Immerse yourself in the exciting adventures of Sonic, he will run away from the persecution of enemies, meet a pretty pink beauty, he will have a lot of other things to do in eight locations, and there will be no time at all to find green crystals. But you can help him collect them in Sonic Hidden Diamonds. There are ten of them hidden on each card. Search time is very limited, so do not waste it, but carefully look at the pictures, looking for barely borrowed emerald gems. As soon as you see, press and the crystal will become bright and shiny. You will no longer have to return to him in Sonic Hidden Diamonds.
