This depends on the respective online casino. Most bonuses and free spins are mostly only valid in the slot machine area. Bingo is often excluded or only partially credited. We recommend an online casino where there are bonus offers especially for bingo. It's best to do a little research. Find a platform where bingo is explicitly mentioned. After all, there are also casinos where bingo is quite present. There you have a better chance of getting a bonus. You can also read our test reports, where you will always find useful information.
