The object of this mysterious game is to turn the game board from lead to gold by placing magic symbols - "runes" in board's squares. Each rune must be placed to another by shape or color (or both) concordance. If you complete a row or a column of runes they disappear clearing your gaming place and scoring points. If there is no vacant place for your rune you can simply discard it. If there are a lot of runes on the board each new rune must fit neighboring runes by color or shape. There are also such units as "grey stone" (you can place it anywhere) and a "scull" (it will destroy any unit it is placed on).
