What Is a 400 casino bonus?
A 400 casino bonus is a promotion that adds bonus funds after a qualifying action, such as registering or depositing. Casinos offer it to attract new customers, reward existing players and encourage play on eligible games. Claiming a 400 casino bonus can provide more funds to explore a site, but its value depends on the terms. The bonus usually appears in a separate balance and may be used before cash funds. Wagering requirements determine how much must be played before winnings can be withdrawn. Deposit rules, eligible games, maximum stakes, withdrawal caps and expiry dates may also apply. Players should read every condition before accepting a 400 casino bonus.

Important Terms and Conditions
Before claiming a 400 casino bonus, review its wagering rules, withdrawal limits, eligible games, expiry period and maximum bet. Conditions vary between casinos and determine how bonus funds and any associated winnings can be used.
Wagering Requirements
Wagering requirements state how many times the qualifying amount must be played through before winnings can be withdrawn. For example, if a £100 qualifying amount has a hypothetical 30x requirement, you must place £3,000 in eligible wagers: £100 × 30. Always check whether the requirement applies to the bonus, deposit or both.
Withdrawal Limits
A withdrawal limit caps the amount of bonus-related winnings you can cash out. Any winnings above that limit may be removed. Casinos may also set minimum withdrawals or payment-specific limits, so check the applicable terms before playing or requesting payment.
Restricted Games
Restricted games are titles that cannot be played with bonus funds or do not contribute towards wagering. Some games may contribute at a reduced rate. Playing an excluded title can lead to cancelled winnings, so confirm game eligibility first.
Bonus Expiration Date
The expiration date is the deadline for using bonus funds or completing wagering requirements. If the deadline passes, unused funds and related winnings may be removed. Check when the validity period begins and how much time remains.
Bet Limits
Bonus bet limits set the maximum stake allowed while wagering is active. Exceeding the limit may breach the terms and result in forfeited funds or winnings. The cap may vary by game or bet type, so verify it before placing wagers.
