Fun Brain Teasers For Teenagers: Arrow Number Puzzles - Paperback

by Marcus White (Author)

Arrow - Number is a logic puzzle published by Nikoli. The aim is to blacken some cells according to the following rules: - Black cells must not be orthogonally connected. - A cell with a number may be blacken. - All the white cells must form an orthogonally continuous area. - A cell containing a number and an arrow represents how many black cells are in the row or column pointed at by the arrow. - Numbered cells must be painted black if they contain false clues, but numbered cells painted black do not necessarily contain false clues.
