The best logic games do not all test the same mental muscle. Some ask you to plan several moves ahead, some reward careful visual scanning, and others turn numbers into a compact reasoning challenge. This ranked guide brings together eight free picks from the Mentometry Brain Games directory, from maze-solving adventures to Sudoku and investigation puzzles.
- The list follows the directory’s rating order, based on a Bayesian blend of store ratings and Mentometry player votes.
- 20 Small Mazes leads the ranking with a 5.0/5 rating from 9,547 votes.
- Choose Sokoban and maze games for spatial planning, Sudoku and number grids for structured deduction, or investigation puzzles for attention and clue handling.
- Every game listed here is free, but platform availability varies from Steam to Google Play and the App Store.
How We Ranked These Free Logic Games
This is a buyer’s-guide style ranking, but there is no purchase price to compare: every game below is listed as free. The order is the directory’s rating order, produced through a Bayesian blend of store ratings and Mentometry player votes. That approach gives both the displayed score and the number of votes context, rather than treating a small rating sample as automatically equal to a much larger one.
The ranking is not a scientific league table for intelligence, and it does not establish that any game improves general reasoning ability. Instead, use it as a practical starting point. The skill tags supplied for each listing show the kind of play involved, while the platform and vote count help you judge whether a game fits your setup and how much player feedback is available.
Logic puzzles can involve skills such as planning, attention, spatial processing and numerical reasoning. Performance on a game is still performance on that game; it should not be treated as proof of broader cognitive improvement or as a medical intervention.
Top-Rated Logic Picks
1. 20 Small Mazes
20 Small Mazes presents twenty maze puzzles in a compact adventure and point-and-click package. The core task is straightforward: work out a route through each maze, using visual information and logical choices to reach the solution. Its listed skill tags are Logic & Reasoning and Spatial & Visual.
This is a strong fit for players who enjoy short, self-contained challenges and want a clear spatial puzzle rather than a number grid. It has a 5.0/5 rating from 9,547 votes, giving the listing a notably large feedback base. The limitation is platform choice: it is listed for Steam only, so it is not a pick for someone specifically seeking a mobile game.
2. Sudoku – Classic Number Puzzle
Sudoku – Classic Number Puzzle is built around the familiar Sudoku format: use logic and numbers to complete a grid while respecting its constraints. The supplied skill tags are Logic & Reasoning and Math & Numeracy, making it a natural match for players who prefer structured deduction over visual navigation.
It suits people who want a focused number puzzle on Google Play, particularly those who already enjoy the Sudoku format. The listing carries a 5.0/5 rating from 596 votes. That is a positive result, but its vote count is much smaller than the leader’s, so the rating comes with a narrower base of player feedback.
3. Handshakes
Handshakes is a Sokoban and block-pushing puzzle in which you guide two hands through the levels. The supplied description frames it as a simple but tricky challenge, while the skill tags point to Logic & Reasoning, Spatial & Visual and Planning & Strategy.
Choose it if you like puzzles where an early move can shape the rest of the level and where planning matters as much as immediate problem-solving. It is free on Steam and has a 5.0/5 rating from 2,941 votes. The limitation is genre specificity: block-pushing puzzles can be demanding if you prefer quick answers or more open-ended exploration.
For a useful first session, play one maze, one Sudoku grid and one block-pushing puzzle. Notice whether you prefer scanning space, eliminating number possibilities or planning a sequence of moves. That preference is often more useful than chasing a generic “hardest” label.
Math and Number-Grid Challenges
4. Math Puzzle Games – Crossmath®
Math Puzzle Games – Crossmath® combines Math & Numeracy with Logic & Reasoning. Its listing places it in the math and numbers category and describes a crossmath-style puzzle, so it is aimed at players who enjoy fitting numerical relationships into a broader puzzle structure.
This is the highest-vote game in the list by a wide margin, with a 4.9/5 rating from 258,073 votes. That makes it an appealing choice for players who want extensive user feedback behind a strong rating. It is listed for the App Store only, which is its clearest practical limitation.
5. Sudoku – Daily Puzzles
Sudoku – Daily Puzzles offers another route into the classic Sudoku format: fill numbers so each row, column and region contains each number once. Its skill tags are Logic & Reasoning and Math & Numeracy, so the focus is careful deduction rather than speed alone.
It suits regular Sudoku players who like a recurring puzzle routine and want an App Store option. The listing has a 4.9/5 rating from 6,749 votes, a substantial feedback base for this ranking. The limitation is that it remains a familiar, narrowly defined puzzle type; players looking for mazes, stories or spatial movement may find less variety here.
6. Pawdoku-Logic Puzzle
Pawdoku-Logic Puzzle is listed as a logic puzzle built around a Queens-style board and a single-solution premise. Its only supplied skill tag is Logic & Reasoning, making it the most focused pick in the guide for players who want a pure logic challenge without a separate math tag.
The game is free on the App Store and holds a 4.9/5 rating from 5,261 votes. It may suit players who enjoy minimalist board problems and the satisfaction of narrowing a puzzle to one solution. The limitation is that the available information describes a specific puzzle format, so it may not offer the numerical variety of Sudoku or crossmath games.
7. Math Grid – Number Puzzle Game
Math Grid – Number Puzzle Game combines Math & Numeracy and Logic & Reasoning. The listing describes a number puzzle that combines the challenge of crossword puzzles with math problems, giving it a grid-based identity for players who like both word-puzzle structure and numerical work.
This App Store game is free and has a 4.9/5 rating from 5,232 votes. It is a good fit for players who want mathematics presented as a grid rather than a conventional Sudoku board. Its limitation is also its defining feature: the math-and-grid format will not suit players who prefer visual mazes or story-led deduction.
Pick one number-grid game and set yourself a simple goal: complete a single puzzle while writing down no guesses. Concentrate on what the grid tells you, then stop when the puzzle is finished rather than turning the session into a marathon.

Investigation and Attention Puzzles
8. Griddle – Logic Game
Griddle – Logic Game is an adventure and point-and-click investigation puzzle. Its listing describes hidden clues and mysterious cases, while the supplied skill tags are Logic & Reasoning and Attention & Focus. That combination makes it a natural choice for players who enjoy examining information and connecting clues rather than only manipulating a board.
It is free on the App Store and has a 4.9/5 rating from 1,281 votes. Choose it for a more investigative atmosphere within the directory’s logic-puzzle selection. The limitation is the smallest vote count among the games listed here, so its rating has less player feedback behind it than the higher-volume entries.
How to Choose Your Best Match
The ranking tells you which games sit highest in the directory, but your ideal pick depends on the kind of reasoning you enjoy. A player who finds number grids satisfying may have a better time with Sudoku or Crossmath than with a maze, even if the maze ranks higher. Likewise, someone who enjoys planning several moves ahead may prefer Handshakes to a faster, more familiar puzzle format.
| If you want… | Start with… | Why it fits |
|---|---|---|
| Spatial route-finding | 20 Small Mazes | Its focus is maze-solving with Logic & Reasoning and Spatial & Visual tags. |
| Classic number deduction | Sudoku – Classic Number Puzzle | It pairs the Sudoku format with Logic & Reasoning and Math & Numeracy. |

- All eight games are listed as free.
- The selection covers spatial, numerical, strategic and investigative puzzle styles.

A high rating tells you that a game is well regarded in the supplied directory data. It does not show that the game raises intelligence, prevents dementia or treats a health condition. Think of these titles as structured entertainment with different reasoning demands.
How These Skills Connect to Mentometry
The directory’s skill tags are useful because they describe different kinds of challenge rather than treating every puzzle as interchangeable. Spatial games ask you to inspect layouts and routes. Number games ask you to track constraints and relationships. Planning games make you consider consequences, while attention-focused games reward careful observation of details.
Mentometry’s free games offer short ways to practise related task types. In Quick Math, an equation appears with an answer already filled in, and you quickly judge whether it is correct or incorrect before time runs out. That makes it a compact choice for players who want a timed Math & Numeracy decision task alongside the longer number puzzles in this guide.
Odd One Out asks you to inspect a group of shapes and tap the item that differs from all the rest. It pairs naturally with the visual scanning side of maze and investigation play, although it is a distinct task rather than a replacement for those games.
The practical approach is to rotate formats instead of repeating one puzzle endlessly. Try a number task when you want calculation and rule-checking, a visual task when you want comparison, and a listed game when you want a longer puzzle structure. Keep the goal modest: explore which challenges you find engaging and which ones make you think carefully.
