🐾 Find the Right Spot

Look at the colorful board and work out where each target belongs.

The grid is divided into regions of different shapes and colors. There is only one correct arrangement, and every choice affects what you can do next.

To complete the puzzle:

• Find one correct spot inside every region
• Make sure no two targets share the same row
• Keep every column to one target
• Leave space between targets, including diagonally

Start with what you know, rule out what can't work, and let each discovery lead you closer to the answer.

No guessing needed — the clues are already on the board.

🎨 Turn Numbers into Pixel Art

Switch things up with classic Nonogram puzzles.

Numbers around the grid tell you which cells belong to the hidden picture. Read the clues, fill the right squares, mark the empty ones, and slowly watch the artwork appear.

• Solve grids with row and column clues
• Reveal colorful pixel pictures
• Discover new images as you progress
• Explore different puzzle sizes
• Take on easier or more challenging grids
• Get a hint when you need an extra clue

Each finished puzzle transforms a grid of numbers into a picture worth revealing.
