but the Roobet crash is only game I have managed to catch 7000x once.
It is so lucky of you. It is very seldom to catch that high multiplier unless you set your rolls in auto hoping to catch a random very high multiplier result. I wonder how much you wagered on that one and how long it is for you to catch such a high reward. I had been playing crash for so long and the most winnings I got is only 1000 multiplier.
