How to interact with the game

An example before you play
On one puzzle in this collection, row 1, column 2 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Apply the same reasoning to the position in your own round. Look for the relevant detail.
Pay attention to this rule
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. 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.
