Spectrum Slot Review

The Spectrum game can be found at casinos offering Wazdan software. Wazdan is one of the better established software developers in the online gaming market having been in operation since 2010. Unlike many of the smaller casino software providers Wazdan offer a selection of casino table games featuring some of the major table games, with a strong focus on slots games. Wazdan do publish the RTP/House Edge information for their slots games within their games. As such we can say that the House Edge for Spectrum is 3.7%.

Spectrum is a 5 reel game that is 3 symbols high. The game uses 10 traditional paylines, playing from left to right.

Special Symbols

Wild – The “Gold Pyramid” is the game’s Wild symbol, substituting for all symbols. When a Wild symbol is revealed it will expand to fill the reel. When this happens, you will be awarded a re-spin as the stacked wild remains in place. If you reveal another wild symbol during the re-spin the process will repeat, something you can achieve 3 times in total. Wilds can only appear on reels 2,3 and 4 and all re-spins are played at the same level as the original bet.


Spectrum is a basic game with a futuristic design that suggests excitement but does not deliver it. The game looks good, with an intricate background and bright, colourful symbols to keep your attention as you spin. The only features I can mention here are the wilds that gain you re-spins and turn fully stacked in place as they do so. There are no free spins and no bonus features, which is disappointing for a game that looks as if it promises much more. The house edge is reasonable, making this game good value for money and allowing us to award an average score instead of a poor one.
