A calm logic puzzle about a journey downstream. Pebble, a little coral fish, swims from a mountain spring to a warm lagoon, and you clear the way: fill the water so every number becomes a patch of dry land with exactly that many tiles, each patch holds one number, all the water flows as one, and no 2×2 pool appears.
Pebble, the guide
Pebble cheers, frets and comments on your moves, from a gentle "that tile is water" to a happy leap when a puzzle is done.
The kingfisher on the high branch
The Journey path winds through eight chapters, one per grid size from 5×5 to 12×12: The Spring, Fern Rapids, Willow Bend, The Oxbow, Heron Lake, Reed Marsh, Mangrove Delta and The Lagoon. Each chapter has eight puzzles and a short story, and the next opens after four.
The herons in the shallows
Patient tools for a patient bird: choose Water or Land, tap or drag along a row, undo, and use three lifebuoys per puzzle that each reveal a tile. Check shows which tiles need another look. Three stars come with no lifebuoys and no slips.
The reeds at sunrise
Daily challenge: one shared puzzle each day, 6×6 to 9×9, with a streak drop and a Monday-to-Sunday strip.
The fiddler crabs of the delta
Collection: six board themes – Lagoon, Coral reef, Mangrove, Sandbar, Night swim and Kelp forest – and twelve stamps, all opened through play.
The old willows
Lore: a quiz of 26 real facts about the great waterways and lakes of the world, eight questions a round, with a fact card after each answer.
The ferns by the rapids
Settings hold haptics, how to play, a progress reset and the animated background: soft light on the lagoon, ripple rings and leaves turning as they drift. Switch the animation off for a still screen.
