'Game over' is correct. we can't use 'Game enough'.

first think some sentences in hindi then try to translate those in english. everyday, one hour you should speak English and also write an essay on any topic regularly.

there means vahan , udhar etc. their means uska, unka etc. now, you should try to make sentences.

I am neha.

You should practice the conversation game everyday.

you should try to speak in English at least 10 minutes with your friends.
