Although it is a tradition in Christianity to give up something for Lent, such as sweets, it has never been suggested by the Reverend from the pulpit that the game of games should not be played. Indeed the non-stipendiary minister in the parish of Six Mile Bottom was known to be an afficionado, so legend had it.
I digress though, and to begin the game, in honour of it being the feast of the annunciation, begin with a station near to St Mary's, Edgware Road (Bakerloo).
