Nonova: Nonogram Picross

New puzzles every day with a guaranteed single solution — no guessing, just calm logic and a hidden pixel-art picture waiting at the end.

Fill the right squares by following the numbers on every row and column, and watch a hidden pixel-art picture slowly appear. Nonova is pure logic — no timer rushing you and no luck involved. Every endless puzzle is generated on the spot and verified to have one single solution you can always reach by reasoning, so you never have to guess.

If you grew up solving nonograms, picross, griddlers or Japanese crosswords on paper, this is the same calm, satisfying deduction on your phone: clean, quiet and made for players who want to think, not tap frantically.

HOW IT WORKS

• The numbers beside each row and column tell you the lengths of the consecutive filled blocks.
• Fill the squares that must be shaded and mark the empty ones with an X to keep track of your progress.
• Drag to paint a whole line at once — the axis locks like classic picross, so a single stroke stays perfectly straight and errors are easy to avoid.

WHAT YOU GET

• Endless puzzles in four sizes: 5x5 to learn the ropes, 10x10 and 15x15 for a proper session, and 20x20 for experts, with smooth pinch-zoom and pan on the bigger boards.
• A guaranteed unique solution on every single board, provable by logic alone — our generator checks each grid with a line solver before you ever see it, so there is never a lucky guess.
• Assisted mode that flags a wrong fill as a mistake and dims the clues you have already finished, so you always know exactly where you stand.
• Expert mode with no live checking and a manual Check button for the real pen-and-paper feeling — and it pays out double the coins.
• A Daily Puzzle with a streak counter and a full month calendar, so there is always one fresh challenge to come back to every day.
• Themed pixel-art packs — animals, food, Spain and space — where each finished grid reveals a colourful picture you can save and share with friends.
• Smart hints when you get stuck, coins to spend on them or unlock new packs, and detailed statistics with your best times for every size.
