Roll This™Roll an attack
Tap d20, tap + on the modifier until it shows your attack bonus, then tap Roll. Or tap 123 and type it, like 1d20 + 5.
A natural 20 or a natural 1 shows under the total, so you can tell a critical hit or a sure miss at a glance.
A free 5e dice roller
Roll This is a dice roller for fifth edition games, made for phones. Tap the dice or type a roll like 1d20 + 5. It's free, with no ads or accounts, and once it's open it works offline.
Advantage and disadvantage
Pick Adv, and a d20 roll rolls two d20s and keeps the higher. Dis keeps the lower. Both dice show, with the one that doesn't count crossed out, and your pick stays until you choose Normal again.
Only the d20 changes. Damage dice roll as usual with Adv or Dis on.
Damage and critical hits
Build damage the same way: tap d8 and set the modifier to +3 for a longsword's 1d8 + 3. Each die shows what it rolled, and the total adds them up.
On a critical hit, the rules roll the attack's damage dice twice, so tap d8 twice for 2d8 + 3. The modifier is still added only once.
Everything else at the table
- Checks and saving throws. A d20 plus your bonus, with Adv or Dis when the GM calls for it.
- Big piles of dice. Tap d6 eight times for 8d6, or type it.
- Percentile and coins. A d100 for random tables, and a coin flip.
- Copy a result. The button in the corner copies it, ready to paste into a chat.
- Ability scores. The Stat Roller in the menu rolls a new character's six scores. See how it works.
When you want more
Roll This+ adds character sheets that roll your attacks, checks and spells with the right bonus, offer Roll Crit Damage after a natural 20, and keep your last 60 rolls. See what's in Roll This+.
