I have no problem in it, but there has to be a single amount (no double entries - can't account for 2 entries in a single roll) and the amount is fixed (e.g. 50g). This will ensure that someone isn't going to put in 1g to the lotto and get 1k in return

.
The Lottery is an excellent idea to aid in building the vault, especially for those that are using it for repairs and never putting a dime (or copper even) back in (yes, the ociffers are watching)!!
