Nintendo has expanded the Switch Online Game Boy library today with three more classic titles today.

The latest batch of titles includes the platformer Super Mario Land, the Breakout-like release Alleyway, and the sports game Baseball. All of these were released in 1989 and line up with the Game Boy's 35th anniversary celebrations:

"To properly celebrate 35 years of the Game Boy™ system, we have to take it back to year one! Game Boy launched in 1989, and with it arrived classic titles such as Baseball, Alleyway™ and the first Super Mario game available on the system, Super Mario Land™. Today, Nintendo Switch Online members can play all three of these original launch titles as the latest additions to the Game Boy – Nintendo Switch Online library. All just in time for the system’s 35th anniversary!"

Japan has also received one extra release! It's the action-adventure Kaeru no Tame ni Kane wa Naru (The Frog For Whom the Bell Tolls), which was originally released by Nintendo in 1992 and has some connections with The Legend of Zelda: Link's Awakening.

This same game was originally revealed for Nintendo's Switch Online Game Boy library in February last year and is exclusive to Japan's service, so you'll need to have access to a Japanese Switch account to try it out.
