Stage 4:
Edsbyn to Ånge (90 miles)
Competitors will notice especially over this long stage that muggle settlements are starting to become more sparse the further north they travel. Ånge is the largest settlement in the municipality of the same name, with 3,000 muggles living there. The sparse population gives the area an average of just 3.5 people per square kilometre of land, which is good news as there are fewer muggles around to notice the broom racers whizzing over their heads!
Avoid earning a time penalty in the race by completing the challenges below.
Time
Challenge: This Christmas tree is decorated with 4 coloured chains of 7
lights each. Some lights already have numbers in them - your job is to fill
the remaining lights with numbers so that each chain contains 7 different numbers.
Also any straight line of lights (horizontal or diagonal in parallel with the
sides of the tree) should only contain one of each number. Score 15 seconds
for each correctly placed number to fill the remaining 18 bulbs.

Bonus
Time Challenge: Each of these cubes has a name from the Harry Potter world
in it. To find the name, you can start with any letter and move from letter
to letter by travelling to any adjacent letteracross, up and down, or
diagonally. You can use letters twice in the same name, but not in consecutive
moves - you must move on to a new square for each letter in the name - and you
might not need all of the letters in the cube to make your name. Here is an
example with the moves shown so you can see how it is done:
In
this example, start on the R on the bottom row, and follow the lines to the
N in the top right to spell "Remus Lupin."
