Coin Flip

The Coin Flip is an obstacle, firstly introduced as the seventh obstacle in Stage One on American Ninja Warrior 7, replacing the Spinning Bridge from the past three American Ninja Warrior seasons.

Competitors must run across three free-floating disks while maintaining their balance, in order to reach the landing platform. The middle disk was lower than the other two disks, causing trouble for some competitors when they were leaping to the third disk. Not landing on the center of the disk would cause it to flip forward or backward.

Although only two competitors failed on this obstacle, it was notable for eliminating David Campbell (in a similar fashion with his Spinning Bridge fall on American Ninja Warrior 4), making it his fourth consecutive Stage One failure since American Ninja Warrior 4, which eventually would end on American Ninja Warrior 9. It also eliminated Justin Gielski, who tumbled down. Like the Triple Swing, the obstacle was only used once, and was replaced by the Broken Bridge on the next season.

A similar obstacle to the Coin Flip (called as the Diamond Dash) would later appear as the fourth obstacle on American Ninja Warrior 10 in Minneapolis and American Ninja Warrior 11 in Los Angeles, except the disks' shape was changed to diamond and the number of disks was increased to 4.

Ninja Warrior UK
The Coin Flip appeared as the third obstacle in the finals' Stage 1 on Ninja Warrior UK 3, and all competitors who attempted the obstacle, could complete it.

Then, the obstacle appeared again as the third obstacle in Heat 2 and Heat 4 on Ninja Warrior UK 4 and in Heat 2 on Ninja Warrior UK 5. This time, the number of disks was increased to 4.

Ninja Warrior Poland
In Ninja Warrior Poland, Coins appeared as the third obstacle of all Heats (except for Heat 2 and Heat 6). The obstacle consisted of 3 coins. The center disk was suspended lower than the others as usual, making it difficult to jump. Then in Ninja Warrior Poland 4, this obstacle appeared as the second obstacle in the semi-finals (This time the middle disk was suspended higher than the first and second).
