Puzzena: Nonogram & Tents

Eleven classic grid logic puzzles in one app: 32,000+ boards, up to 3,000 per type, each type as deep as an app that ships nothing else.

Every board is verified before release: exactly one solution, solvable by pure deduction. You never have to guess. Choose a type, a grid size and a difficulty, or open today's daily puzzle and keep your streak going.

WHY THESE PUZZLES ARE DIFFERENT

• Exactly one solution, proven by a solver before the puzzle ever reaches your phone.
• Solvable by logic alone. No puzzle needs a guess or a lucky branch.

ELEVEN PUZZLE TYPES

• Nonogram
Use the number clues along the rows and columns to work out which cells are filled and which stay empty, until a hidden picture appears. Also known as hanjie, griddlers, picture cross, paint by numbers, japanese crossword or pixel puzzle. 2,330 pictures to uncover, each joining your gallery.

• Tents & Trees
Place exactly one tent next to each tree in the campsite. Match the tent counts for every row and column, and never let two tents touch, not even diagonally.

• Shikaku
Divide the whole board into rectangles. Each rectangle holds exactly one number, and its area equals that number. A rectangles puzzle, also known as divide by box, that rewards patient elimination.

• Hitori
Every cell starts with a number. Shade cells until no number repeats among the open cells of any row or column. Two shaded cells may never sit side by side, and every open cell must stay connected in one area. A japanese number puzzle solved entirely by elimination.

• Light Up
Place lamps until every floor cell is lit. A lamp lights its own cell and its line of sight until a wall blocks the beam. No two lamps may light each other, and a numbered wall must touch exactly that many lamps.

• Bridges
Link the islands with straight bridges. Each island takes as many bridges as its number, bridges never cross, and every island ends up connected. Also known as hashi or hashiwokakero.

• Binary Puzzle
Fill the grid with two values, keep every row and column balanced, avoid three of a kind in a row, and keep all completed rows and columns unique. Also known as binairo.

• Dominoes
Cover the number grid with dominoes, using every domino of the set exactly once. Also known as dominosa or domino puzzle.

• Islands & Walls
Each number is an island of that many cells; the rest is one connected wall with no 2x2 block. Also known as nurikabe.

• Cross Sums
Fill the white cells with digits 1 to 9 so every run adds up to the number in front of it, and never repeat a digit inside one run. Also known as kakuro.

• Loop the Loop
Join the dots into one closed loop that never crosses itself. Each number says how many of that cell's four sides the loop uses. Also known as slitherlink or fences.
