Only for iPhone

iPhone

Turn paper mirrors, trace golden beams, and light every window across 40 original puzzles. Guide one ribbon of sunlight through a tiny paper town. In Sunthread, every mirror changes the beam’s direction. Rotate the folds, study the route, and light each marked window before your Sun Pulses run out. Plan your path, then send the light. Explore 40 distinct levels across five paper-crafted districts, from Apricot Rooftops to Moonpaper Observatory. Each board features a different arrangement of mirrors and windows, while new targets and tighter pulse budgets gradually raise the challenge. Make every pulse count: • Rotate paper mirrors to bend the beam. • Preview the trail before you fire. • Light multiple windows in one pulse to build a Combo. • Earn score bonuses by solving levels with pulses to spare. Keep a record of your journey: • Track completed levels, pulses, and your personal best on this device. • Earn five badges as you reach milestones. • Check in once a day for Sun Coins in the seven-day reward calendar. Warm colors, soft animations, and paper-craft visuals make Sunthread a cozy logic game to enjoy at your own pace. No music or sound effects—just a quiet little town waiting for its next bright idea. Fold the paper. Find the light.
