Play Add It! Online – MS-DOS Game

Game Overview

"Add It!" is one of those charming little MS-DOS gems that sneakily turns a simple math challenge into a surprisingly addictive time-killer. Think of it as the brainy cousin of casual puzzle games—no flashy graphics or epic storylines, just pure, satisfying number-crunching fun. You’re thrown into a whirl of equations where speed and accuracy matter, making it the perfect blend of education and entertainment (though let’s be honest, you’ll mostly just crave beating your own high score).

For retro gaming fans, "Add It!" is a sweet slice of nostalgia—a reminder of when games didn’t need gigabytes of space to hook you. It’s straightforward, challenging in the best way, and oddly therapeutic, like a digital sudoku but with that old-school DOS vibe. If you miss the days when gaming was as simple as crunching numbers on a monochrome screen, this one’s a hidden treasure worth dusting off.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
