A South African entrepreneur has developed a variant of roulette that features 49 numbers instead of the usual 37.

Fidos Kleovoulou calls the game Roulette 49 and says that by adding 12 numbers the average house hold moves from 2.7 per cent to 3.69 per cent.

He is now seeking manufacturers who may be interested in taking the project further.

Roulette 49 has been patented in South Africa.
