Chinchiller Diceis a bluffing game of literal blind trust.
When it is your turn, you roll the two dice, trying to score as much sand from the general supply as possible. You may re-roll any die that has not landed special side up as often as you like. Sooner or later though you will roll two chinchillers and have to close an eye.
Once both your eyes are closed, you can not re-roll any dice any more when it is your turn again. Instead, your left neighbor will tell you what you have rolled after just one roll. Your neighbor will also be the one who will have to pay for any sand you are scoring while blind. As a result, there is a good chance your neighbor will try to cheat you. It will be up to you to either accept your neighbor's word blindly or to try to catch them in the act. However, if you are greedy while your neighbor is telling the truth, you will be the one losing precious sand.
