Online casinos aggressively market their deposit bonuses, making it seem like they are handing out free money.

The reality is that these promotional funds are heavily restricted by a mechanism called a playthrough requirement.

Explaining the Playthrough Multiplier

This rule specifies the total volume of bets you need to place before the bonus money converts into real cash.

If the terms state 20x on both the deposit ($100) and bonus ($100), you must wager $4,000 in total.

• The goal of the casino is for you to lose the bonus money before hitting the target
• Always check if the multiplier applies only to the bonus, or the deposit + bonus combined
• Understanding this math is crucial to determining if an offer is actually worth taking

Game Weighting and Restrictions

Casinos are smart; they know which games have the lowest house edge, and they restrict them accordingly.

Live dealer games and high-RTP table games are frequently excluded from bonus wagering entirely (0% contribution).

By playing low-risk slots, you can slowly grind through the mathematical requirement and emerge with a profit.
