The House That Jack Built

The House That Jack Built is an educational game for practising maths. The player's task is to help Jack build his house. Questions are given and for each correct answer Jack adds one more row of bricks to the house until the construction is complete. If an answer is wrong some bricks will instead fall off. The game can be played with either multiplication or division problems and the difficulty can be set from one to nine. The game is on time and the aim is to complete the house as quickly as possible.
