The second chance is present in all game modes and will allow you to continue playing despite answering incorrectly. You will have two options to not lose your turn; you can pay gold bars or you can see an ad.
If you decide to use gold bars, keep in mind that the cost will increase each time you use the second chance feature. With an initial price that will depend on each game mode, it can be used as many times as you want, as long as you have gold bars to pay the price.
If you decide to use the ad option, you will have the possibility to continue playing for free, but you will only be able to use this option once per turn.
