Monster Math is a subscription curriculum app for kids roughly K–5, built around a monster-collecting adventure and US Common Core number-sense skills. Math Games is built for adults sharpening skills they already have — no subscription, no monsters, just four fast games and your own numbers.

Ten levels a day is enough for a genuine daily habit and a real sense of the app before the trial nudge shows up — it's not a token teaser, and for a five-year-old that's plausibly a full session anyway. The catch is what happens on day two, three, and every day after: the same ten, then a wall, until the clock resets or a parent pays $59.99 for the year.
That's a reasonable way to fund six mini-games, ongoing content, and a free tier for every teacher who asks. It's just a different shape of "free" than Math Games, where there's no daily counter running in the background at all — not because we're more generous in spirit, but because there's no subscription business behind the games to fund with a paywall.
Monster Math's levels are graded to a K–5 school-year syllabus, which means the app is deciding where a child sits based on age and curriculum stage — appropriate for its job, since the player usually can't make that call for themselves yet.
An adult already knows roughly where they stand. Math Games skips the placement entirely: four tiers — Rookie, Amateur, Pro, Elite — and you pick, based on how the numbers feel, not on a grade you were assigned years ago.
