Free Tabletop Battle Simulator
Tabletop Battle Simulator helps tabletop RPG, DnD-style, skirmish, and wargame players test attack plans before a fight. Enter attacker count, hit chance, damage dice, crit rule, defense value, armor reduction, hit points, and round limit to see damage, kill odds, survival odds, expected rounds, and tactic changes.
Built for pre-combat planning, encounter tuning, resource checks, and quick risk reads without claiming any official game rules.
Start Tabletop Battle Simulator here: set your attack pool, defense, armor, health, crit behavior, and round budget, then compare damage, kill chance, survival chance, and tactic win rate instantly.
Enter the attack plan and defender stats. Damage dice support formats like 1d8+3, 2d6, or 3d4+1.

Tabletop Battle Simulator is a generic probability model. It approximates damage distributions from dice notation, defense-adjusted hit chance, armor reduction per hit, and simple tactical risk modifiers.
Tabletop Battle Simulator turns attack pools, dice, defense, armor, hit points, and rounds into practical combat odds.
Enter attacker count, hit rate, damage dice, critical behavior, defense, armor reduction, target hit points, and round limit to model a full attack plan.
Compare aggressive, balanced, and defensive tactics to see how win chance changes when damage, accuracy, and survival risk move together.
Use this Tabletop Battle Simulator guide to turn a combat idea into a readable risk estimate before the encounter starts.
Enter how many attackers act each round, their expected hit rate, and a damage dice expression such as 1d8+3 or 2d6.
Add target defense, armor reduction, hit points, critical rule, and the number of rounds you are willing to spend.
Compare average damage, kill probability, survival probability, expected rounds, and the aggressive, balanced, and defensive win rates.
If kill chance is high but survival is low, the fight may be resource-expensive even when the attack plan works.
