Mix the elements together by dragging them so they touch to create new elements. You can keep creating new elements. You don’t have to mix in the mixing area but it helps to organize the board. You can also use the mixing area to mix elements from page one with elements from page two and three. Hint: There are 4 hidden elements which requires you to mix 3 items together.
There are currently 72 elements but I might add more. Credits to karkade35 for the thumbnail and a few sprites.
