Dice, Checks, and Saving Throws: A Beginner’s Guide
D&D looks complicated until you learn the simple pattern:
Roll a d20 + add a number + compare to a target.
The d20 and modifiers
Most of the time you roll a d20. The number you add is called a modifier, and it comes from an ability score or a skill.
Example: If you are good at Athletics, you might add +3 to climb a wall.
Ability checks
Use an ability check when a character tries something risky or uncertain, like sneaking past guards or persuading a shopkeeper.
- The Dungeon Master (DM) sets a Difficulty Class (DC).
- If your roll + modifier is equal to or higher than the DC, you succeed.
Saving throws
Saving throws happen when something bad is happening to you, like a trap or a spell. The rules are the same as a check, but the DM asks for a saving throw instead.
Advantage and disadvantage
If you have advantage, roll two d20s and take the higher one. If you have disadvantage, roll two d20s and take the lower one.
This keeps the game fast and adds excitement without extra math.

A simple example
You try to leap across a gap.
- The DM sets the DC at 12.
- You roll a 9 and add +4 Athletics.
- 9 + 4 = 13. You make the jump.
Remember this
When you feel stuck, just ask: What am I rolling? What am I adding? The rest falls into place quickly.
