About

Forge your strategy. Shatter your rival.

GridHammer is a head-to-head tactical battler set in a world of dwarven forge masters. Two players share a 5×5 grid and a common pool of 45 metal plates. Every plate has four sides, every side has a value from 2 to 8, and every placement is a decision that can cascade into devastating combo chains — or a catastrophic misread.

No luck. No loot boxes. Pure positioning.

Five houses of master smiths — Stillforge, Runeweaver, Embercrest, Stoneheart, and Shadowmine — each contribute 9 plates to a shared forge pool. Both forge masters draw from the same pool. You start with 6 plates in hand and draw a new one after every play. The strategy isn’t what you get — it’s where you put it.

Directional combat

Every house distributes its power differently across four edges. Embercrest dominates from above. Shadowmine crushes from below. Stillforge anchors from the left. Stoneheart locks down the right. Runeweaver stays balanced with no exploitable weakness. A low-tier plate in the right position captures a high-tier plate in the wrong one.

The Hammer

Every seven turns, the hammer falls. All plates on the board lose one durability. Every plate starts with 3 durability — Hero, Rare, Common — and plates that break shatter and recycle back into the forge pool. Timing your placements around the slam is as important as reading your opponent.

Forge Essence

Each forge master carries a vial of 30 Forge Essence. Every capture drains 1 from your rival’s vial. Shatter a plate and it drains 2 instead. Reduce their vial to zero and the battle is over.

Combo chains

The five houses form a combo ring. Capture a plate whose house your house dominates, and the captured plate re-checks from its new position — cascading into chain captures that can flip the entire board.
