What is Welcome bonus?
A welcome bonus is a promotional incentive offered to new customers when they register or make a first deposit, often a percentage match of the deposit or a set of free spins.
A common format is a deposit match, such as 100% up to £50, where a £50 deposit is credited with an additional £50 in bonus funds. Others combine smaller matches across several deposits or add free spins. The bonus funds are usually subject to wagering requirements, game restrictions, expiry dates and maximum bet rules.
Regulators increasingly limit how welcome offers may work. In Great Britain, wagering requirements have been capped at 10 times the bonus since 19 January 2026, and offers combining different products, such as betting and casino, are no longer permitted. The Netherlands has heavily restricted bonus advertising.
For news readers, welcome bonuses are a major customer acquisition cost for operators and a focus of advertising regulation. Bonus terms are set by each operator and vary widely.
