What is Risk?
Risk is a territory-control board game where combat repeatedly asks a very small question: which side loses armies in this comparison? The attacker and defender do not add their dice. They sort them and compare the highest available pairs. Keeping those groups distinct is the main job of this page. The overall campaign, reinforcements and territorial decisions still happen on the actual board.
How to use the presets
The battle presets use one to three attacker dice and one or two defender dice. The results are sorted within each group, paired from highest down and compared; tied pairs favor the defender. The tool reports losses for this comparison only. It does not check whether enough armies are present to permit your chosen dice count, and it does not continue rolling an entire invasion automatically.
Attacker 6, 4, 1 versus defender 5, 4 produces one loss for each side: six wins the first pair, the tied fours favor defense.
Practical table tips
- Choose legal pool sizes from the board before rolling. A tray containing three attacker dice is not evidence that the attacking territory has enough armies.
- Resolve one battle comparison, update the board, then decide whether to attack again. Do not treat a previous three-die choice as permanently valid.
- Use the group labels in the shared text to keep attacker and defender unmistakable. Swapping them changes the meaning of ties.
Risk dice FAQ
Does the defender win tied dice?
Yes, for the classic comparison implemented here.
Does it simulate a whole battle?
No. Each press resolves only the current dice comparison; casualties and the next attack remain your decisions.
Can I add modifiers?
Arithmetic modifiers are ignored in this comparison mode. Special editions should be resolved under their own rules.
This is the classic comparison, not an implementation of every Risk edition or campaign rule.
