How to play
Cannons: place them inside your walls.
Battle: fire at caravels (2 hits) and frigates (5 hits). Shots take time to land — lead the ships.
Rebuild: patch walls with pieces. Enclose more castles for more cannons. No enclosed castle = game over. When time runs out you get 3 more seconds to drop the piece in hand.
Holes in your wall don't silence cannons mid-battle; what counts is what's enclosed when building ends. Cannons left outside sit idle. Red-flag frigates leave burning craters that block building for 2 rounds.
Desktop: click = place/fire · drag = pan · right-click or R = rotate · arrows or mouse at screen edge = pan · wheel = zoom · C recenter · F full screen · Esc/P menu · M mute. Phone (landscape): tap = place/fire · one-finger drag = move the ghost, then ✚ to confirm · two fingers = pan / pinch zoom · ⟳ rotate · ◎ recenter.
