    Just what the world needs.

    One year after the world saw the birth of an international icon, the fastest thing alive is back at it again with a new round of ways to end the plot of Dr. Robotnik. Sonic finally encounters one who has super speed just like him, but much more smarts and much less wits than Sonic. Sonic and Tails subsequently become the best known alliance in fiction that possibly is more popular than Mario and Luigi. Let me get my biggest point out of the way. Casino Night Zone? That is a way to treat and get rid of a gambling addiction. It is one of my favorite zones in the existence of Sonic the Hedgehog. Only in this port is the zone improved. Also, Sega is quite cunning to have Knuckles as an available character, deeming it impossible to beat Robotnik in space due to the shortened height of Knuckles' jumps. In reality, it is easy to beat Robotnik as Knuckles. Quite a tricky move by Sega there. This game is just the start of a brand new day for the blue blue. The day has yet to end. There is nothing that needs tone brought to the attention of Sega about this app besides the fact everyone did a phenomenal job making this port. Sonic the Hedgehog 1 was cool, but Sonic the Hedgehog 2 leaves fire in its footsteps. Play the game!

  • By X-da man!oooohhhh yeah!


    I think this app is absolutely great. But the chaos emeralds are really hard to get. Which is not an error. I do like that the cheat codes have not been removed. The debug one does work, but you can’t use it because of the lack of buttons. The one you can actually use is the Super Sonic one. (In no save mode only) When the game starts, after sonic runs around, hit the letters in this order: S-E-G-A (you will hear a ring sound). When the character(s) show up and the text at the bottom shows up, swipe up from the bottom of the screen with two fingers. The level select will show up. Go down to the sound test and play these sound tests in this order: 4-1-2-6. You will hear the sound of Sonic getting a chaos emerald. Proceed to play a level. In the level collect 50 rings, then jump, while in the air, hit the jump button again, and you will become Super Sonic, you have to constantly collect rings to stay super.

    BEST SONIC GAME (but with adds)

    I love the classic sonic series and this game HAS to be my favorite, I still remover when I was young I played this game on the Xbox 360 me and my brother had, I loved being Tails and I liked the fact that there was even a 2 player mode (BTW can we get some of that good 2 player in this app) But here is the catch, when I bought this it was LITTERED with adds, I was thinking “I PAID FOR A GAME WITH ADDS AND I NEED TO SPEND MORE MONEY TO GET RID OF THEM!!!!!” Yeah I thought I was scammed, so I still played the game and then when I was about to defeat the final boss and I had no rings and 1 life left,6 ADDS IN A ROW BABY, THEN IT SENT ME TO AN INTERNET TAB, THAT PAUSED MY GAME AND WHEN I COULD FINALLY PLAY AGAIN, BOOM I DIED so yeah Sega please lower the price of removing adds please to make the experience for the player better for the player, we don’t want another Electronic Arts that litters the game with micro transactions and paying to rid of things that shouldn’t be in the game in the first place, Thank You.

    Great Game but where is 3?

    I love this game, sonic 2 has been my 2 favorite game for a long time. I am now re downloading this game years after its release and its still great, but I still see you haven't made sonic 3 & knuckles yet. Sonic 3 & knuckles is my favorite game ever, and I knew at the time of this games release it may take a while to make the third game but, I'm now coming back 2-3 years later and see no progress. I would love to have my favorite on mobile,But still I look on the App Store only seeing sonic 1, 2, CD, and 4 episode 1 and 2. Why not make sonic 3? I still want to give this game full credit but I would have expected some progress on sonic 3 & knuckles so I'm taking off a star, but anyways this is still a very good game and I'm very happy I can play one of the best classic sonic games on mobile.

    Sega Forever is Denuvo for iOS

    The classic Sonic series was probably one of the first sets of games I've played, and they're probably why I love retro games. The Christian Whitehead ports for iOS are wonderful, and I'm glad to have the old Sonic games on my iPad. I hate it, however, when Sega adds unnecessary garbage like Sega Forever to their games. The mobile port of Sonic 2 was just as great as the original with controls if not better. Since that Sega Forever update, the controls just broke. The d-pad would have a delay of 1-5 seconds before either changing directions or resetting when I let go. The jump button no longer works half of the time, forcing me to die over and over. Even the momentum came off as a bit broken. This makes the whole game nearly unplayable. Nobody likes losing control in a game, and neither do I. The ad issue was moot to me because I paid three dollars before the garbage Sega Forever update. This is why you don't let Sega mess with Classic Sonic. I'm not willing to buy another one of your ports or games unless I know for a FACT that someone more responsible is behind the controls. Get rid of the update! Go back to when it was run by Chris Whitehead. Only then will I put 5 stars, you money-hungry, thick headed, fools.

    A classic re-imagined, but one minor flaw

    There’s not much really to say, it’s sonic 2 with better sprites and visuals, I love it! But..there is one thing I must address, and that is: THE ADS. These things are everywhere, from when you enter a special stage, when you boot up the game, and EVERY SINGLE TIME YOU RESUME THE GAME AFTER PAUSING, THERES AN AD! But I get it, this is a free port and I can pay to have them removed, but, since I don’t have that money, I’m forced to watch 20 seconds of horrible gameplay. That’s not even the worst of it, there is this weird glitch that happens when you start up the game and go to your save files, the game acts like it’s going to give you an ad, but the screen just goes black, and it stays like that until you exit and restart the app, it also happens when I pause and resume the game, so if I grab 3 Chaos emeralds in a stage and pause my game, I’m basically gambling my emeralds. I do not hate this game, and I get why they have to put ads in there, but if you could fix that black screen of death, that would be great! 4.8/5.0

    An ad glitch?

    This is seriously an amazing port of the Sonic 2 game. So good that I will buy the ad free version once I'm allowed to (yeah pretty lame of me to admit). However, in the meantime, there's a bug (or something?) that's bothering me a bit... I don't know if I'm just uninformed about these types of things but whenever some ads play the sound goes out for the whole game?? That's not all, sometimes after the ad plays the screen just goes black (or on worst occasions, an ad is supposed to pop up and it just appears black). Of course I could just restart the app, however, with the frequency of these ads showing, I never know when the glitches (?) are about to occur. Don't get me wrong, I don't mind the ads when I know I'm playing such a good game for free. However, I do mind when they actually affect my gameplay experience this greatly. Then again I almost never invest so much time in an app so I'm new to this kind of thing I guess. I don't know but I just thought I'd drop this by.

    N O S T A L G I A

    You ever get nostalgia from playing a game that was released before you were born? That you’ve literally never played before but you know your parents have? That’s this game. So yeah, since the Sonic movie released, I’ve been playing all these app version remakes. I think they did a really good job converting the controls to mobile, and the video quality is great too. I dunno, I’m not some great reviewer dude, I just wanted to post something here lol. Anyway, I also came here to report a couple problems: 1. Because knuckles’ jump is shorter, you can’t damage the eggman bot from the front in the final boss. Of course, you can hit him from the back, but I don’t think that was what you are intended to do. 2. Tails won’t turn into super tails. He just keeps flying. No matter how many times I double tap, it won’t work. And yes, I had enough rings, but for some reason nothing works. Anyway, aside from obvious ads, it’s a great game. Get it. Nothing much else to say. Ok bye

    Best game I’ve played in a while

    I’ve love sonic the hedgehog And played his games ever since I was eight. So I love this game and everything it has to offer but there is one problem when I try to access debug mode by clicking no save selecting sonic and tails clicking the letters of Sega hearing a ring sound and clicking the start menu with two fingers it starts a normal game and doesn’t bring me to the level select unless you have changed the way you do it this glitch needs to be fixed UPDATE: PLEASE FIX!!!!!!! there was an update that came out not too long ago and debug level select is still broken!!! I click no save I select a character click sega letters in order I tap the screen with two fingers and it brings me to a normal level this is really annoying please fix this!!!!!!!!!!!!!!! If you have removed it update the game so that it’s back if you change the way you do it please let us know somehow!

    Where’s Level Select? What about the iPhone 11?

    Hey everyone from the Sonic 2 Mobile Port Staff. I just want to say you guys did a phenomenal job porting this classic game into HD and making it free (albeit with ads). The only gripe I have is that I can’t seem to get the Level Select to work. When I tap the Sega letters in No Save it plays a ring chime but once I put my two fingers on the bottom it doesn’t take me to Level Select anymore. I don’t know if it was patched out or if I’m just doing it wrong. I’d like a response back if possible. Still, even without Level Select this is an awesome game. Also, please let the game be fixed on the iPhone 11. Whenever a stage is about to begin the yellow icon just sticks out until everything else appears and when I end the stage I can just see Sonic and Tails running in place at the corner of the screen.

    Good remake, bad ad placement

    I am a lucky user who has had Sonic 2 and 1 purchased even when the games were emulated. Then, something amazing happened in 2013. These great games were remade, filled to the brim with features! However, the Sonic 1, 2, and CD remakes took a dark turn in the form of “SEGA Forever.” There are three types of ads in Sonic 2. One when you click on “PLAY GAME,” one between Acts, and one when you...resume the game. SEGA, if you wanna have ads, maybe you can add a mode where the game screen is shrunk a little, but it leaves room for ad banners. And I mean those short rectangular ads. Personally, I’m fine with my Sonic Mega Collection and Sonic Gems Collection discs. And the thing I’m MOST bothered about, I couldn’t restore my precious Sonic 1 purchase. On a side note, SEGA is kinda lying to us. When you “restore the purchase” on Sonic CD (which I didn’t do), there’s still a little Sonic Forces ad in the menu. Just buy a GameCube, PS3, or XBOX 360, guys...I guess this review wasn’t COMPLETELY accurate to my opinion, but hey, you gotta say something! (Note: pls fix mania debug it shouldn’t be this limiting i want more tails/knuckles abuse options)

  • By Little jay lj

    Please fix this advertisement system

    Usually whenever I play this with ads it’s ok I don’t mind advertisements at all, but when ever adds are forcefully popping up at you DURING GAMEPLAY. Then that’s a problem. whoever’s the idiot at SEGA and always wanted the user to play with ads on the Taxman and Stealth ports of the games needs to have a talk with me. Because this ain’t right no one else needs to be put in the same place I was actually going through and I just turn wifi off. but what happens whenever WiFi or cellular data it’s turned off? that’s right A PROMPT PLAYS TELLING YOU TO TURN ON WIFI AND CELLULAR DATA. Meaning it’s required you to actually do this in order to deliver ads to the user playing. Luckily there’s no zero stars function in the App Store so I’ll give the ports a 1/10 because of this stupid advertisement system. Until the day this is fixed or at least ad free WITHOUT THE NEED TO PAY ACTUAL INGAME (or INAPP) MONEY FOR THIS APPLICATION I WONT PLAY IT AGAIN ANYTIME SOON BECAUSE I MAY HAVE AN EPIPHANY AND EMULATE THE ORIGINAL GAME MYSLEF and no one likes me doing that am I right SAKURAI?

  • By Tatetanic

    WAY too many ads.

    Normally I’m okay with ads... when they come after a level or at a stopping/intermission point, like in the original game. But when they come in the middle of GAMEPLAY? That’s ridiculous! Sometimes they even come back-to-back, and once I even got an ad ON TOP OF AN AD! (Yes, i know you can buy the ad-free version, but you shouldn’t have to BUY smooth gameplay!) As an example, during a special stage (in Emerald Hill) I got FIVE ADS right next to each other. FIVE! The gameplay itself is excellent, which is why it’s rated three stars by me, but the ads are the main problem. Please fix this; I would say maybe after each act, but definitely not in the middle of playing the game. As an added request, make the game offline-playable, and I would definitely rate it five stars. Edit: I LITERALLY CAN’T PLAY THE GAME. The thing is, when you get an ad that opens into an internet tab, it pauses the game. When you unpause, it gives you a video ad. Then a new tab ad opens in the middle of the video ad and pauses the game, you unpause, a video ad plays, then a new tab opens in the video ad, etc. The game is unplayable, unless your idea of playing is advancing two frames in between constantly playing ads, and for that, I’m wishing there was a zero-star option.
