Just watched the first ep for this spring season anime. This has some vibrant colors and a story line liken to the Hong Kong movie series, God of Gamblers. A lot of plays and cheats to out smart the opponent is the main parallel I see with this series.

This looks like a promising series.
God of Gamblers, that brings back some good memories of HK films. I'm liking NGNL quite a bit.
