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. The clock starts when you tap Start. Race other players on weekly leaderboards, use hints if you're stuck, and keep your week streak alive. PLAY YOUR WAY Pass and Play lets two players share one device. Online play lets you challenge anyone and take turns whenever you want. Friend Challenges let you invite a specific player. Matchmaking pairs you with someone at your skill level using a full Elo ranking system. CPU Mode — challenge the computer in Easy, Medium, or Hard. Your computer Elo rating improves as you get better, and the difficulty grows with it. Free players get Levels 1 and 2. Pro unlocks all four modes against the CPU.

Verdict

The call

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.
