OP, you don't have to blame yourself for your loss; the reality is that you have just lost the game, and that's what gambling is all about. Either you win or you lose. But if I were you, I would probably have staked the game twice; the first one will be for your original stake, and for the second one, you will just have to reduce the odds either by removing the last games you added, or if you still have doubts on the two stakes, you might want to make it three by reducing the odds again and stake the remaining ones. For example, if you place a bet on 15 sports games for #1.7k, you can repeat the same bet, but you will just have to remove some games and stake on the rest. You can do it up to three places, so one of them will definitely 😁 give you a win.
There is one popular saying among gamblers in my local area: "Game way go cut go cut." Even if the OP has the idea of interchanging the game into three different places just to make sure that something will be won at the end of the day, something will definitely still make him add some more odd to make them round again, even if it's the lowest amount from the already staked one. Especially in the kind of game that the OP used "Visual Game" before, you can rearrange your game into three different places. The game might have even ended already. They are not like normal football sport betting; the games just happen some fast. I haven't tried it before, but I know it doesn't take up to 30 minutes before each game starts and ends.
