The way to end the fifth game without any casualties (spoiler)
I talk about the Glass stepping stones game.
As you know you must take of your shoes before go up to the glass tiles but there is no rule you can't take the shoes with you.
So the way to win the game is use the shoe to break the glass, if the glass don't break or cracks, it is clear and you can jump. The first step is the most easy, you lying down on the floor and hit the glass with your shoe. Then it's more scary but still possible, you do the same from each tile, you lying down on the safe tile and hit other glass with your shoe.
Two players can be in the same tile, so one of them can keep the other player from felling.
