EQU8 is the equation board game that makes math feel like a strategy game. Place digit and operator tiles on a 15×15 board to build valid math equations — and outscore your opponent before the bag runs out. Think Scrabble, but with numbers. HOW IT WORKS Select tiles from your rack and place them on the board to form a valid equation. Score points based on the tiles you play. Land on a Double Digit or Triple Equation square to multiply your score. Connect to existing tiles to build perpendicular equations and score even more. 4 DIFFICULTY MODES Beginner (ages 6+) uses addition only. Early Math (ages 7+) adds subtraction. Intermediate (ages 9+) brings in multiplication. Full Game (ages 11+) includes all four operations. Start simple and level up as your players grow. NEW: WEEKLY CHALLENGES Four fresh puzzles every Sunday, one per mode. Each has a preset board and rack. Find the one move that hits the goal, such as an exact score or using all 7 tiles.

Verdict
The clearest difference is ads: Equ8 at none against Number Sum's shown. Equ8 also leads on rating (5.0 vs 4.6). Number Sum's advantage is ratings volume (2.3K vs 3) and iOS requirement (12.5 vs 16.4). On price, update cadence, 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. Number Sum sells 5 one-off in-app purchases and Equ8 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Equ8 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Number Sum has 2.3K ratings behind it against 3, so its average is the more settled of the two.
Number Sum ships an update fortnightly, Equ8 every 9 days. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
