Math has never moved like this. Number Blast turns math practice into a fast-paced action game where every second counts. The problems stack up. The fire climbs. Your job? Blast the answer before the stack goes up in flames. This isn't another worksheet with a cartoon slapped on top. It's real math wrapped in real gameplay — the kind that makes students lean in, lose track of time, and actually ask to practice again. HOW IT PLAYS Solve to blast. Every correct answer clears a problem before the stack reaches the top. Miss too many and it's game over — so speed and accuracy both matter. Simple to pick up, tough to put down. A CHALLENGE FOR EVERY LEVEL From beginners just finding their footing to advanced players hungry to prove they're the fastest, Number Blast scales across ages and skill levels. Start where you're comfortable — then climb wave after wave as the challenge grows with you. MORE WAYS TO PLAY Number Blast is more than one game — it's a daily habit. Daily Number Cross — a fresh math puzzle every single day. Fill the grid, beat the challenge, and come back tomorrow for a new one. Blast Stacks, your way — switch between Starters and Advanced as your speed and confidence grow. Premium Video Lessons — unlock lessons that break down the math behind the game, so fast answers come from real understanding, not guessing. QuestUp Cards — a taste of the wider QuestUp world as you play. BUILT DIFFERENT Number Blast is the first math game created from the Black American Muslim community — built by a family who wanted their children represented in the tools they learn from. Representation isn't a feature we added. It's the reason we started. Every child deserves to see themselves as a creator, not just a consumer. Number Blast is where that begins. FOR PARENTS & EDUCATORS Sharpens mental math, speed, and focus Challenge levels that grow with your child Screen time that actually builds skills Safe, engaging, and made with intention A FAMILY MISSION All praise is due to G-d first. Number Blast started as a family project — parents and children building something together that we couldn't find anywhere else. Today it's part of QuestUp, a growing world of learning built to inspire the next generation, especially students of color, to fall in love with learning through play. This is just the beginning.
