casino changed the eligible games list while i was already halfway through wagering

was running through a reload offer, got maybe 55% of the way through the wagering requirements, just grinding my usual blackjack tables, then got hit with a popup saying the game is no longer eligible. checked the terms and the eligible games list really did change, right in the middle of my progress. my play didn’t count for the rest, had to switch to slots to keep going. i tracked everything and i’m sure i did nothing shady, but when i asked support, they just said “terms can be updated at any time.”

now i’m thinking maybe this is more common than i thought. i usually pick casinos based on their blackjack-friendly promos but if they can just change the rules on the fly, kinda blows the whole value. i’ve seen folks get shut out for max betting or obvious bonus abuse but this was just dead regular low-stakes stuff.

has anyone else had their promo conditions change during play? is this a fight worth pushing, or do most folks just take the loss and move on?
