Pattern Lock Decoder

Pattern Lock Decoder is an original puzzle game designed for casual learners and game enthusiasts. Deduce a secret combination of geometric symbols using partial feedback. The full release includes 20 deterministic levels that can be replayed as often as you like. Exact feedback counts symbols in the right position. Near feedback counts correct symbols in other positions without double counting. Attempts are limited; repeated symbols can appear in advanced levels. Tap each guess slot to cycle through six symbols and choose Submit Guess. Change only a few symbols between guesses so each response gives interpretable information. Save combinations with high Exact counts. 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.
