The most entertaining Dapp I've used recently is @gacha_game_ on @Abstract. This meme token lottery project is quite addictive.
This dapp has onboarded a total of 90k accounts and sold 3.7M tickets to date. However, daa is around 1k and new user onboarding is around 50, which isn't an exceptionally high number.
Nevertheless, the retention rate is very high, and an interesting metric is that the average tickets purchased per person appears to be trending upward quite nicely.
If there's a true fanbase, that product always has the potential to succeed. I can see quite a few similarly interesting protocols on Abstract๐
