An example before you play
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Use the example as a guide rather than a substitute for reading your board. Verify the rule before continuing.
One detail worth checking
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. 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.
