Multiplayer Worlds

Multiplayer Overview

Stamp Collector Simulator is an MMO — you play in shared persistent worlds alongside other players. Everything happens in real time on the same server.

Joining a World

1. Create an account (email or Google OAuth)
2. Browse available worlds or create a new one
3. Join a world to start your game in that world’s shared space

Limit: You can have active games in a maximum of 2 worlds simultaneously.

What’s Shared

In the Same World

• Adversaries — all players share the same adversary states. If someone triggers an adversary’s wake condition, it wakes for everyone.
• Leaderboard — top 50 players ranked by stamps (60-second cache)
• World Chat — real-time messaging with all players in the world
• Direct Messages — private communication between players
• PvP Attacks — players can launch network attacks against each other

Per Player

• Game state — your cards, resources, threads, and permanents are yours alone
• Contacts — your list of known players and adversaries
• Progression — independent of other players

Leaderboard

The world leaderboard shows the top 50 players by stamp count, refreshed every 60 seconds.

There’s also a global leaderboard that tracks maxStampsAchieved — your all-time highest stamp count across all worlds. This persists even if you lose stamps.

World Chat & DMs

• World Chat — visible to all players in the world
• Direct Messages — private conversations between two players
• Requires being in the world to access

PvP Dynamics

In multiplayer worlds:

• Use Network Scan to discover the top 10 stamp holders
• Use Backtrace to identify who’s attacking you
• Launch hack spells to disrupt competitors
• Higher-ranked players attract more attention

See the PvP Guide for detailed attack and defense strategies.

Adversary Interactions

Since adversaries are shared:

• Someone else can trigger them — a rich player joining your world can wake adversaries for everyone
• Anyone can kill them — damage from all players accumulates
• Whitelist is personal — your Favor From Above only protects you, not other players
• Kill rewards go to the killer — whoever deals the final blow gets the stamps and money

Deleting Your Game

You can delete your game in a world at any time:

• DELETE /games/:gameId
• All your game data is removed
• If you were the last player, the world is automatically deleted

Tips

• Watch the leaderboard — know who’s ahead and who might be a threat
• World chat is valuable — coordinate with other players against adversaries
• Choose worlds carefully — a world with established high-stamp players means adversaries are already awake
• 2-world limit — use your second slot for experimentation or different strategies
