are switched off — no undo, no redo, no candidate display, no check-cell or check-puzzle, and the solver refuses the puzzle outright. The clock starts the moment the board appears and cannot be paused.
Finish and your time goes on that day's leaderboard, which is kept for seven days. If you get stuck there is a Give Up button: it submits the attempt and closes out your day rather than leaving the run hanging. Because there is only one attempt, ranked rewards a clean first pass over a fast reckless one.
The Daily Triple is the elite event: three legs in a single sitting, drawn from the Extreme and Diabolical pools. Leg one is a Classic grid, leg two is Symmetric, leg three is a Shape puzzle. You take them one at a time — a leg must be finished or given up before the next unlocks — and all three must be played on the day they are issued.
All three legs feed one combined live leaderboard, with a crown on whoever holds first place. Unlike the ranked daily board, Daily Triple results are kept permanently, so the archive builds into a real record over time. Completion is confirmed by the server, not the browser, and the whole event rolls over strictly at UTC midnight with no grace period.
Every daily feature on the site keys off the same UTC date. At 00:00 UTC the practice trio, the ranked puzzle and all three Daily Triple legs change together — there is no staggered release and no grace window on either side. If you are mid-solve when the day turns, finish before midnight: the puzzle you are holding belongs to the day it was issued.
That also means the "best time" you are chasing on the leaderboard is always a same-day time. Depending on where you live, the reset may land in the middle of your afternoon rather than overnight — worth knowing before you start a ranked run twenty minutes before the hour.
Yes. All three practice puzzles, the ranked Hard puzzle and the three Daily Triple legs are identical for every player worldwide on a given date, which is what makes the leaderboards meaningful.
Practice puzzles can be replayed freely. Ranked and each Daily Triple leg allow exactly one attempt per day — giving up counts as your attempt.
The streak resets. Completing a past day from the calendar fills that square and counts toward your record, but it does not restore a broken streak.
Ranked, tournaments, duels and the Daily Triple all run with assist tools disabled so that every player is solving under identical constraints. Practice mode keeps the full toolset.
Ranked daily leaderboards are retained for seven days. Daily Triple results are kept permanently.
