Two numbers point in opposite directions here. The live floor holds the cheapest games in the building, and bonus terms treat them as the most expensive.
Wagering contribution is the reason. Slots normally count in full toward a playthrough while live tables count a fraction or nothing, usually 10%. Take a 200 GEL bonus at x30 on the bonus alone: the target is 6,000 GEL of turnover on slots and 60,000 GEL at a table counting a tenth. At 5 GEL a hand and 45 hands an hour that is over 260 hours of blackjack, which is not a plan, it is a refusal written as a percentage.
Two more lines bite here. A maximum bet rule caps the stake while a bonus runs, so a table whose minimum sits above that cap is closed until the playthrough ends. And most terms bar low-risk betting, which is what covering red and black at once looks like from the operator's side.
The two products want opposite things. Clear the playthrough on the slots the terms actually count and take a clean balance to the table, or skip the offer and keep every win withdrawable from the first hand, a trade priced by the multipliers the bonus ranking orders operators by.
