simple 3x3 guessing game

[l0311]

hi, i'm trying to make a guessing game that is on a 3x3 grid.

the grid has numbers 1-9 placed randomly on it, but the user can't see this as they are covered by question marks '?'

The aim is for the user guess the correct numbers.
if the user guesses correctly the '?' is unmasked and it displays the correct number
if the user guesses incorrectly they have another attempt to guess

the game should display like this:

???
???
???

Please enter the row to check (1-3):


please can you tell me how to go about making the game.
thanks
