This is a simple Liar's Dice roll generator, to allow a group of people to play the game
online without having to carry dozens of physical dice, or install a phone app.
Basic rules: Each player privately loads this page on their phone or computer
and positions the device so that no other player can see the screen.
The starting player announces the minimum number of instances of a particular number
they think appear in total across all players' dice
(eg. "seven 3s"). 1s are wild, and always count as the predicted number.
Going clockwise, each player may either raise the previous player's bid
(either to a higher quantity of the same number, or any quantity of a higher
number) or challenge it. When a challenge is made, everyone reveals their screens; if
the challenged prediction was correct (ie. at least that many instances of the number
are present, including wild 1s), the predicter wins, otherwise the
challenger wins. The loser of the challenge loses one die and they open the
next round; when a player runs out of dice, they're eliminated.
A variant: You can drop the bid number back to 1 if you halve the quantity before increasing it
(eg. you can follow "seven 3s" with "four 1s"), but having done so play can only
return to other numbers by doubling the quantity before increasing (eg. "four 1s" to "nine 4s").
(The background baize cycles through six colours when reloaded,
starting from green; if you're concerned about illegal rerolling, synchronise
your colours at the start. And you can give everyone the shorter URL kevan.org/ld to
