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.

Verdict
The clearest difference is ratings volume: Scratch Inc. at 1.9K against Equate 8's 12. Scratch Inc. also leads on review sentiment (93% vs 75%) and update cadence (every 4 days vs weekly). Equate 8's advantage is rating (5.0 vs 4.7) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Equate 8 sells 1 one-off in-app purchase and Scratch Inc. sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Equate 8 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Scratch Inc. has 1.9K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 75% of Equate 8's written reviews are positive against 93% of Scratch Inc.'s, so the app with the better star average is not the one people write more warmly about.
Equate 8 ships an update weekly, Scratch Inc. every 4 days. The most recent releases landed on June 3, 2026 and September 28, 2026 respectively.
