Arrows want to leave the harbor. When a head touches a tail of the same color, it inherits the path the arrow ahead took, and they leave together. That's the whole game in one line. And that one line produces 965 different puzzles. โ–  One rule, learned once Tap an arrow and its whole body slides toward the head. A body bent like a hook retraces the path it came along, and corners hold their spot until the tail passes through. Match colors and the path connects. That's everything you need to know. โ–  All 965, checked by machine Every one of the 600 campaign routes and 365 daily routes was machine-verified: each has a solution that finishes within its move limit, and that solution uses no hint, no undo, and no payment. Hints and undo are shortcuts for when you want to move faster, not requirements to pass. A stuck moment means there's a move you haven't spotted yet, not a moment that needs money. โ–  Nothing to lose on a failed attempt Restarting is always free. Undo comes with 3 free uses per route. Life caps at 5 and refills automatically, one every 30 minutes. โ–  600 campaign routes, 365 daily routes The campaign spans 20 harbors, 30 routes each. Boards widen and colors multiply as you go. Daily routes bring a fresh puzzle every day. The first five routes ease you into the rules, so take your time there. โ–  A quiet screen Cream and teal tones, a wooden harbor. No flashy effects, no countdown pressure. Spending a long time on one puzzle is exactly how this game is meant to be played. Interstitial ads don't appear during your first 10 routes. A one-time purchase removes interstitial ads for good; rewarded ads you choose to watch stay available.
