Castoff: Harbor Logic Puzzle
Untangle Boards, Beat the Tide
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The puzzle where the water moves.
Every board starts as a tangle. Then the tide turns. Castoff asks two questions: which line can leave first, and can it leave right now?
Tap an arrow and it runs off the board along its own path, as long as nothing is in the way. Hit something and you lose a heart. Read the board, work out the order and clear the water.
THE TIDE TURNS
From level 3, sandbars stop arrows at low tide and slip under the water at high tide. The tide turns every time 3 arrows leave, so the order you choose decides what opens next.
Can't move? Wait for the tide. It costs a flag but never a heart, so you can always finish a board. Find the right order and you never need to wait.
NEW RULES AS YOU PLAY
Each new piece arrives with its own rule:
• Flares launch up to three more free arrows
• Anchors hold the way until enough arrows have left
• Barges need all three lanes clear
• Whirlpools swallow any arrow that reaches them
• Canals bend an arrow's path, and their walls stop it
• Tunnels send an arrow out of their twin, same heading
ROUGH WATER
From level 10, every 5th level is a Rough level with only 2 hearts. Plan before you tap.
DAILY CHARTS
From level 6, a new picture puzzle waits every day. Complete it to add to your chart count.
