The game is powered with only one special feature and that is the free spins round. To activate the free spins in the Diamond Chief you need 3 diamond scatter symbols. I got 10 free spins initially but I retriggered the free spins and I won only 25 euros from the feature. Again I had the same amount of money on my balance as when I started playing the game. I continued spinning the reels because I knew that I will trigger the free spins soon. I just got the feeling and it turned out that I was right. This time I won around 15 euros. But my balance was still good. I was winning some small amounts but I was not losing a lot at once which is perfects, because we all know how these games act sometimes.
During the feature a new wild is added to the reels. The shield symbol is the new wild and every time it is a part of a winning combination it awards you with a multiplier of x 2 or x 3. I did not see the power of this symbol though. It seemed like it was never in the right place. Anyhow the Diamond Chief is an awesome video slot game and if you have the chance you should play it.
