Spelldoku

Every grid hides a magic word. Can you find it before the last letter falls?

Spelldoku is two puzzles in one. Pick one letter in every row, every column and every colour, never touching. Each letter you find flies into a crystal orb, jumbled up. Then read the riddle and work out the word.

Know the answer early? Cast the spell while letters are still hidden and earn a rare rune. Prefer pure logic? Finish the grid yourself to earn its sigil. Both paths climb the same magical tree.
