The Diamond Mine

Read-only starter

The Diamond Mine is intended to expose the deeper machinery of Tetgame Rabbots: behavior files, scoring nudges, strategy filters, voice loaders, backups, and eventually safe editing tools.

/*
 * Tetgame Rabbot: Aquila Talon
 *
 * Personality v3: Aquila's choice brain lives here. Her voice lines
 * live separately in js/voices/aquila_talon.json and are registered by
 * js/voices/aquila_talon.js. Tetgame supplies the legal move lists in
 * ctx.tokenMoves and ctx.tetMoves, and this file simply chooses among them.
 * No DOM, Babylon, or save/load dependencies.
