THE FORGE AWAITS
How Gridhammer Works
Gridhammer is a 1v1 card game played on a grid. Each card has four corner values (0–10)
that determine combat when placed adjacent to other cards. When your card's side sum is higher than the
opposing card's side, you capture it. Control the most cards when the board fills up to win.
CORNER COMBAT
Each card has four corners arranged in a 2×2 grid. When placed next to an enemy card,
the two touching corners are summed on each side. Higher sum captures the opponent's card. House matchup
bonuses can tip close battles by +1 or -1.
But raw numbers are only half the story. Every card can carry up to four abilities —
passive auras, placement effects, defensive reactions, and capture triggers — that reshape the battlefield
in ways pure math can't predict.
FIVE HOUSES
Choose Your Forge
Each house has a distinct playstyle, unique ability chains, and a house advantage cycle that creates
natural rivalries. Your deck is built from one house — mastering its strengths and covering its
weaknesses is the key to victory.
A rock-paper-scissors cycle gives +1 or -1 to combat when houses clash. Stillforge overpowers Stoneheart,
Stoneheart outlasts Embercrest, Embercrest outpaces Runeweaver, and Runeweaver dismantles Stillforge.
Shadowmine plays mind games from the margins.
61 ABILITIES
Four Slots, Infinite Combos
Every card can carry abilities in four categories. These aren't random effects — each house has
carefully designed ability chains that reward mastery and create deep strategic layers.
AURA
Passive effects active while on the field. Buff allies, protect corners, or suppress enemies nearby.
PLACEMENT
Triggers when played. Push enemies, swap positions, set hidden traps, or buff surrounding allies.
DEFEND
Reactions when attacked. Prevent captures, counter-flip the attacker, or root yourself in place.
CAPTURE
Triggers when you flip an enemy. Crush for bonus power, chain-flip neighbors, or draw extra cards.
Abilities are tied to card templates — every copy of "Anvil Sentinel" has the same ability, but
different corner values. Strategy comes from combining the right abilities with the right board positions.
Every card, every pack, every advantage is earned through gameplay. Win matches, complete quests, and
grow your collection at your own pace. The shop accepts only currency you earn in-game.
ORE SCRIPS
Earned from battles and quests. Spent on booster packs to expand your collection.
SLAG
Earned by recycling cards at the Smelter. Spent on forging new cards or rerolling corner values.
Every booster pack you open without pulling a Legendary increases your pity counter.
After 15 packs, a Legendary is guaranteed. The system resets on every Legendary pull.
QUEST CHAINS
Complete the Forge Your Path onboarding for starter rewards, then take on Forge Trials —
7 challenges that reward 2 Elite Booster Packs on completion.
DAILY QUESTS
Three rotating daily objectives reset each day. First Win, Play 3, Win 3 — quick earners
to keep your Ore Scrips flowing.
THE SMELTER
Don't need a card? Smelt it for Slag. Use Slag to forge cards from templates you've seen
or reforge corner values on existing cards.

SERVER-AUTHORITATIVE
All multiplayer game logic runs on the server. Corner values, ability effects, and flip outcomes
are validated server-side. The client displays results — it doesn't decide them.
NO PAY-TO-WIN
Crown Ingots buy cosmetics only. Every gameplay-relevant card and upgrade is earned through
playing. Skill and strategy determine the winner, not wallet size.
ANTI-CHEAT
The server re-executes every ability independently. Client-reported values are cross-checked
against server state. Tampered data is rejected and logged.
