OUR NEWEST PACK – CLASSIC VOLUME #2! Classic sudoku is where it all began, and there is still lots of skill to be deployed to solve classic puzzles, and new techniques to be explored. Nikoli, the Japanese puzzle house, named and popularised sudoku from 1984, and we have commissioned 20 puzzles from them for this Classic Sudoku 2 app. We have also created 20 ourselves, and sourced 20 more from Sam Cappleman-Lynes, the brilliant British sudoku expert. The result is a wonderful 60-puzzle pack which will delight and challenge you. -------------------- Welcome to the brand new Sudoku app from the most popular Sudoku channel, Cracking The Cryptic. Unlike other Sudoku apps, we feature handcrafted and curated puzzles from the world’s best Sudoku constructors.

NO_OP_
Read full descriptionHide full description
NO_OP_ is a quiet puzzle game about ones and zeroes. The screen is a field of digits. Drag across neighbouring cells that share the same digit to build a sled, then lift your finger and it clears. The cells above fall in to fill the gap. That is the whole game. There is no timer, no move limit, and no way to lose. Dragging onto a digit that doesn't match is simply ignored, never punished. Fingers are imprecise, and the game never treats that as a mistake. Put it down mid-run and it will be exactly where you left it. THREE WAYS TO PLAY ENDLESS is a minimum sled of two, and it never moves. No ending, no score to chase. Somewhere to put your hands. ASCENT starts the minimum sled at three and climbs by one every forty cells you clear. That is the entire difficulty system. At three you glance, at six you scan, at nine you plan a route before touching the screen. DAILY is a single board seeded from the date, so everyone plays the identical one. Nothing refills, so the board only shrinks. Clear as much as you can, share a picture of what you left behind, and come back tomorrow. TWO COLOURS, ALWAYS Every theme is exactly a background and an ink: light, dark, terminal green, amber, and DOS blue. A selected cell is a straight inversion with square corners and no gap, so a run merges into one solid shape. There is no third colour anywhere, including the icon. IT SHOULD FEEL LIKE SOMETHING A tick as each cell joins the sled, a heavier one when it clears, and nothing at all when a drag drifts onto a digit that doesn't match. The haptics are the point, not the polish. NOTHING LEAVES YOUR DEVICE No accounts. No analytics. No ads. No crash reporting. No network calls of any kind. It works in airplane mode, permanently. The daily board isn't handed out by a server. It's arithmetic from the date that happens to agree across every device. A no-op is the instruction that does nothing. The trailing underscore is a terminal cursor.

Verdict
The clearest difference is in-app purchases: NO_OP_ at none against Cracking the Cryptic's 13. Cracking the Cryptic's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price and ads there is nothing between them.
