Sonic Chaos, known as Sonic & Tails (ソニック＆テイルス) in Japan, is a 2D Sonic the Hedgehog platform game released for the Sega Game Gear and Sega Master System in 1993, and developed by Aspect Co. Ltd, the same developer who worked on the 8-bit versions of Sonic the Hedgehog 2.
This Sonic game is notable as being the first 8-bit title to feature Tails as a playable character. Not only is it the first game on any system to allow the player to control Tails' flight, it is also the first 8-bit title to introduce the Spin Dash and the Super Peel Out (referred to as the Strike Dash). Also of note is that the game shares the same title music and death jingle as the 8-bit versions of Sonic 2, but in a higher key.

In another bid to conquer the world, Dr. Eggman has taken the red Chaos Emerald, and he's hunting for more. Upon getting his hands on the red Emerald, the remaining five ended up losing their balance and scattered elsewhere, and without the power of the Chaos Emeralds to sustain it, South Island began to sink into the sea. Sonic and Tails are entrusted with saving South Island before it is too late.
The gameplay of Sonic Chaos builds upon the gameplay of the previous 8-bit title, however following the previous game's high difficulty level the difficulty has been decreased significantly for Chaos, as levels are shorter in length and are designed for getting to the end as quickly as possible. In addition, the player can now use the Spin Dash as a move, which is performed by holding and repeatedly tapping the or buttons as either character. The player's character curls into a ball and takes off at great speed, and due to being in ball form is protected from enemy collisions. These additions and changes make the game feel closer to the 16-bit version of Sonic the Hedgehog 2.
The Zone structure remains the same as the previous 8-bit titles in that each Zone spans three Acts, with the first two Acts being standard levels, while the third Act is merely a short run up to the boss. Starting from this game, Rings are now provided in the third Act, making bosses significantly easier. Rings are still handled in the same way that collecting 100 Rings will reset the Ring counter to 00.
The player has a choice between Sonic and Tails. Sonic comes equipped with two moves: in addition to the Spin Dash, he also has the Strike Dash, performed by holding and tapping or once. This move is slightly faster, but since he is standing up he is vulnerable to enemy collisions. However, Sonic will quickly stop unless the D-Pad is held the opposite way he was going. Another disadvantage of this move is that Sonic is heavier while using this move so he slows down quicker. Rolling uphill is less difficult than running uphill. This means that the faster way to go downhill is the Strike Dash, but the faster way to go uphill is the Spin Dash.
Sonic also must collect five of the six Chaos Emeralds. Unlike the two previous 8-bit Sonic games, the Chaos Emeralds are located in Special Stages. To enter these Special Stages, 100 Rings must be collected in one Act. Eggman himself has the sixth Chaos Emerald; the player will get it back if he is defeated and the other five have been found.
Playing as Tails is slightly different but generally easier. Tails runs slower, but he starts the game with 5 lives and 3 Continues (Sonic starts with 3 lives and no Continues). He is also not required to collect the Chaos Emeralds, thus he cannot enter the Special Stage. He has the Spin Dash attack like Sonic, and the ability to fly by pressing and either or . Flying is handled differently than other games as it must be performed from a standing position and he hovers in position if the D-Pad is let go. He stops flying after a short amount of time or if he bumps into a ceiling.
Sonic Chaos features two new items: The Pogo Spring item and the Rocket Shoes item monitor. The Rocket Shoes gave Sonic the ability of even more incredible speed and limited flight. Often, this was enough to blaze through the entire stage. When playing as Tails, the Rocket Shoes monitors are replaced by 10-Ring monitors. The Pogo Spring item also made a limited appearance here, which were basically springs strapped on to Sonic's (or Tails') shoes, and also lasted a limited time. It gave them an unprecedented jump that let them pass otherwise impossible obstacles. The other items are standard Sonic fare (excluding Shield Monitors).
At the end of Acts 1 and 2 of each Zone, a Bonus Panel is spun, with a reward given based on what it lands on:
|No prize is awarded.|
|10 Rings are added to the player's final Ring tally.|
|Sonic gets a 1-Up, Tails gets a Continue.|
|Tails gets a 1-Up, Sonic gets a Continue.|
|Back of Panel|
|The panel must be spun again.|
The prizes the player will get depends on the number of Rings collected at the end of an Act within a certain Zone (Zone 1, 3 & 5/or Zone 2, 4 & 6). The "extra life" bonus can be alternatively won by doing specific times. The player's speed will also be calculated and displayed above the Bonus Panel as a measurement of how quickly they got through the Act. If the calculated speed is exactly 777km/h, the player will receive an extra life.
Enemies: 100 points each.
End Level Ring Bonus: 100 points for each Ring held at the end of an Act. Because the Ring counter resets past 99, the maximum possible bonus is 9,900.
End Level Speed Bonus: Points awarded based on the player's speed calculated after passing the Bonus Panel multiplied by 10. The maximum possible bonus is 9,990.
Zone Clear Bonus: Awarded after defeating the boss of each Zone, before Ring and Speed bonuses are calculated:
- Turquoise Hill Zone: 5,000 points
- Gigalopolis Zone: 10,000 points
- Sleeping Egg Zone: 15,000 points
- Mecha Green Hill Zone: 20,000 points
- Aqua Planet Zone: 25,000 points
- Ring Bonus: 100 points for each Ring held at the end of an Act. Because the Ring counter resets past 99, the maximum possible bonus is 9,900.
- Time Bonus: 100 points for each second remaining.

Much like the previous title, Sonic Chaos had both its Master System and Game Gear versions developed simultaneously, with the Game Gear version having many noticeable differences from the Master System version, mainly presentation differences such as different fonts and designs for the title screen, menus and title cards to take advantage of one system's advantages over the other, and updated music. The core gameplay remains the same, though the third Acts of each Zone were given changes.
The Japanese Game Gear version, Sonic & Tails, received further differences albeit minor, such as using a combination of Master System and English Game Gear versions' Act 3 layouts. It uses the Master System's layouts for Turquoise Hill Zone and Gigalopolis Zone, an altered version of Master System's layout for Sleeping Egg Zone, altered versions of English Game Gear's layouts for Mecha Green Hill Zone and Aqua Planet Zone, and the English Game Gear's layout for Electric Egg Zone. It also includes an exclusive feature intended for a contest that was held in Japan.
