Island Bridge Builder

Island Bridge Builder is an original puzzle game designed for casual learners and game enthusiasts. Connect numbered islands with up to two bridges between neighboring islands. The full release includes 20 deterministic levels that can be replayed as often as you like. Bridge lines join consecutive islands horizontally or vertically. Every number must equal the total adjacent bridge count, and every island must be reachable in the network. Click or tap a dotted bridge segment to cycle between zero, one and two links. Solve islands with only one possible neighbor first. Keep the whole graph connected while balancing bridge totals. No online account, payments, remote game engine or subscription is required. The ZIP includes the HTML5 game, original artwork, implementation source, guidance and real gameplay screenshots. Installation is as simple as extracting the ZIP and opening game/index.html in a compatible browser. The included source files can be customized within the license terms. Browser compatibility beyond tested Chromium environments should be verified before marketplace publication.
