Halloween is an annual celebration held on the 31st October, the eve of All Saints' Day. Typical festivities include trick or treating, pumpkin carving, dressing up and apple bobbing. Did you know that the first Jack O' Lanterns were carved from turnips and not pumpkins?
See if you can solve these four arithmagons.
The aim of an arithmagon is to work out which numbers go in the empty circles. The numbers in the square boxes are made by adding together the numbers in the circles either side. For example, if the number in the square box was 10 you could try 6 and 4, but the numbers must also add up on the other edges, making this more difficult than it first appears.
