Buyback

Any won item can be sold back at 85% of its stated value, set by the contract constant BUYBACK_BPS = 8500 rather than quoted per sale. A sell-back credits the seller's withdrawable balance, and the 15% spread returns to the bankroll.

The 95% figure is the return with items kept and credit counted at face value. Only the item portion can be sold back: it is 48.33% of stake, and at 85% it realises 41.08% in cash. Selling every won item leaves total return at 87.75% with credit still counted at face, or 41.08% counting cash alone.

An item can be redeemed physically, held, or sold back for withdrawable USDG.

Draw credit

Draw credit is a separate balance from the withdrawable one. It is paid by the credit tier, spends only on further draws, and is applied before cash on every draw, so it cannot be converted to USDG by any route.

At 70% of draws paying 100 credit against a 150 stake, credit funds two thirds of a subsequent draw, which itself returns 95%. Credit therefore compounds downward rather than converting out, and is the reason the cash-equivalent return is 48.33% against a headline 95.00%.

withdraw() takes no arguments and pays the caller their own credited balance. It does not pay draw credit.
