California Gold it is Microgaming game, but with this sort of games, which actually unlikely made by Microgaming. I am also never saw any game like this in download casinos, so it is just in Quickfire package (i.e. you will find it at many casinos with Quickfire software).
There is 25 paylines on this slot game, and game looks typically to similar games in this sort. They old of course, but look still good, I am even think that games look better than Microgaming nine liners. Of course far away from modern games, does not expect anything even close to this. But ok, game looks ok for me, really.
Game has all chances to be played by you not only once, but again and again, it is dynamic one and I found it interesting for myself. Why no, there are wilds which double win (only on reels 2, 3, 4). If you get 3 wilds at same spin - you got bonus feature. Nothing really special, just picking mine and see short animations. Can't say about max prize there, I have had couple of 50x total bet bonus games here, and also not forget that 3 wilds at same time also usually give moderate win, but can give huge one. Another feature - freespins feature, which triggered by 3 or more scatters, it is triggered not very hard, not like at DOA this is for sure. 10 freespins with x 3 multiplier, nothing special, but wins there is good.
I played this game probably 10 times in total, not much, but each time I have decent playtime, frequest features, and some moderate wins. I never hit more than 100x total bet, but there is was some frequent good wins, which boost balance good.
Can't say anything interesting more, game is interesting to play sometimes, you know this all modern game is awesome of course, but sometimes it is great to give a shot to old game, such games usually give a lot of playtime, and sometimes they also pay decent money.
Generally speaking, I am have nothing too bad to say about this game.
