Mashup children’s games, such as:

Lego battleships - must be easy, using one of those big bits of board they sold to look like the moon and some of the smaller bricks, no? And is a person who dreams up amazing things to do with Lego a Leguru?

Chris thought of a sort of vet approach to Operation, where you had to perform tricky surgery on an ailing mule, and if your tweezers touched the side, it bucked wildly. Possible name: Buckeration. Or Operoo.

My favourite is Guess Whodo: Cluedo (AKA Clue in ‘merka) meets Guess Who (AKA Whodat?! in ‘merka).

Here’s how it works: Each player has three rows of items flipped up, facing towards them. Each line is different - one line of people, one of places, one of weapons. Each card is illustrated in some detail. Each player picks one from each line to create a plot: person, place, weapon. The players take it in turns to interrogate each other to deduce the details of their murder. A game might go like this:

A: OK, does the murderer have blue eyes?
B: No
A: [flips down Miss Scarlett and Professor Plum]

B: Did the location have a wooden floor?
A: Yes
B: [Flips down cards until only the Ballroom and Kitchen remain]

A: Was the weapon made of metal?
B: No
A: [Flips down dagger, lead piping]

B: Was the murderer wearing a hat?
A: Yes
B: [Flips down everyone except Mrs White and Colonel Mustard]

A: Did the location have a view of the lake from the windows?
B: Yes
A: [flips down kitchen, study, billiard room]
…and so on.

Surely this is a marketing mashup waiting to happen? You saw it here first.
