Piczle Cross Adventure
Meow Tower: Nonogram
Paint it Back
Khimera: Puzzle Island
Pixel Puzzle Collection
Voxelgram
Steam recommendation. There's over a thousand puzzles on the workshop, and the ingame interface makes downloading and playing them easy.
Picross e
Series. Very polished for a quick puzzling experience.
Picross 3D: Round 2
Picross S
Series. Mega puzzles use the same puzzles as normal, just with different clues. Take a long break before doing those so you won't remember the answers.
Murder by Numbers
Visual novel hybrid. Only recommended if you like the story. There's no pure puzzle mode.
Picross 3D
Pokémon Picross
Added for the daily speedrun challenge. 5 7x7 puzzles in 2 minutes. I enjoyed doing those for a long time. Game itself is okay.
