ClueKeeper is a powerful platform for creating and playing clue hunts! What's a clue hunt? A clue hunt is a game in which the players solve clues that lead them from one to the next. The clues can be straightforward questions, physical challenges, clever puzzles or riddles, or whatever else the hunt creator can imagine. With the help of our friends from Zappar, we even support augmented reality clues! A hunt might send players searching around their local park, through the best-kept secret spots of their city, or even across state lines. ClueKeeper hunts provide a great way to have fun and explore your surroundings in a new and exciting way! Our app even works offline, allowing you to explore off-the-beaten path areas without a consistent cell connection. To get started, try out the sample hunt "Welcome to ClueKeeper"!

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 in-app purchases: ClueKeeper at none against Cracking the Cryptic's 13. Cracking the Cryptic's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (208 vs 20). On price, rating, review sentiment and ads 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. Cracking the Cryptic sells 13 one-off in-app purchases. ClueKeeper asks for nothing beyond the download.
ClueKeeper holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Cracking the Cryptic has 208 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 67% of ClueKeeper's written reviews are positive against 72% of Cracking the Cryptic's, so the app with the better star average is not the one people write more warmly about.
ClueKeeper ships an update every 3 months, Cracking the Cryptic every 3 weeks. The most recent releases landed on September 6, 2026 and September 21, 2026 respectively.
