I'm working on a slot machine of 3x5. But I like to extend it with colored images in each cell, and a boarder in each cell. They can also form winning combo's. I also want to add multiple bonus games. I also like to hold certain cells before spinning again. What do you think of such a game concept? Update: Why 50 reviews and no responses? I use GM since version 5.3. I have some nice experience and I made several games.
