Game Overview

Remember that old-school NES charm? Sesame Street123 brings it with two surprisingly fun math games for little ones. First up, Astro-Grover—you help Grover wrangle these bouncing alien Zips by counting them, adding or subtracting as they zoom around. It’s chaotic in the best way, like herding hyperactive space puppies.

Then there’s Ernie’s Magic Shapes, where you match colors and shapes to solve his little puzzles. The shapes float around like they’ve had too much cookie monster milk, which makes it weirdly satisfying when you finally line them up right. Definitely one of those "wait, was I just learning?" games where the kids won’t even realize they’re practicing math.

Perfect for ages 3-6, especially if they’re into that classic Sesame Street vibe with chunky pixels and cheerful music.
