I am pretty sure that there will be many gamblers who will try their luck to this kind of game especially that the reward is pretty high which is 16 times to their bet if they can guess correctly the last digit of their block has transaction.
But the choices is 16 so the percentage to guess correctly the last digit is a little bit small but not that small compare to lotto and other jackpots. I would be love to try my luck to this one.
In fact, not many players love to play this game. See, it is a 4 years old site but not many activities in this thread as well as on the site.
Now they have just changed the game into LTC only, probably due to the high tx fee of bitcoin which makes them get less players compared when the tx fee is of btc is in normal condition.
Frankly speaking the game is not really attractive for these days, I myself prefer to bet on dice game with 16x payout instead of playing this kind of game.
For sure, it is a matter of taste. Every single person has their own preferences which game to play, so good luck if you are going to play this game.
