https://tangledice.com is the first provable fair dice gambling site for IOTA.
Users of IOTA act as both: miners and validators. The more transactions that are attached to the network, the faster other transactions get confirmed ! With other words, by playing dice, we enhance the tangle network. More importantly, you can play dice without paying fees !
Moreover, we've built a backend that automatically promotes/reattaches incoming and outgoing transactions in the background on our server. You can find all transactions that our promotor did after the snapshot here:
