D4 dice roller
A four-sided tetrahedral die, often used for small damage values, healing amounts and compact tabletop rules.
How this die works
A D4 has four triangular faces and produces a whole number from 1 to 4. Its shape is a tetrahedron, so the number shown at the top or bottom depends on the die design. Check the printed convention on a physical die; this digital roller displays the selected result directly.
When to use it
Use a D4 when a tabletop rule calls for 1d4, such as a small weapon die, a minor healing roll or a short random range.
A fair digital roll gives each face an equal chance. This roller uses the browser's secure random number generator where available.
