Super Mario Land does not feature any secret endings or alternative conclusions based on specific actions or collectibles. The game has a single, definitive ending: Mario rescues Princess Daisy from Tatanga. Regardless of your score, the number of lives you have, or whether you found every hidden coin, the final cutscene and credits will always be the same.

This is typical for early Game Boy titles, which often prioritized straightforward gameplay and replayability through score attacks rather than branching narratives or multiple endings. The satisfaction comes from completing the journey and mastering the challenges, not from unlocking a different story outcome.
What to expect from the ending:
- Tatanga's defeat: After defeating Tatanga, his spaceship explodes.
- Princess Daisy rescued: Princess Daisy is freed from her captivity.
- Mario and Daisy reunion: Mario and Daisy are reunited, and she gives him a kiss.
- Credits: A short credit sequence will play, often featuring sprites of the game's enemies and characters.
While there's no secret ending, the journey itself is the reward. Enjoy the classic charm and unique elements of Super Mario Land as you work towards the satisfying conclusion of rescuing the princess.
