PUZZLES

Math puzzles for all ages and skill levels.

JRMF puzzles are unique compared to other math games you’ll find. We design problems with low-floors so everyone can get started by the simple act of trying something and with high-ceilings that lead to challenging mathematics.

Play them in person with friends, or virtually at home.
