``` My code isn't quite the same as Kenneth's code in which I have a twenty by 5 board but it should still allow you to move sideways on a smaller board.

```def move_player(player, move):
x,y = player
if move == "A":
x -= 1

if move == "D":
x += 1

if move == "W":
y -= 1

if move == "S":
y += 1

if move == "WA":
x -= 1
y -= 1

if move == "WD":
x += 1
y -= 1

if move == "SA":
y += 1
x -= 1

if move == "SD":
y += 1
x += 1

return x, y

def get_moves(player):

moves = ["A", "D", "W", "S", "WD", "WA", "SD", "SA"]

x,y = player
if x == 0:
moves.remove("A")
moves.remove("WA")
moves.remove("SA")

if x == 5:
moves.remove("D")
moves.remove("WD")
moves.remove("SD")

if y == 0:
moves.remove("W")
moves.remove("WD")
moves.remove("WA")

if y == 18:

Hope this helps and happy coding Jason Smith. :)
