There have been nearly 730 MILLION bets on Bustabit [as of October 26th, 2019]. Over a 50 game sample, you are bound to find some crazy anomalies - some that benefit the player, some that benefit the house. I took a screenshot recently of an 11 game streak of 3.00x+ crashes on Bustabit. Despite the odds of this occurring hovering around ~0.0002%, nobody claimed the site was rigged then.
