TTac

The AppViewModel (navigation, celebrations, wiring) and the Match state machine.

Persisted state and the pure reducers that update it: records, streaks, medals, unlocks, heatmaps and the LAN board.

Sound effects synthesised from oscillators at startup, and haptic waveforms.

Pure Kotlin game rules: the Tic-Tac-Toe board and AI, the Blocks falling-block engine and the Word Hive generator. No Android dependencies, so everything here is unit-tested on the JVM.

LAN multiplayer: the line-delimited JSON protocol, NSD discovery, TCP sessions, aliases, session codes and QR join links.

The bouncy glass UI kit, drawn with Compose modifiers and Canvas.

Canvas drawing: marks, the board, heat effects, medals, arcade art, glyph icons and the animated backdrop.
