About
Say it. Draw it. Win it.
Math Duel is the mental math racer where your voice is the controller. A problem pops up — 7 x 3 — and you just say "twenty one" out loud. Your racer jumps ahead instantly. No keyboards, no tiny buttons, no waiting. Prefer to stay quiet? Draw the answer with your finger and the game reads your handwriting on the spot.
Two ways to answer, one goal: cross the finish line before everybody else.
TALK TO IT
• Say the answer and move — the fastest input in any math game
• Understands full numbers, not just digits: "twenty four", "one hundred five"
• Works hands-free while you think out loud, exactly like real mental math
• Rather not talk? Draw the digits — smart recognition reads even messy handwriting
• Mic off? No problem. Every mode plays perfectly with drawing alone
RACE ANYONE, ANYWHERE
• ONLINE DUEL — up to 8 players. Jump in, the lobby fills, the countdown drops, go!
• LOCAL PLAY — up to 8 players on the same Wi-Fi. No accounts, no internet needed
• INVITE THE ROOM — friends without the app can join from their browser with a QR code no matter the OS phone!
• PRACTICE — race against bots with real personalities, from slow and steady to lightning fast
POWER-UPS, KART STYLE
Optional bonus problems float onto the track. Solve one and something explosive happens:
• Rocket — instantly solves the problem you're on
• Banana — the racer right behind you drops back
• Red shell — the racer right in front of you drops back
• Blue shell — the leader falls back three problems
• Hard rock — every opponent gets knocked back AND hit with a harder problem
Every hit shakes the screen, flashes red and sends that racer sliding backwards. Every rescue is one problem away.
BUILT FOR REAL BRAINS
• Three difficulty levels, from friendly single digits to fast multiplication and division
• Races of 10, 20 or 30 problems — a quick sprint or a real marathon
• Scores you honestly at the end: time, mistakes, the time you could have hit, and a rank from BAD to LEGEND
• Test Lab — a free, pressure-free space to practice speaking and drawing until it feels natural
