When you decide to play at Casumo online casino you will not be required to use any promo codes whatsoever. Nowadays, most welcome bonuses can be accepted when you make your first deposit.
Generally, sites that offer promo codes are the ones that host multiple gaming platforms and by giving codes they can differentiate between each promotion. You will receive these promo codes through promotional mailing lists in most cases.
The moment you sign up for Casumo you will receive a very generous welcome package consisting of a deposit match bonus up to $300 and 20 free spins. The free spins can be used on one of the most popular online slots, Starburst and the first deposit is matched 100%. You must wager the bonus amount 30 times before you can make a withdrawal, and the same goes for the free spins. What you need to remember is that not every game contributes the same way towards the wagering requirements though.
When you have a bonus active, then 50% of your bet will be sourced from your bonus funds and 50% will be sourced from your cash funds.
