The object of Alchemy is to transform the entire board into gold by placing magic RUNES on every square. When you turn a whole board to gold, you will proceed to the next, where you earn more points but the game becomes more difficult. RUNES are magical symbols that come in different shapes and colors. You place these on the board to change the square underneath to gold. Runes must be placed next to an existing Rune, and they must match all adjacent Runes in either their shape, their color, or both. STONES are grey blocks that act as "wild cards." Any type of Rune can be placed next to a Stone. SKULLS are magical "bombs." You can place them on any existing Rune to destroy it. The FORGE is the round metal object on the left sidebar. It fills with molten lava whenever you discard a Rune, and cools down when you place a Rune successfully. When you fill the Forge completely, the game will end.
