Categories
Find games by how they are solved
A game can belong to several categories. Each family explains the mechanics you will find and the mental processes involved while solving. The cognitive skills listed describe the mental processes each puzzle family engages during play; they are not a promise of clinical improvement or transfer to other tasks.
Numbers & arithmetic
Deduction with digits, sums, sequences and numerical constraints.
You will find: sums and combinations · sequences and inequalities · number placement
Engages: mental arithmetic · working memory · deductive reasoning
Cognitive challenge: They engage the simultaneous handling of quantities and constraints, alternating calculation, comparison and logical elimination.
44 games · Sudoku · Nonogram · Kakuro
Grids & regions
Divide, group or reason about areas of a grid.
You will find: area division · sizes and shapes · constraints between regions
Engages: visual segmentation · spatial reasoning · constraint planning
Cognitive challenge: They require moving continuously between individual cells and the global board structure while organizing information by zones.
54 games · Sudoku · Norinori · LITS
Paths & connections
Join points, build networks or find valid routes.
You will find: joining points or islands · building networks · finding routes
Engages: sequential planning · relational reasoning · global-local thinking
Cognitive challenge: They make you think several steps ahead and check how a local connection changes the options available across the board.
18 games · Stitches · Slant · Train Tracks
Loops
Draw a closed circuit while satisfying local clues.
You will find: closed circuits · edge clues · branch-free routes
Engages: conditional reasoning · anticipation · inconsistency detection
Cognitive challenge: They exercise consequence checking within the puzzle: a line that looks correct can invalidate the circuit many steps later.
8 games · Castle Wall · Balance Loop · Masyu
Shading
Decide which cells to shade, block or leave empty.
You will find: black and white cells · clue-driven patterns · area separation
Engages: selective attention · binary reasoning · pattern recognition
Cognitive challenge: They reward precise board reading because small state changes quickly alter neighboring constraints.
18 games · Nonogram · Norinori · LITS
Placement
Place pieces, objects or marks without breaking constraints.
You will find: conflict-free pieces or objects · distribution under constraints · coverage and exclusion
Engages: alternative evaluation · spatial planning · constraint memory
Cognitive challenge: They engage comparison of possible positions and the ability to retain constraints while planning later placements.
14 games · Dominosa · Magnets · Minesweeper
Patterns & deduction
Recognize relationships, repetitions and logical structures.
You will find: repetitions and sequences · symmetries and relationships · implicit logical rules
Engages: pattern recognition · cognitive flexibility · hypothesis formation and rejection
Cognitive challenge: They encourage changing strategy when a hypothesis stops fitting and looking for relationships that are not always obvious at first glance.
20 games · Nonogram · Norinori · Str8ts
Spatial logic
Rotate, slide, connect or interpret positions on the board.
You will find: sliding and rotation · piece orientation · moves and positions
Engages: spatial visualization · mental rotation · move planning
Cognitive challenge: They engage mental representation of positions and transformations, especially when several moves must be anticipated.
13 games · LITS · Pipelink · Shakashaka
Sudoku family
Classic Sudoku and variants with additional rules.
You will find: classic and mini Sudoku · cage or sum variants · diagonals and special regions
Engages: attentional scanning · working memory · elimination-based deduction
Cognitive challenge: They require systematic review of rows, columns and regions while keeping candidates and eliminations in mind without losing the overall picture.

Strategy vs CPU
Play against the CPU
Competitive games kept separate from single-solution puzzles. Here it is not enough to satisfy constraints: you must respond to an opponent, create threats and adapt the plan turn by turn.
You will find: territory control · formation and capture · connection and blocking
Engages: multi-turn planning · alternative evaluation · anticipation de respuestas
Cognitive challenge: They add strategic uncertainty: every decision is also judged against the best response the CPU might find.
