Tideline: Light Puzzle

Tideline is a calm puzzle game about steering colored light. A sleepy harbor has gone dark. Turn mirrors, place glass, and send each beam to the lighthouse, lamp, or buoy that is waiting for its color. When the light arrives, the harbor wakes up. SAIL ISLAND TO ISLAND Every level is an island on your sea chart. Solve one and your boat sails on to the next. Reach the end of a place and the storm over the next one parts. A NEW IDEA IN EVERY PLACE Mirrors in the Harbor, stones you place to shield the Breakwater, splitters in the Channel, filters in the Glasshouse, prisms at the Lighthouse, combiners in the Estuary, placing your own pieces in the Workshop, and everything at once on the Open Sea. The Harbor Master explains each new idea the first time you meet it. DAILY LIGHT One new puzzle every day, the same for everyone. Beat par, keep your streak, and share your result without spoilers. FRIENDS ON THE WATER Seals lounge on the rocks, puffins stand on the pier, otters float in the estuary, a crab scuttles on the sandbar, and now and then a whale comes up to say hello. MADE FOR ONE THUMB Tap to turn and drag to place. No timers and no ads. FIVE LIVES The Harbor is yours to learn in, free. After that, each level gives you a few moves beyond par. Run out and you lose one of five lives, and they come back one every twenty minutes. PEARLS Earn Pearls as you solve levels and play the Daily Light. Spend them on an undo that gives the move back or a hint, buy a few more moves when the tide runs out, or save up for a new board theme. • 120 hand-picked levels across eight places • Three stars for solving at or under par • Game Center: a Daily Light leaderboard, a stars leaderboard, and 16 achievements • Colorblind mode adds patterns and shapes to every color • Drawn entirely in code, with gentle synthesized sound and haptics Optional in-app purchases: Pearl packs, board themes, the Deep Water chapter pack, and a Supporter bundle. The Daily Light never uses hints, lives, or anything paid.
