A new picture every day, hidden in the numbers.
A Japanese logic puzzle — nonogram, picross or griddler — where the picture only appears if you reason it out.
Korogram is a nonogram (picross, griddler) designed for two minutes a day. The numbers in each row and column tell you how many consecutive squares to paint; you figure out where. When you finish, the grid melts away to reveal what you've drawn.
NO GUESSING ALLOWED
Every nonogram has a single solution reached purely by logic. No trial and error here: our generator guarantees it, which is why mistakes cost you.
THREE LIVES, OUT IN THE OPEN
Each square is checked the moment you tap it. If you miss, the square reveals its true state, stays marked, and can't cost you another life. If you run out of lives you can keep going — but your trophy remembers: gold for a flawless run, silver with mistakes, bronze if you had to continue.
THREE WAYS TO PLAY
Daily challenge: the same board for everyone, 10×10 on weekdays and 15×15 on weekends.
Monthly challenge: a 20×20 open all month, to chip away at.
Practice: four sizes, 5×5, 10×10, 15×15, and 20×20, with no limits.
And the archive: every past day is still there, ready to be played or to upgrade your trophy.
WHAT YOU TAKE AWAY
Every finished picture goes into your collection with its name, a fun fact worth knowing, and a link to read more. You always walk away learning something new.
CHALLENGE ANYONE
Send the board you just solved to a friend. Whoever makes fewer mistakes wins; time is only a tiebreaker.
MADE TO BE PLAYED
One finger paints and drags, two fingers zoom. Haptics respond to every square, and putting your phone on silent mutes the sound, not the feedback. On tablets, the whole board fits perfectly.
No internet required, no mandatory accounts, and no rush.
