I thought Monopoly only used a single six-sided die, why are they rolling two of them?

[kgermino]

Because your understanding is wrong. The game uses 2 dice.

You can't roll doubles to get another roll with a single die

[snypher]

You could roll it twice and compare the two results.

[dylan604]

You're second roll "trying" for doubles just meant you took a second turn, so you've sort of turned it into bowling style scoring. Pick up the spare, and get another roll.
