Nintendo announced Nintendo Switch Online has added more classic games from the Game Boy era this week.

Nintendo Switch Online has added Donkey Kong (also known as Donkey Kong ’94) and Mario’s Picross, released for the original Game Boy back in 1994 and in 1995, respectively.

Here’s a rundown on both games, plus a trailer:

Mario’s Picross

Use logic to reveal mysterious hidden pictures! Help Mario unlock the mystery of Picross. The secrets lie in the numeric codes at the top and on the left side of each window. Decipher these numbers and uncover a hidden picture in every mind-bending puzzle. It will take quick wits and a speedy pace to solve the clues before the clock runs out. Chisel away boxes strategically and reveal the hidden image in record time. But be careful—every mistake will cost you precious minutes! There are more than 250 brain-bending puzzles to solve in all, with different levels of difficulty to provide mind-melting puzzle action for players of any skill level.
