One forge in every line
Place exactly one forge in each row and each column. A completed board balances every line.
Forgedoku
Restore a kingdom, one forge at a time.
Read the regions, rule out impossible cells, and reveal every hidden forge. Journey along the Forge Road, rebuild the Kingdom, and return for fresh Free Forge trials.
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 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.
Local play with platform recovery
Create up to six local forge profiles and keep playing offline without a Lowkey Forge account. When available, iCloud or Play Games Cloud Save can recover profile and completed progress data; active puzzles and Supporter Pack purchases are handled separately.
Profiles marked 13–17 or 18 or older may receive non-personalized, G-rated ads after the relevant progression unlocks. Rewarded ads always require player action. Prefer not to say receives child treatment and no ads, and the optional one-time Supporter Pack removes banners.
