I've noticed that sometimes as soon as I lose the third heart, I lose the lesson. Whereas other times, I can continue without any hearts until I get a 4th question wrong. Why is this?
I usually have an extra heart available - but don't often activate it. So does that mean that if I lose three hearts I can keep on playing without activating my spare until I get another question wrong? So in effect, if I utilise the spare, that's two extra chances I've had? I'm confused now!
Hi Dogstaruk! The correct format of the hearts should allow you with 4 chances. The first three times you get a question wrong, you clear out your hearts. The fourth time you get a question wrong, you should have lost the lesson. I'm afraid that's all I can answer, but have you tried logging out and back in or checking on another computer or device?
