Funfair (FUN) is a really promising token with some groundbreaking state channels that will allow for provably fair gambling while merging several rolls into a single ethereum transaction.
I also like Kyber network as they will introduce decentralized markets with extra features like derivatives and options trading.
FUN does seem to be an interesting project, probably the most "serious" one in the gambling section of cryptocurrencies. I'm definitely taking a closer look at it whenever i rebalance my portfolio in the upcoming month, for holding through 2018.
