We loved Tipover from Thinkfun, and Rush Hour is another great game from the same company. With lots of cards with suggested layouts you can set yourself challenges, or challenge a friend. Manoeuvre the red car out of the traffic jam: the cards are graded from easy to hard so this is a good game for age 8 to adult. It comes in a neat bag and makes a great game to travel with too.
The Rush Hour Game costs £12.99 and is also available in a junior version.
