Resolve one tense roll when everyone wants to see the dice.
Risk battle calculator
Resolve Risk battles without slowing the table.
When a fight gets repetitive, Risk Calculator handles the dice math and troop losses so players can keep arguing about strategy instead of counting rolls.
Let the app finish a large attack when the outcome is mostly bookkeeping.
Show remaining attacking and defending troops after each result.

Useful when the board gets crowded
Long troop exchanges can pull attention away from the map. A dedicated calculator keeps the flow moving while the board state stays visible.
