Red Star Rings (レッドスターリング,Reddo Sutā Ringu?), more commonly referred to as Red Rings and originally Special Rings, are unique Rings found in several games in the Sonic the Hedgehog series. Red Star Rings are often used to unlock special bonuses.
The Red Star Rings first appeared in both versions of Sonic Colors where they are named Special Rings. Five Special Rings are found in each level in both versions (except Terminal Velocity). Some of these Special Rings are located in easily accessible places, while some require the usage of a Color Power, and others are in hard-to-reach locations. Special Rings will also give a Special Bonus of 30,000 points. In the DS version, if all are collected in an Area, pictures in the gallery are unlocked. When all of the Red Star Rings are collected in the DS version, Sonic unlocks the Infinite Boost along with Sonic Channel-esque artwork of Sonic and Yacker. Collecting the Red Star Rings in the Wii version progressively unlocks the stages in Eggman's Sonic Simulator. Completing a set of stages will reward the player a Chaos Emerald, and when all of the Sonic Simulator stages are completed, Super Sonic mode will be unlocked.
In the console/PC version of Sonic Generations, these rings are referred to as Red Star Rings. In this game, there are five Red Star Rings in each Act. Collecting one unlocks music or concept art. If all the Red Star Rings are collected in an Act, one giant Red Star Ring will hover over the stage and a new Skill will be unlocked.
If the player talks to one of Sonic's rescued friends in the White Space when they have the icon of the Red Star Ring above them, they will give them a hint as to where their respective Act's Red Star Rings are.
Sonic the Hedgehog 4: Episode II
In Sonic the Hedgehog 4: Episode II, one Red Star Ring appears per Act. In this game, the only purpose they serve is for 100% completion as well as an achievement/trophy.
Sonic Jump (2012)
In the 2012 remake of Sonic Jump, there are three Red Rings to collect in each act.
In Sonic Dash, Red Star Rings appear early along the first run of each day, but they can also still be obtained by completing certain objectives, or with real money and serve as a premium currency that can be used to unlock new characters or to buy re-tries for whenever the player fails.
Sonic Lost World
In Sonic Lost World, Red Star Rings are used to unlock extra content. Each Zone has five Red Star Rings to collect. Some Red Star Rings can be obtained only when Sonic uses the Parkour system or Color Powers and some of them come out of bound bells Sonic chases within a Zone. Collecting all the Red Star Rings in the Wii U version of the game unlocks the World's Chaos Emerald. In the Nintendo 3DS version of the game, collecting all the Red Rings in a World will unlock a Bonus Zone where the player can collect additional Red Star Rings. After collecting every Red Star Ring from each Bonus Zone, a more difficult version of the game's final boss fight will be unlocked.
On the Wii U version of the game, the player can earn a Red Star Ring radar by completing any of Omochao's missions, which makes it easier to locate Red Star Rings.
Sonic Jump Fever
In Sonic Jump Fever, the Red Star Rings return as a premium currency. They can be found placed in the Zones, although a limited number of these do so per day. They can also be obtained occasionally from Daily Rewards or from the Daily Spin. However, if the player equips him/herself with the Hero Rare Chao or Hero S-Rare Chao, it can reveal hidden Red Star Rings in the Zone. They are mainly used as the in-game currency to purchase Gold Rings or use the Spin (when the free Daily Spin or video to obtain a free spin are both unavailable). Red Star Rings can also be purchased by the player using real money.
In Sonic Runners, Red Star Rings served as the game's premium currency. They can be earned in very small batches during runs or boss fights, but will mostly be received through daily bonuses and completing episodes. The player can spend Red Star Rings on playing the Premium Roulette to earn Chao and RC vehicles-based Buddies, or exchange them for Rings. During a stage, the player can continue a run through after losing once by paying five Red Star Rings.
Occasionally, the game had campaigns, sometimes in acknowledgement of certain events, that offered the player additional Red Star Rings if they logged in on Sonic Runners within a certain time period or completed certain tasks.
Sonic Forces: Speed Battle
In Sonic Forces: Speed Battle, Red Star Rings can be obtained from Free Chests which contain three Red Star Rings or can be purchased with real money. Red Star Rings can be used to purchase Gold Rings, Loot Chests or immediately unlock any acquired Victory Chests, bypassing the waiting time of unlocking the Chests. The Red Star Rings cost of unlocking the Victory Chests depends on which type of chest is being unlocked:
Required no. of Red Star Rings
As of version 0.0.4, if there is a Victory Chest currently being unlocked, the cost of Red Star Rings required to immediately unlock it will decrease over time.
In Sonic Forces, Red Star Rings appear once again as collectibles that can be found in stages. In this game, collecting them serve as some of the Challenge Missions' objectives; completing such missions will unlock more Costumes and Wispons. Collecting Red Star Rings will also unlock extra stages. When all five Red Star Rings have been collected in a stage, the player can replay the stage to collect Number Rings and Silver Moon Rings.
In the console/PC version of Sonic Generations, when spoken to Rouge after receiving a few Red Star Rings, she will say that she is looking for "Teal Star Rings," suggesting that the Star Rings may come in multiple colors.
