Rocket Math is a fact-fluency drill program schools and homeschoolers assign to students — timed worksheets and a digital version, tracked by a teacher. Math Games is the same timed-drill idea, minus the classroom: pick a level, play, see your own numbers.

Rocket Math's whole model assumes a teacher or parent is assigning it and checking progress — that's exactly right for building fact fluency in a structured program.
Math Games assumes the opposite: you open it yourself, for a minute, because you want to. There's no one assigning you a level or checking whether you finished it.
Rocket Math sequences you through specific fact families (like all the ×6 facts) until each is automatic — a proven approach for building raw recall in kids.
Math Games mixes all four operations together across four difficulty tiers, closer to how mental math actually comes up day to day — a bill, a discount, a quick estimate — rather than one operation at a time.
