Don't Wake Dad Game Was £22.99 Now £13.13 @ Amazon
Edit 07/11/15 - price dropped to £13.13!
Forget Pie Face, the only game worth playing in my house is, according to my kids, Don't Wake Dad. And right now it's down from £22.99 to £17.24 at Amazon.
It's suitable for little ones aged five years and older, and the premise is brilliantly simple. You have to be the first player to make your way round the board to the fridge for a slice of chocolate cake, without waking up the snoring Dad! Obstacles you have to avoid include a howling cat, a tinkling bell and a hooting owl.
My kids played this whilst at their babysitter's house recently and it's the only game they've even shown any interest in ever since. It's fair to say they're obsessed.
The game is suitable for 2-4 players and you'll need 2 x AA batteries which aren't included, so don't forget to pop them in your basket if you don't have a battery stash at home somewhere.
