The keeper’s challenge

Simple rules. A kingdom of deductions.

Every puzzle has one unique solution. Progress comes from logic, careful marking, and the occasional spark of insight.

One forge in every line

Place exactly one forge in each row and each column. A completed board balances every line.

One forge in every region

Matching emblems mark connected regions. Each region must contain exactly one forge, no matter its shape.

Forges never touch

Two forges cannot touch, including diagonally. Use every safe cell you uncover to narrow the next move.

Travel the Forge Road

Follow a chaptered campaign through changing lands, learn new deductions, and earn mastery as each Trial is restored.

Rebuild the Kingdom

Bring home blueprints, relics, and Forge Sigils. Each expedition returns something useful to the settlement and its Keeper.

Return to Free Forge

Step beyond the campaign with replayable trials across multiple board sizes and difficulties.
