Sega's blue mascot, Sonic the Hedgehog, made his Genesis debut in '91, speeding onto the 16-bit scene as a challenge to Mario. Shining as a swifter, slightly edgier take on Nintendo's prized platformer, Sonic made gaming a bit faster and more exciting.

This renowned franchise -- like the company behind it -- has been through a roller coaster ride of ups and downs. Yet the Hedgehog has seen something of a renaissance of late. The hype surrounding Sega's "blue dude with attitude" seems to be in full swing with the appropriately-named Sonic Mania and the recent film adaptation starring Jim Carrey as Sonic's evil nemesis, Dr. Robotnik.

Thus, now would seem as fitting a time as ever to take a trip back in time and revisit these games. Join us as we rank each Sonic title released on the Genesis from worst to best.

7 Sonic Spinball

Considering Sonic is known for taking on a spherical form and rolling/dashing around, it would seem the blue hedgehog would make a terrific fit for a pinball "spin" off. This is especially true given some of the level design in the main games which resembles -- and even directly takes on -- the pinball motif.

And while this pinball game has its moments, it's received some mixed reviews for its tepid gameplay compared to the mainline Sonic games. Aside from some colorful level design and charming Sonic themes, we're still dealing with pinball - and there's only so much you can do with such a concept. The repetitious nature doesn't exactly capture the fast and forward-moving sensibilities of Sonic.

6 Dr. Robotnik's Mean Bean Machine

Along with games like Columns, Sega utilized the Compile-developed Puyo Puyo to round out its Genesis lineup in the face of the Tetris phenom on Nintendo consoles. But given its Japanese-heavy themes, Sega "Westernized" the game by slapping a Sonic -- specifically the villain Robotnik -- overlay on top of this established puzzler.

Those looking for heavy Sonic influences are likely to be a bit disappointed here. Yet, that's not to say Mean Bean Machine isn't good enough on its own merit. The goal is to shuffle around colored gels - or, in the case of this version, "beans" - and eliminate them by matching the colors and triggering combo chains. It's a simple concept, but it's one that's both fun and addictive.

5 Sonic 3D Blast

This '96 rendition of Sonic tends to get overlooked, thanks to its unique isometric view and its release at the tail-end of the Genesis system's life. It was also quickly brought to the short-lived Saturn, which also did little to garner success. Basically, it was a weird period of transition for Sega, and the industry at large. But after its subsequent release on various compilations and digital distribution platforms, more and more are realizing what a blast 3D Blast can be.

Sure, the pseudo-3D concept can feel a bit forced and out of place. Still, those willing to adjust to the odd, occasionally disorienting style will find more of that same fun Sonic gameplay with a unique spin. This is even the case despite the absence of the cool 3D bonus stages on the Genesis version compared to its Saturn counterpart.

4 Sonic & Knuckles

Sega added yet another colorful character to its Sonic lineup with the debut of Knuckles the Echidna in 1994's Sonic 3. Taking his place as something of a counterpart to Tails, this echidna brute is a powerful fighter who likes to throw around his spike-laced fists. Initially tricked by Robotnik into fighting against Sonic, Knuckles soon becomes a useful ally. This game - developed along with Sonic 3 - marks the first major role for the character, and it's a great one. Released in late '94, Sonic & Knuckles eventually was exposed to a wider audience with its release on XBLA, the Wii Virtual Console, and as a bundle with Sonic 3 on Steam.

The game is essentially a continuation of Sonic 3, and thus sports some similar gameplay -- though perhaps not quite as memorable, especially with the absence of Tails. Still, playing as Knuckles offers plenty of enjoyment. He can perform mid-air drifts and climb walls, though he also feels more weighty with his shorter jumps.

3 Sonic The Hedgehog

Sonic Genesis Green Hill Zone

Despite feeling a touch dated on account of its '91 release - and the absence of Sonic's trademark spin dash, you have to tip your cap to the iconic debut for Sega's blue hedgehog. This platformer changed the game with its blend of fast-paced insanity and solid mechanics. You had the catchy tunes of Masato Nakamura and some colorful environments that are truly impressive for a game that's nearly 2 decades old.

Sonic 1 laid the foundation from which Sega would build upon in follow-up releases. It was the game that revitalized their Genesis, after a tepid start following the uninspired Alex Kidd - which was the original mascot meant to take on Mario. From the moment we took off running in Green Hill zone, we knew we were in for a wild ride with this gem.

2 Sonic The Hedgehog 3

Believe it or not, this was initially meant to be an isometric romp in the vein of Sonic 3D Blast, but the notion was ditched following time restraints and production costs. It's probably a good thing those plans fell through, considering the quality of this refined 2D platformer from '94. Sonic 3 contains those same Sonic-style thrills and delightful side-scrolling gameplay, which is fleshed out and refined thanks to years of seasoning from Sega.

Not only do you actually have a narrative present, but you finally have a convenient save system. You've got some impressively large zones, rich and colorful backdrops, and the addition of elemental shields. Tails also now has the satisfying new ability to fly and swim. These elements, coupled with the classic gameplay, give Sonic 3 a great blend of retro and modern sensibilities.

1 Sonic The Hedgehog 2

This follow-up to the breakout hit on Genesis had a lot of hype to live up to, given Sega's marketing machine and the build-up to "Sonic 2sday;" the first simultaneous worldwide launch of a video game.

Much to the delight of fans, the studio delivered on November 21st, 1992, with what's still regarded by many as the peak of the franchise. You have the addition of Tails to mix things up. Sonic 2 also introduces the enjoyable spin dash, to keep that velocity up there and get Sonic zipping across ramps, hills, and loops. You have a great soundtrack, and some of the most lavish, intricate level designs ever, with memorable zones like Casino Night. This delightful platformer hits the ground running and never lets up.
