With Nintendo you never know when games are going to appear on Nintendo Switch Online, case in point, they have announced that the two Legend of Zelda games from GameBoy are now available to play on the service. That means with the addition of Oracle of Ages and Oracle of Seasons, the count of Zelda games on Switch is now 13, 16 if you include spin-offs.

The big thing with these games is that you could share information between them via password, a system that has been retained in these versions. Here is a little on each of the games.

In The Legend of Zelda: Oracle of Ages, the Land of Labrynna has fallen into darkness. But hope remains that a hero can still prevent Veran, Sorceress of Shadows, from plunging the world into an endless night. Link is ready with a hand to lend help and the power to bend time, but his abilities also present unique challenges. If a river blocks Link’s path in the present, he can travel to the past and move a stone, redirecting the flow of water. Likewise, if he plants seeds in the past, he’ll find full-grown trees and vines waiting for him when he returns to the present. With a cast full of vivid characters, including Impa and the giant Maku Tree, and a range of iconic tools to deploy, Link must crisscross through the past in order to safeguard the future.

In The Legend of Zelda: Oracle of Seasons, Link must fight to stop the power-hungry general Onox in the troubled land of Holodrum, where the harmonious cycle of nature has been disrupted. Don’t let the land slowly wither – instead, change the seasons to overcome puzzling obstacles! If Link finds a small plant at the bottom of a cliff, transform the season to spring, and use the newly grown flower to get a boost up to the top. Or when facing a deep lake, use the Rod of Seasons to shift into winter, letting Link walk over the ice. Can Link rescue the Season Spirits before all is thrown into chaos and the bountiful gifts of nature rot?
