Einstein himself used variants of this quote at other times. For example, in a 1943 conversation with William Hermanns recorded in Hermanns' book Einstein and the Poet, Einstein said: "As I have said so many times, God doesn't play dice with the world."

Context: Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of the "old one." I, at any rate, am convinced that He does not throw dice.
Die Quantenmechanik ist sehr achtung-gebietend. Aber eine innere Stimme sagt mir, daß das doch nicht der wahre Jakob ist. Die Theorie liefert viel, aber dem Geheimnis des Alten bringt sie uns kaum näher. Jedenfalls bin ich überzeugt, daß der nicht würfelt.

“Not only does God play dice but… he sometimes throws them where they cannot be seen.”
During the same 1994 exchange with Penrose as the previous quote, transcribed in The Nature of Space and Time (1996) by Stephen Hawking and Roger Penrose, p. 26 http://books.google.com/books?id=LstaQTXP65cC&lpg=PA26&dq=hawking%20%22where%20they%20can't%20be%20seen%22&pg=PA26#v=onepage&q=&f=false and also in "The Nature of Space and Time" (online text) http://arxiv.org/abs/hep-th/9409195
Unsourced variants: Not only does God play dice with the Universe; he sometimes casts them where they can't be seen.
Not only does God play dice, but... he sometimes throws them where they cannot be seen.
Variant: So Einstein was wrong when he said "God does not play dice". Consideration of black holes suggests, not only that God does play dice, but that He sometimes confuses us by throwing them where they can't be seen.
“Not only does God play dice with the world—He does not let us see what He has rolled.”
