SmartPhone is a fun sliding puzzle in the form of a fold phone, with 32 challenges to take with you wherever you go. Choose a challenge and place it on top of the other challenge cards, inside the flip-up top of the mobile phone, so your chosen challenge is visible. Each challenge features a person’s name. The challenges are arranged alphabetically from easy to difficult. Move the buttons on the keypad so that all the numbers in your challenge are visible through the buttons with a cutout hole. The only numbers that count are the ones visible through the cutouts. Numbers that are completely covered or uncovered do not count as part of your solution.
