15 losses within 100 bets is uncommon. But you can't address the game as rigged by placing just 100 to 1k bets, the house edge can be judged by placing a few thousand bets. The house edge system is a bit different on BitKong. Were you playing in the bonus mode house edge or normal house edge?

The house edge of the limbo game is 5% in the 'bonus boost' mode. For the dice game, the house edge is almost 8% in the bonus boost mode.
