Your bonus scenario

Hypothetical example

Educational example · No casino selected

A $100 deposit, 100% match capped at $100, 10× bonus-only wagering and 20% blackjack contribution.

Adjust offer terms and assumptions

Headline multipliers are divided by the blackjack contribution rate.

Scenario calculation

This arithmetic does not predict whether you will finish wagering, your chance of ruin, or your final withdrawable balance. Estimated cost assumes all modeled wagers are completed at the chosen house edge. Variance, sticky bonuses, cashout caps, expiry and excluded play can change the outcome.

What the numbers mean

Understand our sources and calculator assumptions →

Bonus awarded

The deposit multiplied by the match percentage, limited by the maximum bonus. A total advertised across several deposits is not the cap on your first deposit.

Actual blackjack stakes

For a headline requirement, divide qualifying wagering by the eligible game contribution. A 20% rate requires five dollars in eligible stakes for one dollar of credit. At 0%, blackjack cannot complete a positive requirement.

Estimated wagering cost

Total modeled stakes multiplied by the assumed house edge. This is a simplified average-cost illustration, not a net-profit calculation. A balance can run out before the wagering target is reached.

Read the right multiplier

LCB’s blackjack-specific multipliers already account for the game. The presets explicitly label these figures and lock contribution at 100% to avoid dividing twice. Where operator rules conflict with a listing, the calculation is labelled conditional; the source notes retain that conflict. Editing a preset creates your own scenario.

Before using an offer

Confirm your location, exact coupon and eligible blackjack title, minimum deposit, maximum total bet, contribution, deadline, sticky-bonus treatment and cashout cap. Free spins, chip face value and separate no-deposit offers are excluded from deposit-match calculations. UK offers use GBP; Jackpotter uses USDT; other examples use USD. Slots rewards and live chips have separate summaries. UK offers are not U.S. offers; Liberty Slots and Lincoln block the U.S., UK and Canada. No currency conversion is performed.
