Choosing and moving on screen
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
Follow the example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Your next round may have a different position, so inspect it before acting. Notice the change in the playing area.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. 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.
