Qubric is a minimalist puzzle game for building quantum intuition. Solve bite-sized circuits by tapping gates, comparing state probabilities, and matching the target. Each puzzle teaches a small idea, from simple splits and flips to linked states, phase signs, and three-qubit proof routes. Play through the Journey, return for a daily challenge, earn XP and badges, and track your progress across your account. Qubric keeps the interface focused so the logic stays front and center: no ads, no tracking, no unnecessary permissions. Features: - 22 handcrafted quantum logic puzzles - Daily challenge with streak tracking - XP, levels, and badges - Clean visual comparison between current and target states - Account-based cloud progress - In-app privacy controls and account deletion Qubric is built for students, curious builders, and anyone who wants quantum computing to feel less abstract, one puzzle at a time.
