## What is 9?

Math boring? Give this five minutes.
9-Box trains times tables from 1 to 9. Kids get it immediately. Adults discover they're rustier than they thought.
The grid has 9 blocks, 9 squares each, 81 problems total. Each block has a big background number. Each square has its own number. Multiply them, type the answer. Simple to understand, embarrassing to mess up under pressure.
Five modes
Plus+ shows you which square to solve next, a nudge for beginners. Pro removes all help: just you and 81 problems.
Speed Run ends the moment you make one mistake. Your best time and your best attempt are saved separately, which creates a different kind of pressure than a simple high score.
Table Select lets you pick one table or a few, useful when you know exactly where you're losing time.
Mixed Sprint is 30 random problems from all tables. Done in a few minutes.
Progress
Each mode saves your best time, your previous time, and total games played.
