Mia is an ancient bluffing dice game using two dice and a cup to conceal the dice. Players take turns rolling the dice beneath a cup and announcing a higher roll than the previous roll. This announcement can be challenged. Also, players may pass their turn without viewing the roll under the cup to the next player. In this case the passer assumes responsibility for the roll as if they had rolled it.

One interesting feature of Mia is the non-standard ordering of rolls. 21 is 'Mia', the highest roll. Next come the doubles in ascending order: 11 is the second best roll, then 22, 33, 44, 55, 66. From there the numbers descend, with the higher die always naming the tens value and the lower die naming the ones value: 65, 64, ..., 32, and 31 as the lowest value.
