Bonus Crab: what it is and which casinos have it

What you are actually getting

The Bonus Crab is a prize grid. Qualify for it and you get one pick, which reveals a reward — free spins, bonus cash, or a sportsbook free bet depending on what you land.

The important structural point is that it is additive. It does not come out of the €500 match or the 200 free spins; it is credited alongside them. Three of the eight casinos in our comparison run it: BassBet, Spinanga and Buran Casino.

The €10 tier is the interesting part

At BassBet and Spinanga the Crab has its own, lower deposit threshold. A deposit of €10 to €19 sits below the €20 bonus minimum, so it earns no match and no free spins — but it still earns the Crab pick.

That makes a €10 deposit a genuinely cheap way to try a site. You will not get the welcome package, and you should not expect to, but the deposit is not entirely without return.

Buran includes the Crab with its standard welcome package rather than advertising a separate low tier.

Do not let it decide anything

The prize is randomised, so its expected value cannot be calculated from the outside and is certainly not large enough to outweigh a €100 difference in sportsbook cap.

Use it as a tiebreaker, never as a reason. BassBet and Spinanga are worth choosing because they pay €200 on the sportsbook rather than €100 — the Crab is a bonus on top of that reasoning, not a substitute for it.
