Hello Radka
Thank you for your question! The difference between the wagering formula and the standard wagering requirement is that the wagering formula doesn't have a fixed wagering number, it depends on the house edge factor. Our formula is bet * house edge * 50%. House edge is a variable factor here, so we can't say how much wager you will need to make, it depends on the games you play.
Of course, let's use this example:
You registered on Chipstars and made your first deposit of 100 EUR. You will get your 100 EUR on the real money balance + you will get your 100% bonus (you can get up to 300%, depending on your deposit, if you deposit more, the bonus will be higher. This is also the good thing about our bonus, you can get large bonuses, up to 73k in total for our welcome pack). So, you have 100 EUR of real money and 100 more which you can unlock by playing. Now you started playing, you won something and now you have 500 EUR on the account, and the wager to unlock locked 100 EUR is at 32% currently, for example. You don't want to play anymore, you want to withdraw your 500 EUR. You are free to do that whenever you want, doesn't matter if you didn't unlock your bonus money. This is the reason we calling our bonus "wager-free", wagering will not bind you to anything, and you will not have any problems until you wager, which you can have on some other platforms. Now, that you made the withdrawal, you still have unlocked 32% of your bonus. After 3 months, you decided to play again, and you made another deposit of 200 EUR. You got a 200% bonus for this (400 EUR locked). Now you have 400 EUR in your account and you started playing. Your first bonus will continue with unlocking again (it will never expire, you have unlimited time to unlock your bonus) and after some time you have unlocked 100% of your bonus for the first deposit. Now 100 EUR is automatically transferred to your real money balance and you can do whatever you want with this money. You can withdraw it, keep playing, or do whatever. Remember that you have a bonus for 2nd deposit too? It will automatically start with unlocking after 1st bonus is unlocked, if you keep playing on Chipstars, you will unlock it for sure at some point, so this bonus is the bonus in the real meaning of this word, You as a player have only benefits from it, there is no single downside for you, nothing like max cashout, expiring, bounding, etc.
