ERROR bonuses
ERROR’s offers change, so the single source for bonuses is the Promo page. This page only points there rather than duplicating the information.
Where the current bonuses are
The Promo page shows the current welcome package, its amount and terms, and cashback when it is running. A bonus that needs no deposit is credited right away; a deposit bonus is credited with your next deposit of at least the minimum in its terms.
The terms of each offer are stated on the offer itself on the Promo page. There is no single set of terms for all bonuses at once — they differ between promotions.
A question about a bonus?
If an offer was credited not as you expected, or you need help with the terms — message the support chat.
