How it works
Kids start with Coin & Bill ID, where a short animated scene introduces each new idea right before it is needed, then pick from eight money games. They answer by tapping choices, tapping coins and bills into a purse, or nudging amounts with plus-and-minus steppers. Every answer gets instant feedback with a short explanation, and all the math is computed in exact cents. Each game awards up to three stars; signed-in players keep their best.
Kids can play without signing in; guest stars stay until you reload or close the page. A grown-up signs in once and adds a player for each kid, so CoinQuest's stars and progress save to your account and follow you to any device.
