Equate 8 vs Lights Out Infinity

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.

Lights Out Infinity — a modern remake of the 1995 handheld classic, built for iOS. Tap a light and its four neighbours flip with it. Turn every light off. One rule to learn, three hundred puzzles to master. WHAT MAKES IT SPECIAL Every level carries a proven minimum. Not an estimate — a number checked by a solver that searched every valid solution, so matching it means you played that board perfectly. The hint always lies on an optimal path, and the stars measure how close you came. 300 HAND-BUILT LEVELS 150 classic and 150 hexagonal, from 5×5 grids up to 7×7, and from small hex boards to large. Symmetric patterns throughout — no random layouts. Up to 3 stars per level. HEXAGON MODE Six neighbours instead of four. The same rule produces strategies that simply do not exist in the square game, and no other Lights Out app has it. INFINITY MODE Pick a grid from 5×5 to 10×10 and a difficulty, look the board over before you start, and reroll until you like it. Every board is solvable, and its target move count is exact. DAILY CHALLENGE One puzzle a day, the same for every player worldwide. Track your run on a constellation calendar and compete on the Game Center leaderboard. 8 VISUAL THEMES Four free — Classic, Cosmic, Ocean and Monochrome. Four premium — Midnight, Aura, Amber and Moss. Monochrome is free on purpose: it is the most readable of the eight, and readability is not for sale. SMART HINT SYSTEM Stuck? The hint ring breathes over the cell to press, and it always sits on an optimal path. Three free hints per level. NEW TO LIGHTS OUT? A short tutorial teaches the rule inside a real board — three sentences, three moves, nothing to read through first. ACCESSIBILITY VoiceOver throughout. Every colour on every board measured against contrast thresholds. Full iPad layout. Seven languages, switchable inside the app. GAME CENTER 2 leaderboards and 16 achievements with custom artwork. PREMIUM PACK — ONE PURCHASE, FOREVER Hexagon levels 51–150, Infinity grids up to 10×10, unlimited hints and 4 premium themes. Family Sharing enabled. No subscription. No ads. No tracking. Works offline. Just puzzles.
