How 12 Volt Diamonds works
12 Volt Diamonds runs 5 reels with fixed paylines. Iron Dog Studio has not published an RTP figure for 12 Volt Diamonds, so we do not quote one — the game's own information screen inside the demo is the reliable source. Because the demo uses the same maths as the live game, it is a fair way to see how often the features actually land before deciding whether the game suits you.
