One quick check so this solve can be ranked:
Open this shared VariantDoku puzzle.
Puzzle ID: daily
Keyboard: digits · arrows (⇧ extends) · hold ⇧ for corner marks, ⌘/Ctrl for center marks, Ctrl ⇧ for colors · Z digit · C center · X corner · V color · ⌫ erase
No time pressure. Take as long as you like: the clock starts when you tap OK and only counts toward today's leaderboard, where your first attempt is ranked unless you use Check, as in the app.
This daily has finished. Play it at your own pace: its leaderboard has closed, so this solve isn't ranked, and Check shows mistakes right away.
Clean first solves on iPhone, iPad, Android and the web. The clock only counts on this page, so there's no rush.

Hints
VariantDoku's hints read your pencil marks and walk you through the next deduction step by step. Get the app — it's free — and open this puzzle there.
More puzzles in the app, from 4×4 to 9×9.
Check
Check shows wrong digits and centre marks that rule out the answer. A checked solve isn't ranked on today's leaderboard — the same rule as in the app.
Daily Puzzle
A new daily is out. You can still finish this one, but it won't be ranked.
Restart
This removes every digit, mark and colour. The clock keeps running.
