When I play multiply BTC, I take the bonus, and it showing wager remaining before I can officially "cash out" the BTC.

Regarding the wager remaining, let say:-

1. 1st roll, bet 100 satoshi, wager remaining deduct 100 satoshi (Loss)
2. 2nd roll, bet 200 satoshi, wager remaining shall deduct 200 satoshi right? I noticed that it deduct less than 200 satoshi.

If 2nd roll loss and I continue to double my bet, the wager remaining deducted is much much lesser than my bet.

Any Sifu mind to share how the wager remaining deducted based on bet?

Thanks.
