Roll To Defend Calculators
Use these tools to compare roll odds, luck boosts, DPS, upgrades, zones, and offline income without pretending unverified values are final.
Pick the decision you are making
Live tools are ready to use now. Planned tools stay visible so you know where each progression question will fit as more data is checked.
Luck and Roll Odds
Estimate adjusted single-roll chance, expected rolls, hit chance, and miss chance.
DPS and Unit Slots
Plan team DPS, enemy HP targets, and slot value once your unit numbers are ready.
Upgrade Planner
Compare roll speed, luck, slots, zones, and income choices with user-entered costs.
Offline Income
Estimate idle earnings, roll budget, and progress toward the next upgrade.
How to read these results
If Roll to Defend later publishes official odds, unit stats, upgrade costs, or offline income caps, the calculators should use those values. Until then, enter the numbers you can see in your own session.
