Long Backgammon

Long Backgammon (Russian Nardi / Длинные нарды) is a classic tactical board game crafted natively for Linux and GNOME with GTK4 and Libadwaita.

Compete to bring all 15 checkers into your home board and bear them off before your opponent, relying on strategic foresight, smart positioning, and dice management.

Key Features:

• Single Player vs AI: Challenge the computer across two distinct difficulty tiers — Casual and Grandmaster.
• Local Two-Player Mode: Play against a friend on a single computer (Hotseat).
• Authentic Rules: Strict one-checker-from-the-head rule (with opening double exceptions for 3-3, 4-4, and 6-6), opening roll-off, and strict 6-point prime blockade enforcement.
• Official Match Scoring: Accurate tracking for normal victories (Oin), Mars (gammon), and Home Mars (backgammon).
• Modern GNOME Design: Fluid animations, authentic Wood and Marble visual themes, and 3D dice rolling physics.
• Intuitive Controls: Drag & drop checkers with magnetic snap, customizable dice cursor, and move trajectory preview arrows on hover.
• Quality of Life: Full undo support, real-time move history log, auto-save on exit, customizable game speeds, and rich sound effects.
