The remaining 10 acts performed Tuesday night, and now it is up to American voters to help decide the grand prize winner for "America's Got Talent" Season 10, which will be announced Wednesday night.

Who will win? The competition was fierce. From the fun antics of Piff the Magic Dragon to the musical energy of The CraigLewis Band, it is difficult to predict.

Let's review Tuesday night's performances to make a prediction of which act will take home $1 million and headline "America's Got Talent Live!" in Las Vegas, Nevada, Oct. 22-24.

Ventriloquist Paul Zerdin

Ventriloquist Paul Zerdin kicked off Tuesday night's competition with an act including his two dummies, the adorable one and the creepy-looking bald baby, which praised him before singing a Spice Girls song.

Next, Zerdin introduced a new dummy who is the grandfather of the other two. A joke about confusing his hearing aid with his suppository made judge Heidi Klum laugh. He eventually had four character dummies interacting with him on stage at the same time, which was impressive.

Piff the Magic Dragon

Piff the Magic Dragon had judge Howie Mandel autograph a $20 bill, which he magically transformed into a voucher for one free magic trick performed by his sidekick Chihuahua, Mr. Piffles. Piff handed Klum a small bag. He took one of her rings and tied it to the dog's neck. He loaded Mr. Piffles into a small cannon, which fired a stuffed animal version of the dog across the stage.

Piff laid a sheet over the fake dog and turned him into Mr. Piffles. He asked Klum to open the bag which contained two walnuts, joking that they formerly belonged to Mr. Piffles. Klum chose one walnut. Piff cracked it open and revealed Mandel's autographed $20.

The end of Piff's act was impressive, but was it enough to secure the win?

Mentalist Oz Pearlman

Oz Pearlman asked all of the judges to swear they were not in on the magic trick he was about to perform. To prove it, he asked the judges to think of a loved one or pet to swear against. Stern picked his late bulldog. Klum swore to Jennifer Love Hewitt. Mel B. chose her husband. Mandel picked Mel B.'s daughter, Angel.

Next, Pearlman asked the judges to sit in four covered chairs on stage in a random order.

He had five envelopes. He had each judge pick one. They opened the envelopes to reveal four X's. Pearlman opened his envelope to reveal a picture of his face. The judges stood up and their chair covers were removed to show that the chair color matched the color of their respective papers. Pearlman then turned the picture of his face to show a list of each loved one or pet the judges' had chosen earlier.

The judges and audience were speechless. It seems that he can really read minds.

Magician Derek Hughes

Derek Hughes used a length of rope to make a "square knot," which he joked he'll be performing at his Vegas show. He conjured up a DJ and backup dancers out of thin air. He pulled out three pieces of rope and incorporated Mandel into the act of making them change lengths.

At the end of the act, he had judge Howard Stern cut a piece of rope in half, which he reconnected. It was a simple magic trick that fell flat. He should have ended his act in a more spectacular way.

Singer Benton Blount

Country crooner Benton Blount sang One Direction's "Story Of My Life" with a huge voice that forged an emotional connection with the audience. Benton's outstanding performance of the song impressed the judges.

Stern said that Benton looks and sounds like a star, though the first verse of the song was flat. Mel B. called his act perfect and declared herself a fan. Mandel said he has genuine likability.

Comedian Gary Vider

Gary Vider joked about his career as a dog walker and his roommate, Greg, who is now riding his coattails into the coolest clubs. He joked about North Korean hackers getting him out of debt.

"I'm in a long-distance relationship; I have to stay 1,000 feet away," was one of his funnier lines of the act that made the audience chuckle.

Vider's act was fun but not the most riveting of the night.

Mandel gushed over Vider's performance. Klum congratulated him for making it to the finale. Mel B. praised him for being consistently funny. Stern compared him to comedian and actor Woody Allen.

The CraigLewis Band

The Atlanta-based duo sang "Beggin'" by Frankie Valli and the Four Seasons. Their energetic performance garnered a standing ovation from the audience, but will it be enough to hook voters?

Stern shouted that they are stars who took things to another level. Klum, praised their showmanship and energy. Mel B. said they "brought the house down" and compared them to special guest performers instead of talent show contestants.

Stevie Starr - The Professional Regurgitator

The Professional Regurgitator started his act by swallowing five thumb tacks, followed by a strong magnet. He asked how many thumb tacks Klum would like stuck to the magnet. She said four. He coughed up the magnet with four tacks, followed by the last one.

Stevie Starr had "America's Got Talent" host Nick Cannon help him with the remaining part of his act. He swallowed lighter gas. Cannon tested that there were no leaks by placing a flame in Starr's mouth. Starr released of the gas onto the lighter to show a fireball before regurgitating the gas in a bubble -- amazing. Cannon lit the bubble into another fireball, along with Starr's arm, which we're not sure was supposed to happen.

Klum called Starr "a million-dollar act," while Mel B. dubbed him a showstopper.

Stand-Up Comedian Drew Lynch

Drew Lynch's act closed the "AGT" finale. The stuttering comic came onto the stage with the song "Call Me Maybe" playing. He joked that he's not sexually active because he's saving money. He explained how difficult it is to give out numbers and email addresses because of stuttering. He also joked about his real-life girlfriend, Veronica.

Stern was not a fan of Lynch's self-laughter during the act, something he told Lynch previously. He did praise Lynch's writing. Mandel said Lynch trumped the other comedy acts. Mel B. wanted more, while Klum declared that no matter what, he is already a winner.

Uzeyer Novruzov, the talented circus performer who uses ladders in his act, was injured and unable to perform to his fullest.

Who Will Win 'America's Got Talent'?

The viewing audience and judges will decide with their votes, but the strongest contenders seem to be Zerdin, Piff, The Professional Regurgitator and Lynch.
