House edge is the operator’s theoretical average advantage on each wager under specified rules and strategy. Expected cost grows with total money wagered, not just the opening balance.

Expected cost: the practical details
A 1% edge over $10,000 of cumulative wagers implies $100 theoretical loss, even if the account began with much less and funds were recycled through many bets.
Key distinctions
- Expected loss equals turnover multiplied by house edge.
- Faster games create more turnover per hour.
- Short-term results can be far from expectation.
Put the information to use
- Find the exact rule set.
- Estimate bets per hour.
