He told presenters Amanda Holden and Jamie Theakston: “I came here for the experience, not coming here thinking I was going to win.
“It’s just surreal at the moment. It’s crazy, crazy times.”
This year’s Make Me A Millionaire competition was launched in February and over the last three months winners have been able to choose to either take that day’s prize money or enter the final to win the £1 million.
Mr Clymer turned down £2,000 to enter the live final, saying he wanted to have the opportunity for a day out at Heart’s Leicester Square studios in London.
During a dramatic live finale, 39 people in the running for the top prize were whittled down at random to enter the Make Me A Millionaire vault.

The finalists each chose a numbered safety deposit box, with only one containing the grand prize, chosen by Mr Clymer, who based his decision on his daughter’s birthday.
He video called his children live on air including 11-year-old “lucky-charm” Alisha.
His partner of 20 years, Martyne Thompson, said: “I’m in shock. I honestly didn’t think this would happen. I was just looking forward to a nice day out.”
The couple plan to take a holiday before buying their family home in Kent, which is currently rented.
Holden, who donned a red sparkly dress for the occasion, said: “Heart’s Make Me a Millionaire has captivated the nation for the past 15 weeks, culminating in the most spectacular grand finale this morning on Heart Breakfast.
