No quicker is Christmas over than the Easter slog begins, and advertising agency supreme Saatchi & Saatchi has come up with a game for UK bus shelters that will promote Cadbury's Creme Eggs.

The interactive touchscreen game will see travellers attempting to smash as many falling digital eggs as possible in 20 seconds and release their goo.

The new interactive adverts are set to appear in bus shelters across London, Birmingham, Glasgow, Manchester, Nottingham, Sheffield and York.

Have a look at the video above for what to expect, and keep your eyes peeled if you're visiting any of the above cities for a chance to have a go.
