Not necessarily. Easy Akari puzzles (7×7) are simpler than standard Sudoku because the rules are more intuitive. Hard Akari puzzles (12×12) can be as challenging as expert Sudoku. The difficulty depends on the puzzle, not the game type.
Partially. Both use logical deduction and constraint satisfaction, so the general mindset transfers. However, Akari requires spatial reasoning (tracking lines of sight) which Sudoku does not. Sudoku players will pick up Akari quickly but still need to develop spatial intuition.
Akari is generally easier for beginners because the visual feedback (light spreading) makes progress tangible. Sudoku requires comfort with numbers and scanning patterns that take practice to develop. Try GridPaw's Easy 7×7 puzzles to start.
Both engage logical reasoning, but Akari leans more on spatial processing (visualizing light paths) while Sudoku leans on working memory (tracking which numbers are possible). They complement each other well as cross-training.
