Sonic Freehand, also known as Sonic the Sketchhog, is a 2D side-scroller platform game for mobile phones and iOS devices. The game features Sonic in a hand-drawn doodle style defeating Badniks like Crabmeat & Chopper as he advances his way through a drawn level. It was only available for the month of July 2010.
A port of this game was later made available for iOS devices, as part of the Sonic 20th Anniversary app.
The game is only one long level, like all score attack-genre games. The level gets progressively harder, as shown by the text at the top of the screen. The difficulty levels, in order, are as follows:
- Very Hard
The game is relatively simple to play: Sonic automatically runs through the level, and the player must tap the screen in order to Spin Jump. However, the flat landscape is strewn with dangers such as pits full of spikes, bottomless pits, and Badniks. Despite Badniks being a danger, they can also be very helpful, as jumping at the correct time may result in crossing a pit by using Choppers as "stepping stones". This method can also help Sonic reach high ledges.
Sonic can also collect Rings in this game. As long as Sonic has at least one Ring in his possession, he will survive running into a Crabmeat or falling into a pit of spikes. It is not until the "Very Hard" difficulty that pits become bottomless. Falling into a pit, regardless of Ring count, will result in a game over.
- A mug featuring Sonic the Sketchhog was available to buy for 1,500 yen at the 2013 Tokyo Game Show.
- The game's menu and level music sounds like a music box version of the Sonic the Hedgehog 4: Episode I menu and Splash Hill Zone, respectively.
- In Sonic the Hedgehog: The Movie, there is a scene where Hyper Metal Sonic believes he has killed Sonic. Hyper Metal's heads-up display then blinks a Sonic Freehand-like Metal Sonic celebrating while Tails panics and Sonic dies.
- A promotional Nike Flash game with similar gameplay to Sonic Freehand named Sonic x Vapor was later released in 2012.
