Dr. Mario World[a] was a 2019 match-three mobile game developed and published by Nintendo in collaboration with Line Corporation and NHN Entertainment.

[3] Nintendo officially announced on July 28, 2021, that the Dr. Mario World service would end on November 1, 2021 at 2 AM North American Eastern Standard Time.

Additional doctors and assistants were acquired at random using either coins accumulated during gameplay or diamonds purchased with real-world currency.

In July 2021, Nintendo announced that they would be shutting down Dr. Mario World in November of the same year, with diamond packs no longer available for purchase from that date onwards.

[8] A website entitled Dr. Mario World Memories was then created to view player progress before the game was shut down.

[5] Destructoid also criticized the monetization model, writing, "It's a shame Nintendo cut and ran with microtransactions after one misstep, their first, no less, in the mobile market.

[17] Nintendo Life called the title "a game of two halves", heavily praising the multiplayer component while criticizing issues present in the single-player mode.
