>Start with decimal odds if you can, because they are the easiest to sanity-check: stake times odds equals total return, so you can see the payout before worrying about other formats. The biggest trap is carrying over casino thinking into sports, because pages like
https://livedealerindia.com/games/shows/,
https://moneytimegame.org/, and
https://vortexgame.org/ are still in the casino/game-show world, while sports lines move because of matchup info, injuries, time left, and market action. I would definately avoid parlays at first and just follow simple moneyline bets until you understand why a favorite pays less than an underdog. Also, live odds can look tempting, but they change fast, so pre-match lines are usually better for learning.
