Nickelodeon's Hardest Game Ever is a SpongeBob SquarePants online game.
Like the name suggests, it is an extremely difficult game. It uses a variety of different Nickelodeon animated characters. Nick.com describes the game as "Played all the games on the site? Are they all too easy for you? Well ok, Superstar Champion Gamer, How about you play Nickelodeon's Hardest Game Ever!"
The game is quite simple, all you need to do is move your mouse, which controls a character. The starting character is SpongeBob and the rest are unlockable, from a variety of different shows such as Fairly OddParents and Sanjay and Craig. Balls of slime and other things will fall down from the top of the screen and using your mouse, you need to direct your character (who has a small little platform on their head) to bounce the ball off of the little platform. While it looks quite easy on the surface, throughout the levels, the game gets progressively harder, and to make it even more difficult, once you die, you need to go back to the start.
This game contains many special features, which include unlockables. The unlockables are divided into 4 parts, which are characters, worlds, bubbles, and pickups.
