There’s Gold Yonder
Well, maybe not gold, but you could win credits if you can line up enough matching symbols to make it happen. Nucleus Gaming has come up with a gold-themed slot that brings a chance to win up to 2,330,000 credits. But even if you don't win that many, you stand a chance of enjoying exploding symbols whenever you get a winning combination.
When you get a successful combination of gems on the reels, they'll explode, causing others above to drop down and more new ones to appear. The multiplier meter also increases, so the more wins you get in a row, the larger they will be.
There's Gold Yonder also has TNT barrels that will bring you free spins when you get three on the first three reels of the game. The multipliers get bigger still for successive wins in this feature, so you could rack up some decent prizes very quickly indeed. You may not find gold in this slot, but the game does bring a chance to win lots of decent credit prizes.
