About this page
The d6 is the cube from board games and classroom probability. This page starts at one die with six faces. Each roll draws 1, 2, 3, 4, 5, or 6 with equal probability. The average of a fair d6 is 3.5, which is why a long game of adding one die drifts toward the middle even though 3.5 is not itself a face. If you set the count to two, you are rolling 2d6: thirty-six ordered pairs, not eleven equally likely sums. For a page that talks through that sum, open the 2d6 roller. For a naked integer with no die chrome, open the 1–6 number range. Nothing is rolled when you arrive.

Questions
Is this a standard six-sided die?
Yes. Faces run from 1 through 6, one draw each. It is not a d6 that includes 0. If your house rule blanks a face, decide what blank means before you roll and apply it yourself. The roller will not invent a blank.
What is the chance of a 6?
1 in 6 on a single die. Two sixes in a row on one die, rolled twice, is 1 in 36. Each roll is chosen when you press the button. Animation only reveals that draw. The browser uses crypto.getRandomValues and rejection sampling, which the methodology page spells out. This is not a loaded die, and it is not atmospheric noise. The history list does not spend the six. The next roll is allowed to be a six again.
What is the average roll?
The expected value is (1+2+3+4+5+6) / 6 = 3.5. You will never roll a 3.5. The average shows up across many rolls. In a short turn, 1 and 6 are normal. Teachers can have students tally thirty rolls and compare the tally with this even split. Thirty is still a small sample.
Can I use this in place of a physical die?
For a casual board game, yes, if everyone can see the screen and agrees the digital die replaces the cube. Competitive events may require physical dice or a specific app. ChanceKit is not an event authority. Copy the result if the scorepad needs it.
How do I roll two dice that I add together?
Set dice to 2 on this page, or open the 2d6 page, which starts there and explains why 7 is the common sum. Do not use the number generator from 2 to 12 if you want board-game movement. That range makes 2 and 12 as common as 7, and real 2d6 does not.
Are old rolls saved?
Only in the strip for this visit. There is no account. A reload clears the strip. If a dispute depends on the last roll, read it off the screen before anyone refreshes. The methodology page explains why the site does not keep a server log of your rolls.
How should a class tally a d6?
Roll at least thirty times, mark a column for each face, and compare the columns with an even split of about five each. The columns will not match. The lesson is the gap, not a hunt for a broken die. Keep the same face count the whole time. Switching to two dice midway mixes a uniform face with a summed distribution and the chart stops meaning anything. Copy is unnecessary if the tally is on the board and everyone watched the boxes.
