Each level has a similar objective with a unique challenge. You're given a target number, and your goal is to add individual numbers together to meet that target. You do this as many times as possible before the time is up. Each time you reach the target, you move closer to earning coins and completing the level. When all three coins for the level have been acquired, you unlock the next level.
My role involved leading the user experience, visual design, animation, and branding of the mobile game. The work was done in partnership with Numbers & Logic.
