How free spins work, where to use them, and expiry rules
Big Boost Casino Bonuses
Big Boost Casino offers a welcome bonus on the first deposit: 100% match up to $300, with a $20 minimum deposit. The bonus carries a 35x wagering requirement, and the maximum bonus conversion is capped at $5,000. Bonus funds expire after 14 days, and game weighting applies (slots count 100%, table games 10%).
New players also get 100 free spins on selected slots (for example, 20 spins per day for 5 days) when the first deposit qualifies. Free-spin winnings are credited as bonus money with a 35x wagering requirement, and the maximum win from the free spins is capped at $200. Spins must be used within 24 hours after they are issued.
For ongoing promos, Big Boost runs a weekly cashback deal: 10% back on net losses from slots, credited every Monday, with a $10 minimum cashback and a $200 weekly cap. The casino also rotates short-term offers such as weekend reloads (50% up to $100 on deposits from $20, 30x wagering) and slot tournaments with fixed prize pools, where points come from real-money spins.
Summary: Big Boost focuses on a mid-sized first-deposit match, structured free spins, and a capped weekly cashback, with rotating reload promos between weekends.

What Promo Codes Are
A promo code in Big Boost is a short text code you enter to unlock a specific offer. The code can trigger a deposit bonus, free spins on a named slot, or a bet credit for sports. Each code has fixed conditions: an expiry date, an eligible product (casino or sports), and a minimum deposit if it’s tied to a payment.
Where To Find Them
Big Boost publishes promo codes in three places: the Promotions page inside your account, marketing emails, and push notifications in the mobile app. Some codes are partner-only and appear on affiliate pages, but they still follow the same rules once you enter them. If a code is valid, the promo text will state the game list (if any) and the wagering requirement in numbers.
How To Activate
Log in, open Cashier → Deposit, choose your payment method, and look for the Promo code field. Paste the code, press Apply, then deposit the exact amount required by the offer (for example, if the minimum is $20, a $19.99 deposit won’t qualify). Big Boost credits the bonus right after the deposit clears; free spins usually appear in the casino wallet and attach to the listed slots automatically.
For no-deposit codes, go to Promotions → Redeem code, enter the code, and confirm. Check Bonus or My rewards to see the balance type (cash, bonus funds, free spins) and the deadline. If you start playing before the bonus is credited, the first bets can come from cash balance, so confirm the bonus is active before you place wagers.

Wagering (Playthrough) In Big Boost: What It Means
In Big Boost, a wagering requirement is the total amount you must bet after taking a bonus before you can withdraw any winnings linked to that bonus. The calculation is simple: bonus amount × wagering multiplier = required bets, and Big Boost counts settled bets only (voided or cancelled bets do not count).
- Example 1 (100% match, 35x): You deposit $50 and Big Boost gives a $50 bonus with 35x wagering on the bonus. Your playthrough target is $50 × 35 = $1,750 in total bets. If you place $5 spins, you need 350 settled $5 spins to finish the requirement.
- Example 2 (Free spins, 40x on winnings): You receive free spins and win $30. Big Boost applies 40x wagering to the free spin winnings, so you must place $30 × 40 = $1,200 in total bets before those winnings become withdrawable.
