No Time For Math is a fast, brutal reflex challenge where every second matters. Solve arithmetic on the fly, keep your streak alive, and climb the score tiers to go from “I wanna be a Genius” to a bonafide Genius human-calculator at mental math. Modes • Time Attack: Start with 20 seconds. Every correct answer adds time. Every wrong answer subtracts time. Bank your momentum and go for a record. • Lives: You get 3 hearts. Each problem is timed; answer before the clock wipes you. • Practice: Endless grind with per-problem pressure. No run-ending timer, no running out of lives but no score tracking; just you vs. the next problem. Two ways to play • Multiple Choice: Six answers. Instant decisions. Pure speed. • Numpad Mode (“HARDER”): Type the answer. Higher risk, higher reward, bigger score multiplier. What’s inside • Your most familiar & friendly arithmetic operations: +, −, ×, ÷ • Six Levels of Difficulty: Hard, Brutal, Nightmare (Standard and HARDER versions) • Streak scoring: Keep chaining correct answers to ramp points fast • Score multipliers: Difficulty + input mode stack for maximum reward • Detailed results: Accuracy, best streak, and a full problem-by-problem history • Local high score tracking • Sound toggle if you don’t want to feel like you’re battling evil by solving math. If you want a game that forces you to build up your arithmetic skills in a way that makes souls-likes blush, or one that will make you the bane of any friend that pulls out the calculator on their phone: No Time For Math is for you.
