> Try adding two X's in a row. It will not work. It's waiting for an O, and once that is triggered it waits for an X and so on.

If you try to make a move out of turn it seems like the illegal move is still "queued up" somehow. So as soon as you make a legal move the previously attempted illegal one occurs, as it's now legal.

In fact, this resulted in an interesting game where both sides won:

    { type: "X", payload: 0 }
    { type: "O", payload: 8 }
    { type: "X", payload: 1 }
    { type: "O", payload: 2 }
    { type: "X", payload: 3 }
    { type: "O", payload: 6 }
    { type: "X", payload: 7 }
    { type: "O", payload: 5 }
    { type: "X", payload: 4 }
    { type: "XWins" }
    { type: "OWins" }
