Rune Sudoku

Rune Sudoku was a minigame where a player completes a sudoku puzzle in return for rewards. However, it was different from normal sudoku in the fact that in Soulsplit, there are runes rather then numbers. It has been known for its potential skilling related rewards, such as Farming seeds and Herblore secondaries.
