Learn from a sample situation

r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Focus on why the action is allowed, not only its outcome. Read the matching step again.

A useful caution

An inequality specifies order, not an exact difference. A different version of the game may use a different rule. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
