How to Play Rampart
Quick start
Build walls around one or more castles during the timed construction phase, then place cannons inside the enclosed territory. In battle, aim ahead of moving ships and concentrate fire to sink them before they breach too many walls. During repair, close a complete loop around a castle first; extra territory matters only after survival is secured.
Controls
D-pad: move the cursor. A: place a wall piece, cannon, or fire at the selected target. B: rotate the current wall piece or cancel. C: confirm or use the alternate build action according to phase. Start pauses. Construction, battle, and repair are timed, so complete the smallest valid enclosure before expanding.
