Latin name for German game (5)

I believe the answer is:

lotto

I'm a little stuck... Click here to teach me more about this clue!

'german game' is the definition.
'lotto' can be an answer for 'game' (the UK National Lottery). I am unsure of the 'german' bit.

'latin name' is the wordplay.
'latin' becomes 'l'.
'name' becomes 'otto' (Otto is an example).
'l'+'otto'='LOTTO'

'for' is the link.

Can you help me to learn more?

(Other definitions for lotto that I've seen before include "Venetian painter - gambling game" , "house" , "Game of chance involving balls" , "Game of chance similar to bingo" , "form of gambling" .)

I've seen this clue in The Times and The Sunday Times.
