The first criterion for ranking the best online first-deposit casino bonus is the value of the bonus. For instance, online casinos that offer 100% match first bonuses are ranked higher than those that offer only 50% match bonuses.
However, the value of the bonus is also determined by the cash limit of the bonus. For instance, a 100% match up to $50 is less valuable than a 50% match up to $1000. Another criterion for ranking the bonus is the expiry date, the rollover, and the requirements or conditions attached to the bonus. For instance, bonuses with no wagering requirements are more attractive than vice versa.
