Roulette: check the wheel
A single-zero wheel has one zero pocket; a double-zero wheel includes both 0 and 00. The layout affects the available outcomes. Read the table’s rules and payout information rather than assuming that two roulette rooms are equivalent.
Blackjack: table rules change decisions
The dealer’s soft-17 rule, blackjack payout and the availability of doubling or splitting can differ. Side bets have separate rules from the main hand. Check these details in the help panel for the particular table, not in an unrelated tutorial.
Live presentation and round records
A live video feed and the recorded game state are different parts of a table interface. If the feed freezes, check the round history before repeating an action. A pending result is not an invitation to submit the same action again. Contact the operator with the round reference if the record is unclear.
