Share my experience playing ball.

When I place bets, it’s basically a set of combinations.
Win/Draw/Lose, Over/Under, match score, live betting, and upset-score combinations are all combined.
The biggest advantage of this set is that if the regular selections hit, it’s basically small wins and small losses, so you won’t suffer a big loss—but if an upset hits, it’s a big win!
So my basic thinking and strategy is: use combinations to bet on upsets for big wins!
Also, it’s about finding patterns. This World Cup has seen more high-scoring games; especially in the second round, I bet on Over in every match and won quite a bit.
The principle is simple: in the group stage, teams’ strengths vary a lot, making high-scoring games more likely. And in the second round, no matter how strong or weak the teams are, nobody can just slack off—they have to fight for victory with full effort. Plus, this World Cup was changed to a four-quarter format with extra-long stoppage time, which also makes high-scoring games more likely.
Small bets are just for fun!
The above isn’t teaching anyone to gamble—just offering an idea for reference.
