Equate 8 is a bold reimagining of the classic magic square—an innovative, addictive math puzzle featured at New York City’s Museum of Mathematics. Players rearrange numbers in a 3×3 grid to balance eight equations at once (three rows, three columns, two diagonals), racing to solve the puzzle in the fewest moves. With multiple operators, escalating difficulty levels, and medals awarded for efficiency, Equate 8 is as rewarding as it is challenging. Equate 8 is the sequel to our Webby-nominated game The Devil’s Calculator, named one of PAX’s 10 Best Indie Games of 2019. Disguised as a casual mobile game, Equate 8 is a powerful interactive learning tool. Our talk will explore the sophisticated math behind the project and debut a new feature allowing educators to design levels aligned with their curricula. With its blend of pedagogical depth, intuitive design, and playful challenge, Equate 8 shows how games can transform math education. It empowers students, supports teachers, and makes math feel like play. Solving the grid in fewer moves will gain a silver or gold medal, but a bronze is awarded regardless, so don't stress. The daily puzzle gives players a free way to play and unlock content. Acquire “streaks” tokens by playing regularly. Exchange medals and streaks for Challenges, packs of themed puzzles. If the squares seem too complicated, open the menu to try Snap Mode. A number will automatically be locked (circled) when in the correct place. This mode can be played in a limited number of sequences before it reverts to the default.
