I think ‘start to play’ should also be accepted, and have reported this
I wrote that too but was marked wrong. Reported (Feb 2018).
I reported 'begin to play' should be accepted
I reported "start dancing" as an answer which should be accepted (March 2018)
It is accepted now - June 2018
Why can't you say start the game
Because "kucheza" is a verb (to play).
