Wagering requirements at Casoola: how to calculate them step by step

The wagering requirement is the most important and most misunderstood bonus rule. This page is the maths part of the bonus section on casinocasoola.biz: it shows how the required turnover is built, what makes it grow and how to estimate its cost in advance. Every number here is an illustrative example, not Casoola's terms; the real multiplier is set in the current offer.

The basic formula: multiplier × base

The required turnover is made of two numbers: the multiplier (for example 35x) and the base it applies to. The base can be the bonus alone, or the deposit and the bonus together. With the same multiplier, that difference doubles the turnover, so it is the first thing to find in the terms. The table uses a €100 deposit and a 100 percent, €100 bonus (illustrative example, not Casoola's terms).

Contribution multiplies the turnover

Not every stake clears the requirement equally. If a game counts 10 percent, only €0.10 of every €1 staked is credited to the progress. The rows below show the real stakes needed for €3,500 of turnover at different contribution rates (illustrative example, not Casoola's terms).

The practical conclusion is simple: with a bonus balance, choose a game that counts in full and is not on the excluded list. Both the contribution table and the excluded games are in the bonus terms.

The expected cost: what the formula does not say

Turnover is just a number; your wallet cares about what clearing it costs. Over the long run the house edge – 100 percent minus the RTP – stays with the casino on every stake. €3,500 of turnover at 96 percent RTP means an expected loss of about €140; at 97 percent it is about €105. If that is more than the bonus, the bonus loses money on average; if it is less, it gains. Check the RTP in the game's info panel, because the casino can pick between several configurations offered by the studio.

Volatility sets the spread. On an extreme-volatility slot such as Mental or Fire in the Hole 3, the balance often runs out before wagering is complete, while a rare large hit is possible in exchange. On a medium-volatility game like Wild Bandito the ride is steadier.

Which money is used first?

Terms handle the balance in one of two ways. In one, your own money is used first and the bonus only comes in afterwards; under some terms, if you win before touching the bonus, you can drop the bonus and withdraw. In the other, both balances merge and the wagering applies to the whole amount. Which model applies to a given Casoola offer has to be read from the terms; if it is unclear, ask support for a written answer.

Tracking your progress

Note when you activated the bonus and how much turnover is required, and compare it with the progress shown in your account from time to time. If something does not add up – a game counting less than you expected, for example – stop and clarify before you continue. As the deadline approaches, do not raise your stake above the maximum bet: that is the most common way to lose bonus winnings.
