Agar.io review

Agar.io is the game that made .io a genre, and it still plays the same way. The site invites you to control your cell and eat other players to grow, with millions of players worldwide trying to become the biggest cell. Miniclip's App Store listing adds the tactics: split to catch smaller cells, shrink and dodge to avoid bigger ones, and type certain usernames to get secret skins. The browser game is free; the iPhone and iPad app is free with in-app items from $1.99 and a VIP subscription at $7.99 per week on the US App Store, which is steep for a casual game. The listing also notes optional purchases that include random items. Agar.io ranks mid-table because the rules are timeless but the feature set is thin next to Krunker or ZombsRoyale.io. It is a strong pick for anyone who wants the original. We compared documented features and published prices.
