The Heart in Super Mario Land functions as a 1-Up, granting Mario an extra life immediately upon collection. These are among the most valuable items in the game, as they directly contribute to your ability to continue playing after losing lives. Hearts are generally rarer than Super Mushrooms or Superball Flowers and are often found in hidden or less obvious locations.

Location & Usage:
- Hidden blocks: Most commonly found in invisible blocks that must be hit from below to reveal.
- Bonus stages: One of the two ropes in the bonus stage after each level will always yield a Heart.
- Immediate effect: Grants an extra life as soon as it's collected.
Always prioritize collecting Hearts when you see them. Accumulating a good stock of lives is essential for tackling the later, more challenging worlds and for facing the final boss, Tatanga. Make it a habit to jump in suspicious areas to uncover hidden blocks, as this is your most reliable source of Hearts outside of the bonus stages.
