Scorehammer keeps score for Warhammer 40,000 games with the GDM 2026 missions. It is free and needs no account. Your games are saved in this browser only.
Before the battle
- Setup: enter both players, pick each side’s Force Disposition (this sets the Primary Mission), choose Tactical or Fixed Secondaries, tick Battle Ready (+10 VP) and choose who plays first.
- Swap if left and right on screen don’t match the table.
Each turn
- Primary: tap a tier’s VP button when you score it; tap it again to take it back. Tiers that can’t score right now are greyed out with the reason. Tap the mission name (or a Secondary card name) for its rules.
- Tactical Secondaries: at the start of your Command phase draw two cards, with Random or by picking the card you drew and pressing Draw. Cards you don’t score stay active, so you can hold more than two. You can draw two per turn; once per battle you may discard one and draw one more (1 CP). Score a card with its VP buttons (it is then discarded), or Discard one you give up. A card drawn by mistake: Undo.
- Fixed Secondaries: pick your two cards once; they stay for the whole battle.
- Next ends the turn, Back steps back. The row of boxes at the top shows every turn of the battle: the arrow points to the player whose turn it is. Tap a box to go to that turn; scores are not changed.
Fixing mistakes
- Undo reverses the last action.
- In Sequence of events, Edit changes a score event’s VP or note, and Undo / Revert goes back to just before that event.
Limits the app keeps
Primary and Secondary: at most 15 VP each per battle round and 45 VP each per game (end-of-battle Primary is not limited per round). A Fixed card scores at most 20 VP. Battle Ready adds 10 VP. 100 VP in total.
On a phone
Swipe sideways, on a player’s card or on the cards below it, or tap the Left/Right tabs to switch players. Back, Undo and Next sit at the bottom (and Talk, once an AI key is set). More holds Swap, Finish, Reset and About (on phones also Setup).
AI and voice (optional)
Under AI, add your own free Gemini key. Then hold Space (computer) or Hold to talk (phone) and speak, or type in the AI console, for example “Drew Cleanse and Beacon”, “Scored 8 primary” or “Right player discards Outflank”. Refer to an event by its number to correct the AI (“Delete event 4”). Your key stays on this device and is only sent to Google.
Games
Games lists your saved matches to load or delete. New saves the current match and starts another. Finish marks a match as completed (press again to reopen). Reset sets the current match back to Round 1 with 0 VP.
