Section 6: Variants & House Rules
Risk is highly adaptable. Select variants before setup and apply them equally to everyone. Avoid changing reinforcement values, card rewards, or victory conditions after players have committed to a strategy.
Two-Player Neutral Army
Divide the territory cards into three roughly equal groups: one for each player and one for a neutral army. Place one army of the appropriate color on every dealt territory. Players then alternate placing their remaining starting armies on their own territories and neutral armies on neutral territories until the agreed supplies are placed.
The neutral army does not take turns, attack, receive cards, or gain reinforcements. When a player attacks a neutral territory, the opposing player rolls its defense dice. Neutral territories are conquered normally. The first player to eliminate the other active player wins; controlling the remaining neutral territories is unnecessary.
Capital Risk
After setup, each player secretly selects one controlled territory as a capital and then reveals all capitals together. A capital should begin with an agreed defensive force, commonly at least five armies. To win, a player must control every capital at the end of their turn. For a shorter game, require control of the player's own capital plus a majority of all capitals.
Territory Target
Instead of total conquest, the first player to end a turn controlling an agreed number of territories wins. Twenty-four territories creates a familiar medium-length target. For a tougher finish, require the player to hold the target through every opponent's next turn before victory is confirmed.
Progressive or Flat Card Rewards
The escalating trade schedule creates dramatic late-game swings. For a steadier game, every valid set may be worth a fixed number such as eight armies. Another common schedule awards four armies for three infantry symbols, six for three cavalry symbols, eight for three artillery symbols, and ten for one of each symbol. Wild cards complete any set but do not add a separate bonus.
Limited Card Escalation
Use the classic 4, 6, 8, 10, 12, and 15 sequence, but cap all later sets at 20 armies. This preserves the value of collecting cards while reducing sudden runaway turns.
Adjacent Fortification
A strict fortification game permits the end-of-turn move only between directly adjacent friendly territories. This makes interior positioning more important and slows the movement of large armies across a continent.
Multiple Fortifications
For a faster and more flexible game, permit up to three fortification moves at the end of each turn. Each move must independently follow a friendly path and leave one army behind. A particular army may move only once during the fortification phase to prevent unlimited shuffling.
Simultaneous Planning
To reduce waiting, other players may plan while the active player acts. No pieces or cards may be moved out of turn, and all decisions remain changeable until that player's turn begins. Dice rolls and battles must still be resolved one active player at a time.
Turn Timer
For brisk recreational play, allow two or three minutes for the attack phase. When time expires, finish the current dice comparison, then proceed to fortification. Pause the timer during genuine rules questions or when pieces must be recounted.
Team Play
Divide players into equal teams, with teammates seated apart when possible. Players retain separate territories, armies, cards, and turns. Teammates may coordinate openly but may not transfer territories, armies, or cards. A team wins when its members collectively control the entire board or satisfy the agreed team objective.
Friendly Casual Play
- Allow a player to correct an obvious piece-counting mistake before the next dice roll or turn begins.
- Roll dice in a clear area and reroll any die that leaves the table or lands visibly tilted.
- Require players to state the attacking territory, defending territory, and number of dice before rolling.
- Keep alliances informal and temporary; players remain free to change plans on their own turns.
- Use fixed-round scoring when the available playing time is limited.
