Making a grid of canvas's where there are lots of mini versions of this game.

Can someone help guide me into creating a grid of canvas's, each running a separate game. Im currently trying to repeat the steps and add the same neural network used in flappy birds example, to one of my projects. The only issue is, in my game I want two player objects to learn to fight against each other, which would require me to making a grid of canvas's, each simulating their own game.

any help would be appreciated!
