Rollover in betting

Rollover is how many times a bonus must be wagered before it can be withdrawn. A ₦10,000 bonus with 5x rollover requires ₦50,000 of qualifying bets.

Each qualifying bet chips away at the requirement, but only bets meeting the minimum-odds rule count, and every cycle of turnover costs you the bookmaker margin. That is the hidden price of a bonus: at 5% average margin, a 5x rollover expects to consume roughly 25% of the bonus in vig before you ever reach the withdrawal threshold.

Required turnover = bonus x rollover multiple. Expected cost ≈ turnover x market margin.

A ₦20,000 bonus with 6x rollover at minimum odds 2.00 requires ₦120,000 turnover. At a typical 5% market margin, expected loss during that turnover is around ₦6,000 — so the realistic value of the "₦20,000 bonus" is closer to ₦14,000, before considering the time limit.

Rollover is where bonus marketing meets arithmetic. Comparing offers on headline size instead of on rollover, minimum odds and expiry is how bettors end up locked into unprofitable turnover.

Rollover terms vary sharply between Nigerian operators — the same nominal bonus can carry 3x or 10x. Always divide the bonus by the required turnover to get the real rate before depositing.

• Placing bets below the minimum qualifying odds, which contribute nothing.
• Ignoring the expiry window and forfeiting a partially cleared bonus.
• Chasing a large bonus at a book with poor prices, which costs more in margin than the bonus is worth.
