Run TRPG checks in two taps
- Add a label and numbers. Name the check (for example Attack or Perception), choose d20 or d100, set your modifier and an optional DC.
- Choose roll over or roll under. Use the checkbox to switch between “total ≥ DC” and “total ≤ DC” style checks.
- Roll and share with your table. Tap Roll to see the total and outcome, then copy text, PNG, or a prefilled URL for chat or overlays.
- Set XdY+Z. Choose N dice, S sides, and an optional modifier Z (for example 8d6+3 for damage).
- Roll once for a quick total. Tap Roll to see the total and a compact list of individual dice.
- Share totals for combat and stats. Use the result for damage rolls, HP or ability generation, and copy it as text or PNG.
- Choose N and S. For example, 10 dice with 10 sides for a 10d10 pool.
- Set the success threshold. If 8+ counts as a success, set T to 8.
- Read and share successes. Check the total successes and a compact roll summary, then share as text or PNG.

At-the-table workflow
Pick the roll mode first
Use Check for d20 or d100 style pass/fail rolls, Sum for damage or stat rolls such as 8d6+3, and Pool when you need to count how many dice meet a threshold.
Set only the values your table cares about
For checks, focus on the DC, modifier, and advantage style. For pools, focus on the threshold and whether sorted rolls make the output easier to read in chat or on stream.
Share the result in the format your group needs
Copy text is fastest for chat logs, Copy PNG is best for visual overlays, and Copy link gives another player the same setup without exposing any server-side history.
Keep rolls readable
- Add a short label such as Attack, Perception, or Fireball damage.
- Use the history list to confirm what was rolled before you copy it.
- Switch modes instead of overloading one roll type with house-rule workarounds.
How to use & FAQ
Keep everything local, read totals at a glance, and share clean logs as text, PNG, or URL while playing or streaming.
What can I do with this TRPG dice check tool?
You can run d20 checks with advantage or disadvantage, compare totals against a DC, and roll dice pools that count how many results meet a success threshold. Everything runs in your browser, with optional labels and a local history for logging your sessions.
How can I share my rolls with my group?
Use Copy text for chat logs, Copy PNG or Download PNG for visual cards, and Copy URL to share a prefilled link with the same inputs. Everything runs in your browser, and neither your inputs nor rolls are uploaded to a server.
What is the difference between Check, Sum, and Pool?
Check is for one success/fail roll against a DC, Sum adds multiple dice plus an optional modifier, and Pool counts how many dice meet a success threshold. Switching modes changes both the form and the way the result is summarized.
Are my rolls uploaded or stored on a server?
No. Rolls, labels, and history stay in your browser. Sharing only happens when you copy text, copy a PNG, or send the prefilled URL yourself.
