still wonder if a doubler dice (DD) could work in duel or tdm.
the DD as used in backgammon is usually used to fasten games up, like player A has 80% win chance, uses DD -> player B rejects, and the next game starts, similar to forfeit in ql

but theres a lot more to it. it is also used to put pressure on the enemy. some examples:
- match best of 7. player A leads 4-1. in the 5th game he gets a bit luck in the beginning and has a winchance of 60%. now he uses DD. player B is now in deep shit. if he rejects, he only loses 1 point, but 40% win chance is pretty OKish @ beginning of a game.
- match bo 7. player A leads 6-1. when the 8th game starts, player B starts with 1 good roll and uses DD (although only having 51% win chance). player A will probably reject this, player B wins 1 match.
- match bo7. Player B has already lost it, uses DD for the
a.s.o.

this is, how a DD could work in ql.
- when a Player clicks on DD, the game pauses
- if the other player rejects it, he loses the game
- If a player takes a DD, some stuff happening:
- all major PUs disappear
- the PUs will be activated and back in game, when the Player with DD walks over the spot (f.e. gets 100 health, and mh is back in the game and will spawn in 35 sec)

means, Player who takes DD has +200 free ups, and also the timing. so its a big advantage to make a comeback
