I think I'll go for parlays, although I know very much that straight bets increased the chances of winning since it's only individual bets, but the financial implication can lead someone to easy addiction from chasing lost capital for recovery if you lose, but I'm parlays, you can try out your luck several times and not even spend as much money as possible when you use straight bets.
You have more betting options and a lower probability of winning; you should bet correctly on all your bets to get a good win.
I once placed a random multiple bet with $3 and took home about $450. I know I had a good dose of luck, but by playing games considered low-odd and therefore with high odds, I got this.
Unfortunately, this isn't always the case.
