Spectrum Solitaire is completely new, unique and addictive game invented by Sergiy Osadchiy.

In this solitaire you play with 49 special cards that are made of 7 different backs and 7 diamonds on rainbow colors: red, orange, yellow, green, blue, indigo and violet. Your goal is to move all cards from game field to foundations with set of simple rules:
* You can move the cards between columns provided that either card background or diamond color matches color of background or diamond of topmost card in target column.
* Every foundation pile can contain only cards of same background color, with diamond colors from red to violet.
* With easy difficulty mode there is eighth column that accepts any card as first one and other cards according to common rules. On medium difficulty that column becomes a cell and can hold only one card. In hard mode there is no extra column at all.
* The game is won when all cards are placed on foundation piles.

Give you color perception a test, try to win! And don't forget Roy G. Biv!
