Sudecku vs Infinite Numbers

Sudecku is Sudoku with a deck of cards in your hand. The grid is the same 9×9 you already know, but you just fill it differently. Every number you place is a card you've drawn. Alongside the numbers there are power cards that can fill a stubborn cell, check your work, or reshuffle your hand when you're stuck. Sudoku with card strategy! What's in it: - A new puzzle every day, at several difficulty levels - Number and power cards you unlock over time and build into your own deck - High scores that actually unlock things, so a good run gets you stronger cards - A clean layout for iPhone and iPad with nothing in the way of the puzzle I started this as a small experiment: what if Sudoku had a little risk in it? It turned out to be more fun than expected, and it's been shaped slowly, one piece at a time! If you like Sudoku but wish it pushed back a bit more, or you like card games and want something quieter, give it a try.

∞ Numbers is a quiet offline game about integer sequences. Guess integer sequences drawn from the On-Line Encyclopedia of Integer Sequences (OEIS). Your job is to guess the next number. How it plays. Tap a row, look at the first few terms, type your guess on the numpad. When you've had enough, tap Reveal to see the real name of the sequence and references to OEIS and Wikipedia. Made for calm play. No ads. No accounts. No in-app purchases. No ranking or leaderboards. The app never touches the network after install — every sequence is bundled with the app, and the only "internet" is the moment you tap a reference link to open a browser. Designed to disappear. No analytics, no notifications, no permission prompts. Nothing asks for your location, contacts, microphone, camera, or anything else. The only data stored anywhere is the in-progress state of your own game, kept locally on your device. You can wipe it any time from iOS Settings. For who. Math hobbyists, puzzle fans, kids and parents looking for a screen-time option that isn't loud, and anyone who's ever read an OEIS page for fun.
