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. Each collection features puzzles made by various authors that are now familiar names to those who follow the channel. Authors like Phistomefel, Clover, Sam Cappleman-Lynes, Christoph Seeliger, Richard Stolk, jovi_al, Qodec, Prasanna Seshadri and of course, Simon and Mark! Downloading Cracking the Cryptic will give you access to our first free collection – a variety pack by Prasanna Seshadri featuring 7 puzzles inspired from our previous Sudoku apps; Sandwich, Classic, Chess, Thermo, Miracle, Killer and Arrow Sudoku. We also have purchasable packs designed for all skill levels and featuring many unique variants not seen previously. We’ll be releasing more free and paid packs in the future so keep an eye on the app for more Sudoku content from Cracking The Cryptic!

Verdict
The clearest difference is ads: Cracking the Cryptic at none against Flow Free's shown. Cracking the Cryptic also leads on update cadence (every 3 weeks vs every 5 months). Flow Free's advantage is rating (4.7 vs 4.4) and ratings volume (5.2K vs 208). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Flow Free sells 12 one-off in-app purchases and Cracking the Cryptic sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Flow Free holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Flow Free has 5.2K ratings behind it against 208, so its average is the more settled of the two. Written reviews point the same way: 82% of Flow Free's written reviews are positive against 72% of Cracking the Cryptic's.
Flow Free ships an update every 5 months, Cracking the Cryptic every 3 weeks. The most recent releases landed on September 25, 2026 and September 26, 2026 respectively.
