Nine cells. Two clues each. One world a day. Geo Grid is a daily geography puzzle for the quietly competitive. Each day you get a 3×3 grid where every row and every column carries a clue — a continent, a population threshold, a shared border, a language, an island, and more. Your job: fill every cell with a country that satisfies BOTH its row clue and its column clue at the same time. You have ten guesses, and everyone plays the same daily board. Here's the twist: obscure-but-correct answers score lower — and in Geo Grid, lower is better. Anyone can place the obvious country. Can you find the clever one? 【A puzzle every day】 One shared global puzzle daily, with a live countdown to the next edition and a streak to keep alive. 【Play as much as you like】 Can't wait for tomorrow? Unlimited practice deals a fresh board any time, across Easy, Medium and Hard. 【Built for map lovers】 Clues span continents, population, area, borders, languages, landlocked nations and islands — drawn from real-world data for nearly 200 countries. 【Earn your marks】 Keep daily streaks alive and unlock 23 achievements, from your very first grid to globe-trotting milestones. 【Share the result】 A clean, spoiler-free result card friends can read even if they haven't played — then challenge them to beat your score. 【Yours, your way】 A warm editorial "almanac" look in light or dark, gentle sound and haptics, and a hint for when a cell has you stumped. Geo Grid is free to play. An optional one-time purchase removes ads and unlocks unlimited hints — yours forever, never a subscription. Today's grid is waiting. How well do you really know the world? 【Terms of Use (EULA)】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: pgmMasterCode at none against Geogrid's 1. pgmMasterCode also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.0). Geogrid's advantage is update cadence (every 2 weeks vs every 14 months). On price and device support there is nothing between them.
