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.
