Build your path. Break theirs. Qu is a relaxed but razor-sharp tile game where every move shapes the board. Extend your own path or cut off your opponent's in a battle of timing, tactics, and bold decisions. Learn fast. Think deeper. A hands-on tutorial walks you through tile placement, orientation, and scoring right on the board. Beneath the simple rules lies a game of strategy, psychology, and long-term planning. One puzzle. One shot. Everyone. The Game of the Day gives every player the same board and the same tiles, once a day. You get a single attempt against the GPA AI, so every placement matters. Climb the daily leaderboard, check how friends did, and share a spoiler-free result that never reveals the solution. Every match feels new. Face the GPA AI on Easy or Medium, challenge a Game Center friend directly, or match with a rival online. No two games play the same. Choose your mode. Choose your board. • Take on the Game of the Day — one shared daily puzzle for the whole world • Play Small, Large, or Advanced games online • Play Easy or Medium against the GPA AI • Start a game with a friend through Quick Play Tap to rotate. Drop with intent. Tap any tray tile to cycle through the orientations that actually fit, then place it. A live count shows how many tiles you have left. Stuck with a bad draw? Swap your whole tray for a fresh one. Outmatched? Propose a concede, or resign and move on. Talk trash. Take it too. Every match carries its own message thread. Send a jab when you pull ahead, own it when you don't — the conversation lives right alongside the board. Climb the leaderboard. Keep your streak alive. Play every day to build your streak and rise through the ranks. Your lobby keeps a daily podium, a streak board, and a month-long score graph — all in one swipe. The graph now races the month's leaders against last month's finishers so you can see if you're beating your own pace. Every rank carries its own color, from Gold at the top down to Chartreuse. Relive the win. When a match ends, Qu replays the board move by move and breaks down exactly how the score was won. Then run it back with a rematch. Simple to start. Hard to put down.
