Rules
Slitherlink is played on a rectangular lattice of dots. Some of the squares formed by the dots have numbers inside them. The objective is to connect horizontally and vertically adjacent dots so that the lines form a simple loop with no loose ends. In addition, the number inside a square represents how many of its four sides are segments in the loop.
Other types of planar graphs can be used in lieu of the standard grid, with varying numbers of edges per vertex or vertices per polygon. These patterns include snowflake, Penrose, Laves and Altair tilings. These add complexity by varying the number of possible paths from an intersection, and/or the number of sides to each polygon; but similar rules apply to their solution.

Famous quotes containing the word rules:
“[O]ur rules can have authority over such natural rights only as we have submitted to them. The rights of conscience we never submitted, we could not submit. We are answerable for them to our God.”
—Thomas Jefferson (1743–1826)
“Playing games with agreed upon rules helps children learn to live by rules, establish the delicate balance between competition and cooperation, between fair play and justice and exploitation and abuse of these for personal gain. It helps them learn to manage the warmth of winning and the hurt of losing; it helps them to believe that there will be another chance to win the next time.”
—James P. Comer (20th century)
“A scholar, in his Segmenta, left a note,
As follows, “The Ruler of Reality,
If more unreal than New Haven, is not
A real ruler, but rules what is unreal.””
—Wallace Stevens (1879–1955)
