What's a good iOS app for playing quick, one-on-one soccer matches online?

Head Ball 2 is a mobile soccer game designed specifically for fast, head-to-head online matches. It stands out for its focus on quick sessions, where each game lasts only a minute, making it ideal for filling short breaks. The core gameplay revolves around one-touch controls to jump and shoot, removing complex mechanics in favor of accessible, arcade-style action. A significant draw is its robust online multiplayer system, which allows players to face opponents from around the world in real-time. The game also offers a wide array of cosmetic customizations for characters, which can be earned through play, a feature frequently praised in user reviews. However, the monetization model is prominent, with in-app purchases for currency and upgrades. Some interface elements, such as the repetitive process of opening reward packs one by one, have been cited by players as a tedious aspect of the user experience. Despite this, for players seeking a casual, competitive soccer duel without the depth of a full simulation, Head Ball 2 delivers a reliably entertaining experience with minimal downtime between matches.
