杀手应用中要寻找什么？
The most important feature for learning is notes and pencil marks. Killer Sudoku candidate tracking is significantly more complex than classic Sudoku, and any app without a good notes mode forces you to either memorise or abandon proper technique.
A hint system that reveals a specific cell is more educational than one that only highlights errors. Unlimited undo is essential for exploring logical branches without fear of ruining your progress.
纸质与数字
Paper Killer Sudoku requires careful notation - Many players use small letters to mark cage candidate sets in cell corners. Digital tools make this effortless. For learning, digital is faster. For competition preparation, occasional paper solving builds the raw visual scanning skill that digital tools can obscure.
