Arcade action and math learning for all ages! Ad-free and fully customizable!

Number Delver is a fast-paced arcade game for all ages that challenges math skills and knowledge. Help the Delver collect the correct answers on each level to escape the planet! Dodge the Ignorunts that will try to catch you, or transform into Super Delver to defeat them! Use power-ups to master the board and control the chaos!


- Zany graphics and sound and a groovy original soundtrack keep players engaged as they train memory and knowledge!
- Five different enemies will chase, distract, and even try to trick you!
- Slapstick power-ups help you evade the Ignorunts and maximize your score!
- Compete for high scores and record your progress in the Hall of Fame!
- Completely customizable gameplay including types of math content, math difficulty, and game challenge! Adjust to practice toward individual learning goals.
- No ads! Zero! Zilch! Play offline with no annoying or inappropriate commercial distractions.


Each level contains a grid of numbers or mathematical expressions (like 3+7 or 10÷2). Swipe anywhere on the screen to move the Delver around the board. When the Delver hovers above a cell that matches the target, tap anywhere to collect it.

Avoid the Ignorunts! Shields will sometimes appear in particular cells — Delver is safe there.

Collect items and power-ups by moving into the cells in which they appear.

When the Delver's power meter is fully charged, tap the button to transform into Super Delver and defeat the Ignorunts!


Number Delver is free to download, contains no ads, and has no online features, making it appropriate for home and school play. The “multiples” game type is free to play. A single in-app purchase unlocks all game content types (factors, primes, equality, and inequality) and settings options, allowing parents or teachers to customize the learning experience for different learner levels.
