Sonic Speed Simulator[1] is a multiplayer online game in the Sonic the Hedgehog series developed by Gamefam Studios and licensed by Sega. It is freely available as an experience on the Roblox platform. It was initially released on 30 March 2022 as a paid beta, and then later released publicly for free on 16 April 2022.[2] The game is actively updated, with special updates being regularly released after milestones are reached—usually involving a set number of likes.[3]
Gameplay

Sonic grinding down a Grind Rail in Green Hill, the first world in the game.
Sonic Speed Simulator is a 3D, third-person platformer game that features open worlds and multiple playable characters. The player's Roblox avatar is unlocked by default, while the other characters, such as Sonic, Tails, and Knuckles, can be unlocked through cards found in all the worlds. In a similar vein to Sonic Adventure 2, the playable characters possess a plethora of moves such as the Spin Jump, Spin Attack (referred to as the "Spin Dash"), Spin Dash (referred to as the "Spin Dash Charge"), Jump Dash, and Homing Attack, with the noticeable absence of the Boost.
The game is about traversing open worlds at high speed while, in a similar fashion to other simulator games found on Roblox, continually upgrading the player character's abilities. Unique to this game, the player can find multicolored Chaos Orbs scattered around the world which gradually increase their Experience Points (XP) when collected. The playable character also gains one XP for each step they take or through purchases from in-game shops. Sky Rings, also unique to the game, grant large amounts of XP when traveled through. Gathering enough XP will increase the player's level, increasing the following parameters:
- Speed: Determines the playable character's maximum speed. Speed starts out low but can get exponentially higher as a player progresses with the game. At higher speeds, players can go through loops, launch themselves from slopes, and run along walls. Speed also affects a player's Spin Dash and Homing Attacks. There is a meter at the bottom left corner of the screen that displays a player's speed in MPH.
- Power: Determines the playable character's jumping height. Power can reach a maximum of 100. It helps the player reach Sky Rings or higher parts of worlds. A high Speed and Power parameter, combined with a well-timed Spin Dash on a slope, will let a player reach notable heights.
When leveling up, the maximum XP cap increases by a bit for the next level and a small text portion will be appearing on the HUD that tells of the player's exact parameter values, before scrolling up and off the screen. The latter feature can be disabled in the settings. Furthermore, both Speed and Power can be manually lowered in the settings menu. This changes the respective parameter by the set percentage; it does not mimic any previous Level's statistics.
After reaching a high enough level, the player can choose to "Rebirth", which removes their speed and levels, but grants them a large amount of Rings, an increase in maximum level before the next rebirth, and an XP multiplier to help level up faster. Levels also serve as prerequisites for unlocking new worlds. Rings can also be found throughout the worlds or obtained through other means, and are used at vending machines to purchase random cosmetic items like trails or pets that provide upgradable benefits to the player, such as increased Rings rewarded per Ring pickup and increased XP per Chaos Orb pickup.
Falling into the aforementioned pets category are Chao. The player can both buy Chao from vending machines or earn them during certain events after meeting specific conditions. There are several types of Chao in the game, each with different attributes. These include the classification of their rarity when obtained from vending machines, which range between "Common", "Uncommon", "Rare", "Epic", "Legendary", "Chaos" and "Exotic", as well as the benefits they grant when equipped, which involving boosting the amount of XPs and Rings earned when the corresponding item is collected. The player can equip the playable character with three of any Chao. Also, while equipped to the playable character, the Chao will gain XPs, which will increase their respective levels and improve the benefits they grant. The player can carry up to forty Chao by default (a trait shared with trails), although that limit can be expanded through in-game purchases. In addition, the player can evolve a Chao if they collect five of the same type. Evolved Chao gives greater bonuses; five times that of an unevolved Chao of the same type. The player can as well grant their Chao one of seven different buffs to their stats at Enchantment Shrines for a sum of one million Rings; strength boosts for boosting the player's power stat; speed boosts for boosting the player's speed stat; Ring pickup boost for increasing Rings gained; XP boosts for increasing Experience Points gained; magnet boosts for increasing item attraction; luck boosts for increasing chances of purchasing rare items from vending machines; and event boosts for increasing event items gained. These buffs also come in five different tiers; the higher the tier, the better the buff. However, Chao can only have one buff at a time. However, the player can re-enchant a Chao any number of times to give it different buffs.
Additionally, Races and other events periodically take place in the game. These allow the player to compete with other players in the game, and grant them varying rewards depending on which place they finish in.
There is also an in-game Shop where the player can buy extras using Robux, the virtual currency of Roblox. The purchases that can be made in this shop are divided into passes that grant permanent benefits to a player, such as more room inventory space, level/rebirth multipliers and negation of the level cap; Boosts that grant effects that last for thirty minutes, such as Ring and XP multipliers and Magnets; and bundles of varying amounts of Rings. In addition, the player can purchase Sonic-themed accessories and clothing (UGC) for their Roblox avatar in another shop. The UGC shop is available near the starting point in Green Hill, at the wooden stage between the totems.
In return for playing the game for certain periods of time, the player can also obtain free rewards from Chests opened in the Redeem section, accessible on the right side of the screen. Contents include Rings and Boosts that are normally only available in the Shop. Players subscribed to Roblox Premium, the paid membership of Roblox, receive double the rewards.
Besides large open Worlds, Sonic Speed Simulator features obstacle courses (referred to as "Obbies"). Completing special Obbies allows the player to obtain additional Rings and unlock new Zones, depending on which Zone that Obby is based on - for example, clearing the "Lost Valley" Obby will grant the player access to the eponymous world.
There are also cyclical events in the game where the player can earn rewards, such as new characters and Chao and trails, by completing certain objectives or buy them with Robux. During the first, "Scavenger Hunt Event" for example, character card fragments would appear in certain worlds every now and then for five minutes. Collecting 100 cards unlocked "Sailor Tails" as a playable character.
The player can play on public servers with other Roblox users or create a private server for themselves and add people to it as their friends. The price of a private server is 99 Robux.

Development
According to producer Brendan O'Brien, the game was developed for three months prior to its release.[4]
On 17 May 2022, it was announced by Gamefam Studios that Nibroc.Rock had been brought onboard for Sonic Speed Simulator in order to further develop 3D models for the game.[5]
Promotional
Sonic Speed Simulator was initially released as a paid beta, which was accessible through a payment of fifty Robux. Players who participated received a free Knuckles Chao pet.
Some updates are promoted with ads displayed on the Roblox website.

- There is a reference to a shot of Green Hill Zone from the 2020 Sonic the Hedgehog film in a background view on one side of the Green Hill world map.
- The pose Sonic makes on an alternate icon for the Master Chao update is very similar to a piece of artwork from Sonic X.
- Sonic and Tails' rarity was originally legendary.
- The "Chef Amy" skin is based on an outfit Amy wore in a piece of artwork from Sonic Channel.
- The "Summer Sonic" skin is wearing the bracelet Amy gave Sonic in the episode "The Last Resort" from the Sonic X anime series. Also, the shirt he is wearing is the same one he is shown wearing in an old Joypolis plush, the glasses he wears are the same one Sonic wears on the ending screen of his story in Sonic Adventure and the shoes he wears are the Light Speed Shoes from the same game.
- During the Summer Event, on the tables under the tent, there are cans of Chaos Cola and Chaos Soda on every table. Also, the tables on the outside of the tent are the same ones from the ending screen of Sonic Adventure.

- The icon for the Metal Madness Event is a reference to cover A of Sonic the Hedgehog #12 from the Sonic the Hedgehog comic book series published by IDW Publishing.

This is a reference to a popular joke among fans that the Classic Sonic from Sonic Generations and Sonic Forces is not the same character as the Classic Sonic in the Sega Mega Drive games, and is instead a character named "Santiago". Under this there is a picture of glasses that look very similar to glasses that the character Kamina wears from the anime Tengen Toppa Gurren Lagann. This was later removed.
- On the side of the Chemical Plant portal in Green Hill, there is a piece of artwork of Dr. Eggman from Sonic Colors'. This image could also be seen on the wall above and to the back of it, by the Lost Valley portal, and on the side of a rock by the waterfall. These were later removed.

The text in Hill Top during the Birthday event.
- During the Birthday event, there was text in Hill Top that reads, "Sega does what Nintendon't." on the back of a rock, this is a reference to a slogan Sega used to promote the Sega Mega Drive. This was later removed.
