+# Tic Tac Toe Lab Assessment
+
+## Checkpoint 1
+Looks good.
+
+## Checkpoint 2
+Nice! The ranges make use of the fact that there are some useful patterns 
+in the indices of row- and colum-based wins.
+
+## Checkpoint 3
+Almost--but this isn't a propabilistic process. Having the initial state's
+current and future reward be zero means that if everyone plays perfectly, 
+the game will always be a draw.
