The highest paying symbol in the game is the yellow germ.

  • Medi Scatter. The scatter symbol in the game is a capsule. The capsule scatter lands anywhere on the reels during the base game. Landing 3 capsule scatter symbols in a single spin triggers the Medi Bonus Round.

During the Medi Bonus Round, all wins are paid as multiples of the bet line. When there are no new winning combinations formed, the feature ends.
