Thank you for sharing this because now I learned something. I have been asking myself where to find the odds for games that have been played. I assume this is only for the pre-game odds, but you can't look up odds for like halftime when team 1 was down 0-2 and they won it 3-2 and you would like to know what the odds were at that point?
It takes some time, but I think more gamblers should test their own ideas with odds from the past and see how far they would have made it with their "incredibly smart considerations".
I learned it the hard way, I have tried these multi bets a couple of times and combined all the major favourite teams, but I can't actually tell you if it ever worked out when I went for these fun multi bets with perhaps 7+ games. I think it didn't.
Anything over 2-3 matches in one bet greatly reduces your chances of winning, so it is not surprising that with such bets the winnings are much smaller. I have tried to make big multi bets several times, but I have never managed to win, so I do not really like this idea. I would rather make several single bets and if one or two events lose, it will not ruin everything for me, but will only take away part of my money on losses. And if I am lucky enough to win all bets, then this will also be good, albeit with smaller winnings.
