You are standing in front of giant hourglasses, more or less filled with precious stones, depending on the number of points the Houses have got.
The Ravenclaw hourglass has blue stones, Hufflepuff have yellow ones, Gryffindor red and Slytherin green.
Each House starts with 100 points every year.
I will edit this thread as points come and go.
Ravenclaw : 50
Hufflepuff : 100
Gryffindor : 50
Slytherin : 100
