Plot
Nao Kanzaki, an honest college student, receives a 100 million yen one day, along with a card saying that she has been chosen to participate in the "Liar Game". In order to win the game, she must trick other players into giving her their 100 million yen while her opponents are left in debt.
The objective of the first round is to steal the 100 million yen that is issued to her opponent, Kazuo Fujisawa, a former
teacher of hers, who easily deceives her. Before the round ends, she comes across Shinichi Akiyama, a genius swindler, who helps her to succeed winning the first round. However, after the first round, a second round of Liar Game awaits them.

Ok this is my fav show of all times, i just wish it was longer b/c it is only 11 episodes, but the final episode is over 2 hours long xD. Also i wish that the manga would get English subbed.
Now the first game in the show in my opinion was kinda boring, the last 3 games were the best
