***This is the iPhone/iPod Touch version. If you are using an iPad, for best results please use the iPad version.*** Welcome to Paint By Numbers! I made the game I wanted to play and I hope you enjoy it as well. Learn to become a master painter by finding all occurrences of the number or pictogram to the left of the screen. As you find them in the grid, they are painted to match the color to the left of the screen. After you find all matches, the next number or pictogram appears. Rinse and repeat until the entire painting is finished. For those of you who don't like reading help screens: You move around the puzzle by swiping the screen with one finger. This free version includes one puzzle, which should take a couple hours to solve! The full version currently has 40 puzzles. - "High Detail - Great Concept" - "...this is an awesome idea!"Have fun and play responsibly! Feedback is very appreciated. Please contact me at firstname.lastname@example.org if you have questions or feedback.
