Seraphon

It's all about an underwater game and getting the password.
This game was worldwide and you could win a lot, but it was very risky and dangerous for almost everyone. The game is about three people: one is in a room where everything is burning while the other two have to swim with strength and speed. But the trouble starts when you reach a room. This room has buttons; everything is slippery and slimy. If you step on a single button, you will awaken a large, hungry snake, and at that moment you have to swim out faster than a horse, car, etc. But your partner will die. However, if you manage to get to the bottom, you will find the password. You have to memorize it very well since it will be letters and numbers together.
