So, basically you're offering blind betting, where you decide how much you want to bet, but don't get to know the odds until after the bet is placed? I have to admit it's innovative...
Of course not - you are seeing the odds live. You send the bet and within 6-8 seconds your bet gets filled at the market price, which sometimes may deviate insignificantly from the price you saw - positively or negatively.
If we cannot lock the price you saw when you sent the bet, your bet will be returned - happens if a goal is scored or a red card given, as is usual with all live betting sites.
90% of the times we lock the price we show you. The other 10% it may deviate - especially if you bet around the end of the game when odds move wildly.
