Short answer. Duelbits does not match deposits. Its casino welcome offer, Rookie Rush, pays free spins scaled to the first deposit: $20 activates the offer, $50 gives 25 spins, $250 gives 125 and $500 gives 250, on selected Pragmatic Play slots. The sportsbook offer is a free bet equal to the first deposit up to $100, released after you wager the deposit five times across at least four bet slips at odds of 1.50 or higher; free-bet winnings are paid as cash. Rakeback through "Ace's VIP Lounge" starts at 5% and rises to 12.5% with no wagering requirement. No promo code is needed for any of these.

What is missing from the public page
The promotion page does not state whether Rookie Rush spin winnings carry a wagering requirement, how long the spins stay valid, or the spin value. Third-party reviews claim "no wagering" and either 24 hours or 7 days; we could not confirm either and the calculator leaves these fields for you to fill from your account. We will update this page when Duelbits publishes the figures.
How the offers compare
A $100 deposit at Duelbits buys 25 free spins plus rakeback, with no requirement attached to the deposit itself. The same $100 at a 40× bonus-only casino buys a $100 bonus that costs about $160 in expected losses to clear. For most players the Duelbits structure is cheaper, because nothing locks the deposit; the price is that the upside is small. The sports free bet does lock the deposit until it is wagered 5× at minimum odds, which at a typical 5% margin per slip costs about $25 of expected loss on a $100 deposit, against a $100 free bet whose cash value depends on the odds you choose.
