Spreadlock
Contain the outbreak
Objective
Find hidden infected cells and stop the outbreak before containment fails.
How A Turn Works
- Each scan or quarantine action uses 1 action.
- When Spread In reaches 0, infection spreads from infected cells to nearby hidden, unquarantined tiles.
- Quarantined tiles block spread.
Controls
- Left Click / Tap: Scan (reveal) a tile.
- Right Click: Place or remove quarantine on a tile.
- Quarantine Toggle Button: On mobile, enable quarantine mode then tap tiles.
- Pause: Freeze timer and gameplay.
- Music: Mute or unmute soundtrack.
Reading The Grid
- Numbers show how many infected neighbors are in the 8 surrounding tiles.
- A 0 clue triggers an automatic safe-area cascade reveal.
- Your first scan is always safe.
Win Conditions
- Quarantine all infected cells, or
- Reveal all safe cells.
Lose Conditions
- Containment meter drops to 0, or
- Infection grows beyond 25% of the grid.
Scoring Tips
- Safe reveals and zero cascades build score quickly.
- Correct quarantine placements give bonus points.
- Wrong quarantines, infected reveals, and spread events cost points.
- Finish faster for a bigger time bonus.
