Sandbox is a custom game mode where players can rework their owned RISK maps, then play and share them online.




Sandbox users will have access to a powerful new tool for making and sharing original creations. It can be accessed via the following two tabs:

  • Sandbox Tools: Map Editor
    Remix any map you own into a custom Sandbox map. Creations can be published, shared, and hosted online.

  • Sandbox Maps
    Save and access your collection of custom sandbox maps, host Sandbox games that are available to join for all players — whether or not they are subscribed.



What can I edit in the Sandbox Map Editor?

The editor launches with a deep set of tools, with even more planned for 2026.

  1. Unlock and control map modifiers:

    1. Fog of War

    2. Blizzards (quantity & exact placement)

    3. Portals (quantity & exact placement)

  2. Set continent bonuses for each continent

  3. Customize Territory Cards:

    1. Experiment with new card modes and modifiers:

      1. Progressive: troop bonuses grow by a flat value each trade
        Exponential: troop bonuses grow much faster than progressive
        Per-Player: troop bonuses only grow on your own trades (progressive or exponential)
        Fixed: define custom values for each set type

    2. Define how many bonus troops are given for owned territories

    3. Define how many Wild Cards are shuffled into the deck

    4. Define initial trade-in values and growth rate for ‘Progressive’ and ‘Exponential’ modes.

  4. Adjust Starting Troops:

    1. Default: current behaviour based on player count.

    2. Dynamic: new behaviour based on the number of unblocked territories.

    3. Custom: define starting troops per player count.

    4. Add custom multipliers to troop numbers in Default or Dynamic

  5. Save, playtest, publish, and share:

    1. Host games on your Sandbox maps

    2. Save maps via in game link or Map Code

    3. Duplicate maps and make your own variations

    4. Playtest your maps in-editor before publishing

Track stats like plays and likes on your published maps



How do I gain access to Sandbox?

Sandbox is available as a subscription. For a small annual fee, you can bring any map you’ve purchased or unlocked into the Sandbox Map Editor.


From there, you can adjust things like Portal placement, Continent bonuses, Territory Cards & Starting Troop rules, and much more.



After you’re happy with your map, you can playtest, publish it and share with the wider community. All other players, including those who aren’t subscribed can jonin hosted games on your Sandbox maps. Other Sandbox creators can save your maps to play later, share or even duplicate and remix their own version of your map.
