My Review will be in 5 Main Parts:
1- The Goal (10 out of 10):
The Anime have several goals like "Never give up, Think Then decide, Fulfillment, Teamwork, ..... etc" And all of those goals positive and the anime delivered it to the viewer in a clear way.
The main goal is That "Gambling is Bad", It is obviously that the anime all about gambling and how it's risky and that the hard work is the way to what you want because that gambling is for lazy men who will end up dead, bankrupt or indebted and the lucky one will be rich, but it's a lust in the end so he will continue Gambling and fall in the same problem (it is a cycle that not end).
2- The Excitement: (10 out of 10)
It found here in hard situations when kaiji make a decision, And that was done very good and make me feel that Difficulty.
3- The influence: (8 out of 10)
The anime make me interact with every scene of win, lose, sadness, happiness *BUT* the sad scenes was less influence that not made me full interact.
4- The Vital (7 out of 10)
The anime make me watch it in 4 days only -season 1 in 3 days and season 2 in two days- Every new episode take me to the next one *BUT* season 2 made me bored in some episodes where i think There was unnecessary lengthening.
5- Overview (7 out of 10)
As general it was very good anime *BUT* these are some of the points where the anime did not succeed in my view:
1- The scenes of full nudity of the characters in the room of losers it wasn't should to be like this, They could have been partially naked until they go to the permanent punishment, specially that some of them went out from the room.
2- The girl that didn't showed in the anime but mentioned only, why her picture in bikini showed every episode in season 2? "the episode end was enough for her story with kaiji".
My Rating: 42/50 == 8/10
