What Is a 400 casino bonus?

A 400 casino bonus is a promotional offer that may add bonus funds to a player’s account after the stated qualifying steps are completed. Casinos provide these rewards to welcome new customers, encourage deposits and make their games more appealing. A 400 deposit bonus can offer extra value, but players should claim it only after reviewing the full terms. Once activated, the 400 casino bonus usually appears in a separate bonus balance and may be used on eligible games. Winnings can generally be withdrawn only after the wagering requirements have been met. Deposit thresholds, maximum bonus limits, eligible games, stake caps and expiry periods vary by casino, so always check the applicable conditions first.

Important T&C for 400 casino bonus

Before claiming a 400 deposit bonus, check the wagering rules, withdrawal limits, eligible games, expiry date and maximum bet. These terms determine how the offer can be used and whether bonus winnings may be withdrawn.

Wagering Requirements

Wagering requirements state how many times you must play through the bonus, or the bonus and deposit, before withdrawing related winnings. For example, if a £400 bonus has a 30x wagering requirement applied only to the bonus, the required turnover is £400 × 30 = £12,000. Always check which funds count.

Withdrawal Limits

A withdrawal limit caps the amount you can cash out from bonus winnings. Any balance above the stated limit may be removed when a withdrawal is requested. Check whether the cap applies per promotion, transaction or account, and whether verified deposits are required first.

Restricted Games

Restricted games are titles that cannot be played with bonus funds or do not contribute towards wagering. Some games may count at a reduced rate. Playing an excluded title can lead to bonus cancellation, so review the eligible game list before placing a bet.

Bonus Expiration Date

The expiration date is the deadline for activating the offer or completing its wagering requirements. If the deadline passes, unused bonus funds and associated winnings may be removed. Confirm when the validity period begins and whether separate deadlines apply to claiming and wagering.

Bet Limits

Bonus bet limits set the maximum stake allowed while wagering promotional funds. The limit may apply to each spin, game round or combined bet. Exceeding it can invalidate the promotion and related winnings, so check the applicable cap before playing.
