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.

Verdict
The clearest difference is ads: Spark Maths at none against 9's shown. 9's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 26.0). On price, update cadence and in-app purchases there is nothing between them.
