Sudoku a Day is a free daily puzzle platform that delivers one handcrafted Sudoku puzzle every morning. Available as an iPhone app and through a clean web interface, it strips away the clutter of modern puzzle apps — no ads, no subscriptions, no timers, no pressure. Just a single 9×9 grid designed to give your brain a focused logic workout in a few quiet minutes. The service also offers free printable PDF packs and step-by-step strategy guides, making it a complete daily ritual rather than just another puzzle app.
A new handcrafted puzzle appears every morning, giving you a consistent daily habit without overwhelming choice. There's no backlog to manage, no endless menu of variants — just today's puzzle, ready when you are.
You can set your preferred challenge in the app's settings: Easy, Medium, Hard, Expert, and Master. This lets you start gently and progress as your logic skills sharpen, or jump straight to the deep end if you're already a seasoned solver.
Weekly puzzle packs are available in A4 and US Letter formats, including large-print options. This makes the game genuinely portable — print a pack for a flight, a waiting room, or a screen-free evening at home.
Step-by-step strategy guides cover everything from the basic rules to advanced solving techniques. The iPhone app also includes dark mode and saves your place, so you can pick up mid-puzzle without losing your thinking thread.
"No ads, no stress. Just good puzzles."
That quote from a daily solver captures the product's entire philosophy. Sudoku a Day deliberately refuses the common monetization patterns of mobile puzzle games — there are no banners, no video ads, no "watch to reveal a hint" interruptions. The interface is clean, the daily cadence is calming, and the difficulty scaling is honest. It's a rare example of a free puzzle service that treats your attention as something to respect, not harvest.
You value a single, well-crafted daily puzzle over a chaotic library of options, or if you've been hunting for a Sudoku app that won't nag you with ads and in-app purchases. It's also a strong fit if you prefer learning through structured guides rather than trial-and-error, or if you like having a printable option for offline solving. And if you're new to Sudoku entirely, the beginner tips and progressive difficulty levels make this one of the least intimidating entry points available.

The keyboard fell apart, stack it back together. Tetris meets QWERTY.t's Tetris, except the blocks are keys and every single one has exactly one home. Drop the A on the A. The Z on the Z. You get it. Miss the spot, and that key turns into a useless gray brick that just sits there, bothering you until you explode it. Stack them right and the keyboard lights up blue, row by row, until the whole thing is whole again. Stack them wrong long enough and the junk piles to the top and it's over.
