skj,
Try the game with a dictionary of your own language 
. It is more difficult to have success with a dictionary from another language. Even if you feel it hasn't worked it might be because you guessed the opposite page or top instead of bottom. Be easy on yourself and notice when that happens because it means it is working you just got it back to front. No matter anyway... it is a game only. It is by far more useful to you to enjoy photoreading the books that serve your needs.
One of the reasons the game doesn't always work is because the mind finds it boring so if you try to play it too often at once it stops making correct guesses.
On the whole you'll find it more interesting and perhaps fun photoreading a translation dictionary. One that translates english to your language and back again. No need to play the game just notice if the english words pop into you mind a little easier. Some people practice this for a few weeks and find that they understand the language easier.
If you have problems with other areas of photoreading it would be much better to work on them. Forget the game and make the system work.
