About this game

Puzzena is a collection of classic grid-based logic puzzles for players who enjoy deduction, problem solving, and brain teasers without guessing.

Explore more than 9,000 puzzles across Binary Puzzle, Tents & Trees, Shikaku, and Nonogram. Switch between different styles of logical thinking, choose the grid size and difficulty that suit you, or return each day for a new daily puzzle.

Every puzzle is pre-verified to have one unique solution and to be solvable using logic. Difficulty is based on the reasoning required to solve the puzzle, not simply on how large the grid is.

Puzzle types

• Binary Puzzle / Binairo

Fill the grid using two values while keeping every row and column balanced. Avoid forbidden sequences and make sure completed rows and columns remain unique.

Binary Puzzle is a clean deduction puzzle built around patterns, elimination, and logical relationships between cells. Start with smaller grids or move to more demanding challenges as your solving skills grow.

• Tents & Trees

Turn a quiet campsite into a logic challenge. Place exactly one tent next to each tree, satisfy the number clues for every row and column, and make sure tents never touch one another — even diagonally.

Tents & Trees combines spatial reasoning, counting clues, and deduction. Each placement affects several parts of the board, making it ideal for players who enjoy structured grid puzzles.

• Shikaku

Divide the entire board into rectangles. Every rectangle must contain exactly one numbered clue, and the area of that rectangle must equal the number inside it.

Shikaku is a rectangle division puzzle that rewards visual reasoning and careful elimination. Compare possible rectangle shapes, rule out overlaps, and partition the whole grid with no gaps.

• Nonogram

Use numerical clues along the rows and columns to reveal hidden pixel art.

Nonogram is a picture logic puzzle also known as Hanjie, picture cross, Japanese crossword, paint by numbers, pixel puzzle, or Griddlers. Work out which cells must be filled and which must stay empty until the hidden image is complete.

When a Nonogram is solved, the finished picture is revealed as the reward for your deduction.
