Crossdots

This popular logic puzzle is known by many names, including Nonogram, Paint by Number, Griddler, Picross, Pic-a-Pix, Hanjie and many others. To add to the glorious chaos we've chosen our own name: Crossdots.

FEATURES

* Interact directly and intuitively: tap a cell to color it, tap again to cross it out, again to clear. No fussing with crosshairs or switching between pen and eraser.
* Stop tapping a cell and after a few seconds it will lock to prevent you from accidentally changing it with stray taps. Double tap to unlock.
* Long press then drag to change multiple cells.
* Pinch to zoom and resize the puzzle to fit your device screen.
* Undo back to any point in your puzzle history. (Undo replaces the Snapshots feature in prior versions.)
* After you've solved a puzzle, watch an instant replay.
* Highlight a row or column to help you focus on what you are solving.
* Puzzles are single color; you have the option to switch colors as a tool to help you find the solution.
* Automatic saving of puzzles: come back to the app and pick up right where you left off.
* Puzzles are organized into books. Each book offers the first few puzzles free to try. Buy the book to unlock the rest.

Good luck and have fun!
