Added for the daily speedrun challenge. 5 7x7 puzzles in 2 minutes. I enjoyed doing those for a long time. Game itself is okay.
Picross 3D
Murder by Numbers
Visual novel hybrid. Only recommended if you like the story. There's no pure puzzle mode.
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.
Picross 3D: Round 2
Picross e
Series. Very polished for a quick puzzling experience.
Voxelgram
Steam recommendation. There's over a thousand puzzles on the workshop, and the ingame interface makes downloading and playing them easy.
