The Cosmic Crystals slot game can be found at casinos offering Iron Dog software. Iron Dog are one of the smaller software providers currently on the market, but the appear to be a subsidiary of the far larger and better established 1x2Gaming. They do not offer a full casino platform, but primarily seem to be used as a bolt on package for extra slots games. Iron Dog do publish the Return to Player (RTP)/House Edge information for their slots games within the game paytable. As such we know that the house edge for Cosmic Crystals is 4.99%.
Cosmic Crystals consists of 5 reels, 3 symbols high, with 50 different paylines, playing from left to right.
Yellow Crystal – The “Yellow Crystal” symbol is the most valuable in the game, offering the most lucrative prizes. Two “Yellow Crystal” symbols, as part of a winning combination will earn you 5 coins, three will be 25 coins, four will be 150 and five “Yellow Crystal” symbols will earn you 1000 coins.
Wild – The “Orange Crystal” is Wild, substituting for all symbols.
Free Spins – You gain a free spin on any spin that has not landed a winning combination. There is no limit on the number of free spins and, as such, they will continue until you land a winning combination.
Wild Reel – Wild symbols can only appear on lines 2,3 and 4. Landing 1 or more wild symbols on the reels 2,3 or will trigger the “Wild Reel” feature. When this happens the wild symbol will expand to fill the reel and will stick in place if it is not part of a winning spin during the game’s Free Spin sequence.
This initial offering from Iron Dog doesn’t have a huge amount to offer. The theme is basic, ensuring that there can be no narrative built into the game. There is no bonus feature or scatter symbol, meaning that we’re relying on free spins and wilds to keep us entertained. However, we do like expanding wilds and the re-spin till you win is a nice touch. The house edge is pretty high, sitting at nearly 5%, making it one of Iron Dog’s least profitable games.
