how to create a brick game, a grid 6x7

hi.

I´ve been looking on the different tutorials on grids but I´m still clueless on how to make a brick game.

I'm trying to create a brick game where I put bricks on a 6x7 grid. there are 19 types of bricks that are being randomly on the grid (it can only be two of the same type next to each other).
