[Python] How do I access specifically keys and values from CSV files?

I have a CSV file keeping track of people's score in a game. I read it with csv.DictReader(). How do I create a dictionary with the keys being the names, and the value being the scores?

CSV file example:

name,Game_1, Game_2, Game_3
James,3,7,4
Charles,2,3,8
Bob,6,2,4


Note: the game names can change, and amount of games too..

Code Example:

# Dictionary to load scores into
score_sheet = {}

# Read CSV file into memory
with open("scores.txt") as scores_file:
reader = csv.DictReader(scores_file)

list_of_games = reader.fieldnames[1:]

# Load each row seperately
for row in reader:
for game in list_of_games:
score_sheet[row[0]] = {row[game]:row[game[1]}



# Experiment 1
# Load each row separately
for row in reader:
score_sheet[row[0]] = row[1]


# Experiment 2
for row, value in reader:
print(row, value)


Desired output:

score_sheet = {
'James':{'Game_1':'3'}, {'Game_2':'7'}, {'Game_3':'4'}
'Charles':{'Game_1':'2'}, {'Game_2':'3'}, {'Game_3':'8'}
'Bob':{'Game_1':'6'}, {'Game_2':'2'}, {'Game_3':'4'}
# Optionally:
# name:[{game:score}, {game:score}, {game:score}]
}


Errors:

score_sheet[row[0]] = {row[game]:row[game[1]}
# ^^^^^^ KeyError: 0

score_sheet[row[0]] = row[1]
# ^^^^^^ KeyError: 1


for row, value in reader:
print(row, value)
#
# for row, value in reader:
# ^^^^^^^^^^
# ValueError: too many values to unpack (expected 2)
