The closest match to a $300 deposit bonus
A $300 deposit bonus is not among the current promotions. If you want to deposit $300, though, the 400% first deposit offer is the main match-style option. It requires a minimum deposit of $25 and adds a bonus equal to four times your deposit, plus 400 free spins.
For a $300 deposit, a 400% match would produce a $1,200 bonus. That gives you a combined deposit-and-bonus balance of $1,500 before wagering. The offer has 40× wagering on the combined deposit and bonus amount, so the calculation would be $1,500 × 40 = $60,000 in wagering.
A $10 maximum bet applies during bonus play
The first deposit bonus has a maximum bet of $10 while bonus funds are active. Keep that cap in mind even when making a larger deposit, and check that your play stays within the offer rules.
| Item | Calculation | Result |
|---|---|---|
| Deposit | Your chosen amount | $300 |
| Bonus | $300 × 400% | $1,200 |
| Combined amount | $300 + $1,200 | $1,500 |
| Wagering target | $1,500 × 40 | $60,000 |
The first deposit bonus: 400% plus 400 free spins
The headline welcome package combines a 400% deposit match with 400 free spins. You need to deposit at least $25, and the offer is available once per player. The 40× wagering requirement applies to the deposit and bonus together, rather than to the bonus alone.
Slots, blackjack, video poker and keno count towards wagering for this offer. The free spins are included with the first deposit package. The available information does not attach a separate cash value or named game list to those spins, so treat them as part of the package rather than adding an assumed dollar amount to the wagering calculation.
How to claim it
- Register an account
Enter your name, date of birth and email address. You must be at least 18 years old to register and play.
- Choose the first deposit offer
Select the 400% match with 400 free spins before completing your first deposit.
- Deposit at least $25
Enter your deposit amount in USD, AUD or EUR and complete the payment.
- Play within the terms
Use eligible games, keep each bonus-play bet at or below $10 and work through the 40× requirement on the combined amount.
Do the wagering maths first
The bigger the deposit, the bigger the matched balance and the larger the wagering target. A quick calculation before you claim can help you decide whether the offer suits your budget.
The no-rule first deposit option uses only 1× wagering
If 40× wagering feels too heavy, the no-rule first deposit option takes a different approach. It provides a 111% match on a minimum deposit of $25, with 1× wagering on the deposit and bonus combined. It is available on your first deposit.
For example, a $300 deposit would receive a $333 bonus at 111%. Your combined amount would be $633, making the wagering calculation $633 × 1 = $633. That is a much smaller target than the main 400% offer, although it does not include the 400 free spins.
| Item | Calculation | Result |
|---|---|---|
| Deposit | Your chosen amount | $300 |
| Bonus | $300 × 111% | $333 |
| Combined amount | $300 + $333 | $633 |
| Wagering target | $633 × 1 | $633 |
This option is useful for players who prefer a lower wagering multiplier over a larger headline match. Compare the actual bonus amount and the play requirement, rather than judging an offer by its percentage alone.
First deposit cashback gives you another way to start
The first deposit cashback offer returns 100% on deposits from $10. It has 30× wagering and a maximum cashout of five times the bonus amount. This is another first-deposit choice, so it should be considered alongside the match offers rather than stacked with them.
On a $300 deposit, a 100% cashback amount would be $300. The 30× wagering calculation would therefore be $300 × 30 = $9,000. The maximum cashout is five times the bonus amount, which would be $1,500 in this example.
| Term | Calculation | Result |
|---|---|---|
| Cashback | $300 × 100% | $300 |
| Wagering | $300 × 30 | $9,000 |
| Maximum cashout | $300 × 5 | $1,500 |
The cashback offer also has a $10 maximum bet during bonus play. It is available once after the first deposit, and the minimum qualifying deposit is $10.
The $100 free chip is the no-deposit alternative
You do not need to deposit to claim the $100 free chip. Sign up and use the code 100GO. The offer is available once per player, carries 30× wagering and has a maximum cashout of $100.
The wagering figure is based on the $100 chip, so the simple calculation is $100 × 30 = $3,000. The $100 cashout cap is separate from the wagering requirement: completing the play condition does not increase that maximum.
- Create an account with your name, date of birth and email.
- Enter the code 100GO when claiming the free chip.
- Complete the 30× wagering requirement.
- Keep any eligible cashout within the $100 maximum.
No deposit does not mean no conditions
The free chip has its own wagering rule and cashout ceiling. Read those two figures together before you start playing.
