Lelouch can lose, The Blank haven't lossed (yet) but Shiro (no game no life) can think extra-ordinarily fast and think of multiple possibilities... PLUS They bet a God anyway soooo there's pretty much no chance Lelouch could win.
P.S. No Game No life is better than Code Geass
Tell me about it, an epaulette mate was given to a god
