Best Logic Puzzle Apps for Adults (Free and Paid)
The best logic puzzle apps for adults depend on which kind of logic you enjoy: Simon Tatham's Portable Puzzle Collection for a free, ad-free mix of classics, Good Sudoku for number logic, LinkedIn's daily games and NYT Games for short daily puzzles, and Baba Is You or Euclidea when you want something deeper. Below they're compared by puzzle type, ads and price, with separate free picks for iPhone and Android.
If you're not sure whether you're better at number logic, patterns or word logic, that's the first thing to figure out, and IQ Tester shows you which reasoning skill is your weak spot: Find my weak spots.
How we picked
We didn't rank apps by how many stars they have. We picked using four questions:
- Is the logic real? Every puzzle should be solvable by reasoning alone, no guessing.
- Does it scale? Good apps go from gentle to brutal.
- How bad are the ads? An ad after every puzzle ruins focus.
- Is the price fair? One-time purchase, a small subscription, or truly free.
Prices, ad setups and features change often, so check the App Store or Google Play listing before you pay. Treat this list as a starting point, not a final word.
Best for logic grids
Logic grids are the "five people, five houses, ten clues" puzzles. They're the purest test of careful elimination.
Puzzle Baron's logic puzzles
Puzzle Baron runs a long-standing website of logic grid puzzles at different sizes and difficulties. It works in a phone browser, so there's no app to install. Great if you want endless grids.
Paper-and-phone method
Honestly, some of the best logic grid puzzles are free online or in holiday puzzle collections. Our Christmas logic puzzles with answers are a quick way to see if you like the format before you commit to an app.
What to look for in a logic grid puzzle app
- Auto-fill of X marks once you place a yes (you'll want to turn this off when you get good)
- Clue checking, so you can mark used clues
- Undo, because everyone makes a wrong mark eventually
Best for number logic (sudoku, kakuro)
Good Sudoku
Made by designer Zach Gage, Good Sudoku is built around teaching techniques instead of just throwing grids at you. It's a favorite for people who want to get better at sudoku, not just play it.
Sudoku.com
A huge, polished sudoku app from Easybrain with daily challenges and events. The free version has ads. If ads bother you, check the paid option.
Kakuro, KenKen and killer sudoku
These mix sudoku-style logic with addition. Search your app store for "kakuro" or "killer sudoku" and pick one with clear difficulty levels and a fair ad setup. Kakuro is a great next step once regular sudoku feels too easy.
Best for pattern and IQ-style puzzles
Pattern puzzles train the same skills as matrix and series questions on IQ tests.
LinkedIn games (Queens, Tango, Zip)
LinkedIn added short daily logic games, and Queens in particular is a clever pattern-and-constraint puzzle. Free with an account, and you get one per day so it never eats your evening.
NYT Games
Connections, Wordle and the Mini are free to play on the web, and a subscription unlocks the full set and archives. Connections is basically a verbal pattern puzzle.
Euclidea
Geometry construction puzzles: build shapes using only a virtual compass and straightedge. It's slow, satisfying, and very different from grid puzzles.
Baba Is You
Not an "app" so much as a full game, but its mobile version is one of the smartest logic puzzles ever made. You win by rewriting the rules of each level.
Here's the honest limit of apps: they tell you whether you solved a puzzle, not which kind of reasoning is actually your weakest. If you only play sudoku because you're good at it, your pattern and verbal logic never improve. IQ Tester checks number series, verbal analogy, logic and pattern side by side and shows your category strengths. Find my weak spots

How to get better at logic puzzles faster
Downloading the app is step one. Getting good is a different thing.
- Learn techniques, don't just grind. In sudoku, learning one technique (like "naked pairs") is worth more than 50 easy puzzles.
- Stay at the edge. Play at a level where you solve about 70% of puzzles. Too easy is boring, too hard is quitting.
- Mix puzzle types. If you only play one type, you only get better at that one type. Rotate grids, numbers and patterns.
- Review your mistakes. When you get stuck, figure out the exact clue you missed.
- Do it daily, briefly. Ten minutes a day beats a two-hour weekend binge.
