Every single online casino uses the promise of massive "free" bonuses to entice new players to register.

It is easy to see a $1,000 welcome bonus and assume you can simply deposit, claim the cash, and walk away a winner.

The catch behind the "free" money is a contractual obligation known as playthrough or wagering requirements.

If you do not understand how these terms work, you will inevitably end up frustrated, feeling like the casino scammed you.

Our guide will explain the mathematics behind playthrough multipliers and how to spot predatory bonus terms.

The Mathematics of the Bonus Catch

A wagering requirement (or playthrough) is a multiplier that dictates how many times you must bet the bonus amount.

If a casino gives you $100 with a 30x requirement, you cannot simply play one $5 hand of blackjack and cash out $95.

In this scenario, $100 x 30 = $3,000. You must place a total of $3,000 in bets before the bonus money is unlocked.

The wagering requirement is the casino's insurance policy, guaranteeing that the vast majority of players will lose the bonus back to the house.

This is why reading the exact multiplier number is critical; a 20x requirement is beatable, while a 60x requirement is practically a guaranteed loss.

How Casinos Double the Wagering Multiplier

You must pay incredibly close attention to whether the requirement applies to the "Bonus Only" or the "Deposit + Bonus" (D+B).

If the terms state the requirement is "30x (Deposit + Bonus)," the math becomes significantly worse for the player.

A 30x (D+B) requirement is incredibly difficult to beat, and most players will lose their entire deposit trying to reach it.

In a non-sticky system, you can withdraw your initial deposit at any time (forfeiting the bonus), giving you an immediate escape hatch if you win early.

Playing with pure, unrestricted cash is almost always a better mathematical decision than accepting a predatory D+B bonus.

The Hidden Restrictions on Bonus Play

Even if you find a fair multiplier, there are two more major rules you must navigate: game weighting and maximum bet limits.

If you bet $1 on a slot, $1 is cleared from your target. However, table games are severely penalized in the weighting system.

This makes it mathematically impossible to clear a bonus using table games before your bankroll evaporates.

The casino imposes this limit to prevent you from getting lucky, hitting a massive win, and then clearing the requirement with a few huge $50 bets.

Successfully cashing out a bonus requires incredible discipline, patience, and strict adherence to every single rule.

How to Read Bonus Terms and Conditions

• What is the Multiplier? Anything between 20x and 40x is standard. Anything over 50x should be avoided.


• Sticky vs. Non-Sticky: Never accept a bonus that legally locks your initial deposit until the wagering is met.


• What is the Maximum Bet? Know the limit (usually $5) and ensure you never accidentally exceed it.


• What is the Game Weighting? Ensure the games you actually want to play contribute 100% to the requirement.


• Maximum Cashout: Ensure there is no ceiling on your potential winnings; winning a jackpot should mean keeping the jackpot.

Wagering Calculation Examples

However, a predatory bonus will simply lock your money in a mathematical prison until the house edge destroys it.

If the terms are hidden, confusing, or written in deceptive legal jargon, simply decline the bonus and play with raw cash.

Only accept bonuses from highly reputable, licensed casinos that offer transparent, non-sticky terms.
