Puzzle Realms
Select an expedition realm below. Each world presents a self-contained 40-puzzle staircase ascending across 4 distinct phases (Foothills, Ascent, Ridge, Summit) from 400 to 2200+ Elo.
The Frosted Citadel
Atop the frozen summits, tactical precision is preserved in crystalline ice. Master the 40-step ascent through freezing blizzards to claim the Glacial Shard.
The Obsidian Forge
Forged in subterranean magma, these brutal combinations shatter stubborn fortresses with crushing sacrifices.
Kyoto Sanctuary
Peaceful zen stone gardens harboring razor-sharp tactical lines. Quiet moves and geometric deflection bloom like cherry blossoms.
Neon Metropolis
High-voltage grid matrices and glowing neon channels. Calculating speed-demon combinations at the speed of fiber optics.
How Realm Expeditions Work
Hidden Tactical Motifs
During calculation, tactical theme tags remain strictly hidden to simulate real tournament conditions. Once solved, motifs (e.g. Deflection + Back-Rank) are unveiled with animated flair.
Stockfish 18 Refutation
If you play an incorrect move or tactical blunder, Stockfish WASM calculates and plays the punishing counter-move on the board immediately so you see exactly why your line failed.
3-Part Modular Armory
Clearing Phase II and Phase IV unlocks unique Finials/Heads, Stems, and Plinth Bases that you can equip to forge your custom Piece Persona avatar in The Armory.
