Is the tumble real, or is the result decided first?

Both, in that order. The faces are drawn with the browser's cryptographic random number generator before a single die moves, and the tower then runs a genuine physics simulation so you have something to watch. The dice that land in the tray show the faces that were already drawn. Nothing about the fall changes them, which is exactly how a real tower works too: the tower is there to stop a practised hand placing a die, not to decide anything.

Why use a tower at all instead of just rolling?

Because a tower is cheat proof and tidy. Dice that go in the top cannot be slid, spun or set, they cannot skitter off the table into somebody's drink, and they land in the same small tray every time. Groups that play on a crowded table or with a player who rolls with more enthusiasm than accuracy tend to end up with one.

Can I turn the clatter off?

Yes. The Sound tab has one switch and the page starts silent until you press it, because nothing on this site plays audio before you ask. With sound off the faces and the total are still written out on screen and announced to a screen reader the moment the dice settle.

How many dice can go in?

One to six, all of them six sided. Pick the count on the Dice tab and it is remembered on this device. If you need larger dice, a pool that keeps and rerolls some of them, or a count above six, the dice pool roller takes notation like 4d6kh3 and the plain dice roller is the simpler page again.

Does a share link give somebody my rolls?

No. A share link carries how many dice go in the top and nothing else. Your rolls and your history never leave this browser, because there is no account here and no server to send them to.

Dice tower

Drop up to six dice in the top, hear them clatter down the baffles, read them in the tray.

Drop to roll

How many dice

Every die is a six. The faces are drawn before the first die moves, so the tumble you watch is the one that matches them.

The last ten rolls

Nothing rolled yet.

What a tower is for

A dice tower is a box with baffles in it. Dice go in the top, hit the baffles on the way down and drop into a tray at the bottom. Nobody at the table can set a die, nudge one, or claim a roll that hopped off the edge of the board and landed under a chair. The tower takes the argument out of the roll, which is why heavy war games and long campaign nights tend to grow one.

The other reason is noise. A tower makes a satisfying racket, and a table that can hear a roll is a table that knows a roll happened. That is a small thing until somebody quietly rerolls, and then it is not.

For a plain roll with more dice and more sides, use the dice roller, and for pools with modifiers, successes and rerolls the dice pool takes the notation. For something that has to come out of a bag rather than a tower, the bag of tokens does draws without replacement, which dice cannot do.
