Santa’s nine reindeer (Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen and Rudolph) have their own stables. Use these clues to find out which stable each reindeer is in. • Prancer is next to Comet. • Vixen’s stable number is half Dasher’s stable number. • The red-nosed reindeer is in the middle stable. • The three reindeer with the same initial are next to each other. • Comet and Cupid are as far apart as possible. • Donner is next to Rudolph.

Intermediate

Santa's nine reindeer ( Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen and Rudolph) will play their favourite game (stable tennis!) and play each other once to see who is the North Pole champion. How many games will be played? What if there were 100 reindeer?
