Welcome to the world of logic puzzles! We'll start off easy, so here are your first questions.

1. I flip 2 coins without you seeing them. I look at the coins, and tell you:"At least one of the coins is heads". What is the probability that the other coin is also heads?

2. You have 3 pairs of blue socks, 2 pairs of green socks, and 1 pairs of red socks in a drawer. Without looking, how many socks do you have to take out to be absolutely certain that you have a pair of same-colored socks?

Our purpose is not to give you an alternate world to escape your real one, its not to give you a casual game to relax, but to educate your mind in a way that is not normally possible. This "game" is highly addictive and might change you forever. Do not just play it ... learn from it ... because "it" learned from you.
