Are the rolls actually fair?

Yes, everywhere in this family. Every face is drawn from the browser's cryptographic random number generator with rejection sampling, so each face is exactly one in six rather than nearly one in six, and the same is true of a d20 or a d100. Where there is an animation, the faces are drawn before anything moves and the tumble is a replay of a result that was already decided.

How many dice can I roll?

Up to two on the plain roller, up to six down the tower or under the cup, and up to twenty in the pool, which also does d4 to d100, modifiers, success counts, keep highest or lowest, exploding and reroll ones. Pick the page by what the roll needs rather than by how many dice it has.

Yes. Up to ten boards, in this browser, along with their terrain and their tokens. The fog of war page can load the same saved boards, so a board painted once can be run twice, and either page can hand you a PNG of the board to keep.

Can I write my own tables?

Every table here is editable and yours are saved on the device. The dungeon rooms, the encounter table and the map all ship with tables you can play from straight away and replace a line at a time.

Does it work on a phone at the table?

That is what it is for. The dice go full screen so the faces read across a board, and the boards scroll inside their own box with cells big enough to tap, so a wide board never turns the page sideways.

When the dice are missing

A board game box loses its dice faster than it loses anything else. They go under the sofa, into another box, or into the hands of the smallest person in the house and are not seen again. Everything else in the box is fine, and the game is unplayable, which is an annoying way for an evening to end.

A roller on the screen fixes that in about two seconds, and it fixes a second thing as well: nobody can accuse the dice of being cocked, of having fallen off the table, or of having been scooped up before the room saw them. The face is drawn before the tumble animates, so the roll you watch is a replay of the result rather than an attempt to produce one.

Four ways to roll

The dice roller is one or two six-sided dice and a total, which covers most family board games. The dice tower is the same roll with the clatter: dice go in the top, hit three rows of baffles and land in a tray nobody can reach into. The dice cup hides the roll instead, for the bluffing games where what you know and what you say are different things.

The dice pool is the one for role-playing: any mix from d4 to d100, modifiers, successes counted against a target, keep the highest three of four, exploding sixes and rerolled ones, typed as notation or tapped together. It reads the pool back in plain words so the table can hear what is about to be rolled.

Boards, and what is on them

The hex board paints terrain on a hex or square grid, takes a token per player, measures between two cells and saves the result. Fog of war loads the same boards and puts two views on one screen: the host sees everything, the players see what they have uncovered, and the host view sits behind a hold so nobody can glance at it.

Explore the map is the version where the board is not painted in advance: face-down tiles that turn over into a location and an event drawn from your own tables, spreading outwards from wherever you started.

Rooms, encounters and the thing in the last room

Dungeon rooms draws a room, a feature, an occupant and a number of exits together and keeps a list that reads back like a map of where you have been. The encounter table is the general case: rows of a dice range and a result, rolled or drawn, with one table able to send you to another.

The boss tracker is for the fight at the end. A health bar the room can read, phase thresholds, and the rules for the current phase on the screen so the change is announced by the tool rather than remembered by one person. For an ordinary fight, the health bar is the simpler page.

Nothing is uploaded

Your boards, your tables, your recipes for a roll and your boss all live in the browser on the device in front of you. There is no account, no room to join and no server to send any of it to, which is also why the device you set a campaign up on is the device you have to run it from.

A share link carries settings and nothing else: how many dice, the notation for a pool, the shape and size of a board. Nothing anybody typed travels in a link, so a table you spent an evening writing stays where you wrote it.
